Reasons Your Air Filter Isn’t Cleaning Your Indoor Air

Indoor Air QualityResearch has proven that the small, microscopic, nearly invisible particulates that float around in our indoor air are not good for our health. The American Lung Association reports that airborne particles 2.5 microns or less (called fine particles) are an inhalation hazard as they are “easily inhaled deeply into the lungs where they can be absorbed into the bloodstream or remain embedded for long periods of time.” A recent study also showed that the mortality risk showed 17% increase in areas with high concentrations of fine particles. These small particles also greatly affect anyone that has asthma problems. They can trigger asthma attacks, respiratory irritation, coughing and wheezing.

What is the best way to make sure your indoor air is as clean as possible? The first thing to do is filter the particulates out of the indoor air. This is primarily done when the air is pushed through filter in a forced air HVAC system. However, even if an air filter is changed regularly, it may not be helping your home’s indoor air quality (IAQ).

Air Filter Issues That Reduce Indoor Air Quality

No Air Filter Present

You may thing this never happens, but it does. If you don’t have an air filter in place, it definitely isn’t going to filter any of the air that circulates in your home. This usually happens if the filter is removed because it’s hard to reach – like in a crawl space. Other times it may be taken out and then forgot to be put back in. Many things can happen if an air filter isn’t in place: reduced indoor air quality and potential damage to the HVAC equipment as it builds up with dirt, dust, and debris.

Filter Bypass

Bypass happens when a filter is installed incorrectly allowing air to pass right by the filter instead of through the filter. When this happens, air is not cleaned as nearly well as it should be. The type of filter doesn’t matter – bypass can happen any time a filter is improperly installed.

HVAC Runtime

Filters only clean indoor air when the system is running, pushing air through them. No filtering happens when an HVAC system is off. The mathematical equation for this is Filtration volume = Air flow x Runtime. Many times, homeowners may switch the fan to “on” instead of “auto” and this may work sometimes in certain areas, but higher energy bills are a result. Having the fan run constantly may also worsen indoor air quality by raising the humidity levels, especially in humid climates during the cooling season. Those in a dry climate, keeping the fan set to “on” can help.

Your best bet is to make sure you have the right sized HVAC system for your home to get as much filtering as possible. Also, minimize indoor air pollutants that need to be filtered out with source control, ventilation, and air sealing.

Inadequate Indoor Air Flow

As stated above, air flow and runtime go together. If returned ducts and filters are too small, the pressure in the system increases therefore reducing air flow. This can also happen if an air filter is dirty and not changed regularly resulting in high pressure and low air flow.

MERV Rating

Ranging from 1-16, MERV ratings score the performance level of a filter related to the removal of airborne particles from 0.3-10 microns in size. Microns are used as the measurement for airborne particles and a micron is 1/1000th mm…equal to 1/25,000ths of an inch. Logic would make it seem that you would want to buy a filter with the highest MERV rating possible, right? Oddly, that is not necessarily the case.

Air filters with high MERV ratings mean the filter is highly effective in preventing harmful airborne particles from circulating throughout your home. However, a high MERV rating filter could also be overly effective which, in turn, can prevent the air itself from being to circulate. This is a bad thing and the result may be poorer air quality in your home. Also, if the air is unable to circulate due to more resistance, your HVAC is doing more work than it should be. The result is an inefficient HVAC system, high energy bills, and it can even lead to costly repairs in the long run. Too low of a MERV rating doesn’t filter out enough particulates to keep your indoor air clean.

20x25x1 Home Air Filters

The 20x25x1 air filter is one of the most common sized air filters and can be found at most retail locations. A home’s air filter is quite often overlooked but maintaining it is, in fact, one of the most important steps you can take to keep your HVAC system efficient. Changing your 20x25x1 air filter has the following benefits:

  • Increased overall comfort
  • Improved indoor air quality (IAQ)
  • Increased lifespan of HVAC equipment
  • Decreased energy bills
  • Increased efficiency of cooling and heating

How does your 20x25x1 filter work?

20x25x1 Air Filters Clean Your Home’s Indoor Air

20x25x1 air filters

The EPA has done studies that show indoor air pollution as being one of the top 5 environmental health risks. Multiple sources decrease indoor air quality such as airborne particulates and matter getting indoors,  poor ventilation, increases in temperature and unbalanced levels of humidity. Other sources within your home also increase indoor air pollution. Fumes and smoke from cooking, the use of scented candles and air fresheners, cigarette/cigar smoke, carpet, drapes, furniture and even printers in the home contribute to indoor air pollution.

Improving Your Home’s IAQ

HVAC systems allow air to circulate through a home – air that is brought indoors from outside. During this circulation process, air is forced to pass through the air filter. The 20x25x1 filter traps the particles, dust and debris in the air, therefore pushing clean air back into your home. These particulates include:

  • VOCs (volatile organic compounds)
  • Hair
  • Pet dander
  • Dust
  • Dust mites
  • Vapors, odors, gasses
  • Organic waste
  • Carpet and fabric fibers
  • Smoke and emissions
  • Microbiological growth

Protecting your homes IAQ is possible by reducing the sources that are causing an increase in indoor air pollution. Reducing these sources results in the 20x25x1 air filter effectively capturing these pollutants and returning clean air back into the home. Air filters must be changed on a regular basis to ensure the cleanest indoor air possible.

Air Filters Protect HVAC Systems from Damage

Air filters not only protect indoor air quality, but they also protect your HVAC equipment from damage. Routine HVAC maintenance includes changing the air filters on a regular basis. Damage can happen to your AC system if dust and debris are allowed to build up on the motor and wires. If water collects around the evaporator coils/condensate lines mold can begin to flourish. Any holes and/or leaks within the equipment will allow debris to enter the system. Any of these can lead to very expensive repair costs or even permanent damage to the entire system. A clean 20x25x1 air filter saves you from damage to the following pricey components:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

20x25x1 Air Filters Improve Energy Efficiency

According to the Department of Energy, replacing dirty filters can reduce energy consumption up to 15%. Heating and cooling systems are responsible for nearly 1/2 your energy usage which means that there is a potential savings of 7.5% each month!

For example, in a home that has an energy bill of $100 per month and regularly replaces the air filters, there could be an energy savings of ~$7.50 monthly. Energy bills in the $200+ range will see even more energy savings – up to $30/month.

Other ways to improve indoor air quality:

  1. Housekeeping: Sweep, dust and vacuum floors and carpets, as well as blinds and vents regularly.
  2. Indoor air pollutant sources: Air quality is better in homes with hardwood floors and open windows than in homes with drapes and carpets. Any leaks and holes due to improper insulation will let unwanted pollution in if the home. Limit the sources of indoor air pollutants as much as possible so there is less stress on your 20x25x1 air filter and improve indoor air quality.
  3. Pets: Dander is the dead skin cells from an animal, much like human dandruff. Pets also track in all kinds of dirt, debris, pollen and dander from outside. If possible, keep animals out of bedrooms and off furniture. Wash blankets and floors on a regular basis to help keep the dander at minimum.
  4. Allergies: Seasonal allergies and/or asthma sufferers need indoor air clean to remain healthy and comfortable. Dust and other pollutants in the air irritates respiratory sensitivities.

Analyzing the Air We Breathe

analyzing the air we breatheRecently, many people began thinking about the air we breathe, especially indoors, and the quality of that air. On top of that, it’s also important to understand the process of breathing and what the air we breathe is made up of. This seemingly insignificant subject actually has a great deal of interesting data, including the important role that air filters play in the air quality of our indoor spaces. Spending a lot of time in the unhealthy indoor environment can result in symptoms like a tight chest, wheezing, sore throat, eye, and nose irritation and in some sever cases, dizziness, and nausea. Pleated air filters used in HVAC systems is a highly beneficial way to scrub the pollutants and allergens that cause those symptoms from indoor air. Here’s what you need to know about how we breathe, the makeup of that air and the benefits of air filters.

Did You Know?

  • An average adult inhales and exhales approximately 400 cubic feet of air everyday
  • We average 17,000 – 23,000 breaths per day
  • Oxygen makes up about 20% of our air and our body only requires 5% of that
  • If Earth were compared to an apple, the layer of atmosphere containing the air we breathe would be the skin of the apple

The Anatomy of the Air We Breathe

Air is a combination of multiple gases: 78% nitrogen, 21% oxygen, and 1% argon, carbon dioxide, and trace amount of other gases. There are particles and gases within the air that come from many sources, both nature and man-made. Much of what we breathe is filtered and exhaled, however, there is a host of contaminants that can directly impact our health and our surroundings. Whether the source is indoor or outdoor, naturally occurring or result from a man-made process, all particles are fall into two categories: aerosol or gas. Many types of particles can be captured with the air filters used in HVAC systems.

Aerosols – a suspension of a solid or liquid particle in the air which can be a solid, liquid, or compound:

  • Dust – a solid aerosol resulting from the reduction of a larger material or solid particle. Dust can be created by drilling into a surface (e.g. wood or concrete) or from natural occurrences (e.g. a volcano or sandstorm)
  • Mold – a bioaerosol derived from indoor and outdoor sources such as soil, plants, and moist surfaces such as walls, insulation, clothing, or carpet.
  • Bacteria and viruses- also bioaerosols with millions of varieties that are transported by air currents 
  • Fumes – created from vapor condensation from processes like combustion or welding
  • Fog – a liquid created during water vapor condensation
  • Mist – a suspension of liquid droplets that can include oils, paint, acids, and chemicals
  • Smoke – created from the burning or combustion of organic matter such as wood, coal, or tobacco
  • Smog – air pollution caused by industrial or chemical processes

Gases – a material that can expand indefinitely and fully occupy the space it is in. Gases exist in the form of molecules and include vapors and the gases that make up the composition of air. Gases can be odorous, toxic, and corrosive in nature. The presence of most gases will be recognized, but some (like carbon monoxide) are not detectable by the sense of smell. Gases may originate from chemical, manufacturing, and biological processes.

The Micron

Particles are measured in micrometers (also referred to as a micron), and have the abbreviation “μm”.  A micron is a unit of measurement that is the millionth part of a meter. One inch is equal to 25,400 microns. To put that into perspective, the average human hair is approximately 50 microns and the human eye is only able to see particles that are at least 5 microns in size. Particles measuring less than 1μm make up over 98% of the particles found in the outdoor atmosphere while only 0.005% consist of those measuring 20 μm.

The Role of Air Filters

Air filtration provides a way to attain a higher level of indoor air quality. Originally air filters were intended to simply shield the components HVAC systems and protect them from harmful dust build-up and extending its life. The manufacturing process of air filters has evolved over the decades and filtration media has become more refined and specialized. This allowed us to go beyond system protection into cleaning contaminants, allergens, and other bothersome particles from the air with the use of high-efficiency pleated air filters. The result was a significant improvement in indoor comfort and cleaner air in our homes and businesses.

For the best indoor air quality select the level of filtration based on the types of particles that you aim to capture with your air conditioning  and furnace filters. Choose a MERV rating that targets specific types of particles like pollen, mold spores and pet dander. The higher the MERV rating, the smaller the particle that can be captured. A general guideline for MERV ratings is:

  • MERV 8 – for mild allergies and average dust particles
  • MERV 11 – for moderate allergies and smaller dust particles
  • MERV 13 – for severe allergies and the finest dust particles

The 20x20x1 air filter is one of the more popular air filter sizes and is available at most retail stores. Taking care of your home’s air filter is quite often overlooked but is one of the most important things you can do to keep your HVAC system working at max efficiency. Changing your 20x20x1 air filter:

  • Increases overall comfort
  • Improves indoor air quality (IAQ)
  • Increases your HVAC equipment’s lifespan
  • Decreases energy bills
  • Increases efficiency of heating and cooling

How does your 20x20x1 filter work?

20x20x1 Air Filters Clean Indoor Air

20x20x1 air filters

The EPA reports that indoor air pollution is one of the top five environmental health risks. There are multiple sources that reduce indoor air quality such as allowing airborne particulates and matter to get indoors, poor ventilation, temperatures increases and unbalanced humidity levels. Sources throughout your home also increase indoor air pollution. Smoke and fumes from cooking, scented air fresheners and candles, cigar/cigarette smoke, carpet, furniture and even printers contribute to indoor air pollution.

Improving Your Home’s Indoor Air Quality

HVAC systems allow air that comes indoors to circulate through a home. During this circulation, forced air is passed through the air filter. The 20x20x1 filter traps particles and particulates in the air pushing clean air back into the home. These particulates include:

  • VOCs (volatile organic compounds)
  • Hair
  • Pet dander
  • Dust
  • Dust mites
  • Vapors, odors, gasses
  • Organic waste
  • Carpet and fabric fibers
  • Smoke and emissions
  • Microbiological growth

To protect your homes IAQ you need to reduce the sources that are increasing indoor air pollution. When these sources are reduced, the 20x20x1 air filter effectively captures the pollutants and returns clean air back into the home. Air filters need to be changed regularly to ensure the cleanest indoor air possible.

Air Filters Protect HVAC Systems from Damage

Air filters protect indoor air quality AND protect HVAC equipment from damage. HVAC maintenance includes replacing dirty air filters with clean ones. Particles that cause indoor air pollution can also cause damage to your AC system if dust and debris are allowed to build up on the motor and wires. Water that collects around the evaporator coils/condensate lines leads to mold growth. If there are holes and/or leaks within the equipment they allow debris to enter the system. Any of these scenarios can lead to expensive repair costs or even permanent damage to the whole HVAC system. Using a clean 20x20x1 air filter saves you from damage to these expensive components:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

20x20x1 Air Filters Improve Energy Efficiency

The Department of Energy reports that replacing dirty filters with clean air filters reduces energy consumption up to 15%. With heating and cooling systems being responsible for nearly half your energy usage, that is a potential savings of 7.5% every month!

To break that down, if you regularly replace your air filters and your energy bill is $100/month, there could be an energy savings of ~$7.50 monthly. Energy bills in the $200+ range will see even more savings – up to $30/month.

Other ways to improve indoor air quality:

  1. Housekeeping: Sweep, dust and vacuum floors and carpets, as well as blinds and vents regularly. IAQ decreases when the circulating air from the AC blows particles around the house.
  2. Indoor air pollutant sources: Air quality is better in homes with hardwood floors and open windows than in homes with drapes and carpets. Any leaks and holes due to improper insulation will let unwanted pollution in if the home. Limit the sources of indoor air pollutants as much as possible so there is less stress on your 20x20x1 air filter and improve indoor air quality.

What is the Best Air Filter for My Home?

Which Air Filter is the Best for Your Home?Typically, if you need of a new air filter you go to the nearest hardware store, grocery store or wholesale warehouse and pick a filter that fits into your HVAC system. Picking out a random air filter, however, may not save you money nor improve your home’s indoor air quality. Just like other purchases you make, there are many factors that go into selecting the right air filter for your home. The filter should perform efficiently and cost effectively.

Before making your selection, the first thing to understand are MERV ratings. MERV stands for Minimum Efficiently Reporting Value. It is a numerical value that rates the effectiveness of an air filter. MERV ratings are calculated by measuring the number of particles trapped in a filter compared to the total number the particles in the air trying to go through the filter. This means that if there are two filters in the same room, the filter that traps fewer particles will have a lower MERV rating.

MERV ratings aren’t the only factor involved in choosing the right filter for your AC unit. Selecting the filter with the highest MERV rating may lead to purchasing an air filter that potentially makes your HVAC system less efficient as it will block too much air flow. If this happens, the system is unable to heat or cool enough air to correctly maintain the temperature in your house. This means higher energy bills and the entire system could overheat.

The answer is BALANCE. The best choice is a filter that removes the most pollutants (MERV rating) and allows your HVAC system to perform efficiently. The following are the four different types of filters, their material makeup, their MERV rating and additional information that will help you make a decision.

Fiberglass Filters

Made from spun fiberglass and typically blue in color, these filters are one of the most popular types. They’re MERV rating is between 1 and 4 (low) and they trap 80% of particles 50 microns and larger/25% of particles between 3 and 10 microns. They do a great job of protecting your HVAC unit from large dust particles; however, they do not trap mold, pollen or other small particulates and are not recommended for people with allergies.

Pleated Air Filters

Comprised of folded sheets of cotton or a polyester-blend fabric, pleated filters are folded accordion style that allows for a larger fabric surface in a smaller area. The pleats make it easier for the air to pass through the filter making them more efficient. These air filters have a MERV rating between 5 and 8, trapping 80-95% of particles 5 microns and larger. If you find a cotton/polyester filter with lots of pleats and a MERV value of 6 or greater, this could be an ideal air filter solution. With these ratings, the filter removes a large number of pollutants AND keeps your HVAC system working at max efficiency.

Pleated air filters are also found with high MERV ratings from 11 to 13, trapping particles as small as 0.3 microns. At this efficiency level, they are approximately 2″-5″ thick and fit into box-like housings mounted onto the air handler.

Disposable Electrostatic Filters

Boasting a MERV rating of 10+, these filters are very effective at decontaminating indoor air. Electrostatic filters are composed of multiple layers of self-charging, polyester-blend fibers that create a static charge which attract particulates out of the air. They are framed by a polyester mesh that is positively charged. As air passes through the outer material, particulate matter becomes positively charged which is attracted to the negatively-charged inner material. Electrostatic filters are usually more expensive than fiberglass or pleated air filters.

Washable Electrostatic Filters

These filters are made of washable material, cased in aluminum mesh and framed in aluminum and MERV ratings of up to 10 or higher. For max efficiency, they need to be washed about every 3 months and their quality varies with cost. Higher quality washable electrostatic filters can last up to 8 years! There are some, however, that aren’t high efficiency and its difficult to determine the difference. After the filters are washed, they must be dried completely. Even the littlest bit of moisture left on a filter that is placed back in the air exchange can grow mold and bacteria that is recirculated back through your home.

Can HVACs Spread COVID-19?

COVID-19 and HVAC SystemsWe are in the dead of summer across the country, which means our home’s HVAC systems are in full swing, cooling our indoor air. The United States is also in the middle of the coronavirus pandemic. With more time being spent in our homes, have you ever wondered if our indoor air can circulate and spread the COVID-19 virus? There are a few things to understand first before coming to a conclusion on the topic: how the coronavirus is spread and how HVAC systems work. Here’s what you need to know.

How COVID-19 is Spread:

The spread of the virus is still being heavily researched; however, right now droplet transmission is thought to be the primary method. When an infected person coughs, sneezes or even breathes, particles of breath or spit carrying the virus comes out of the persons mouth or nose. These particle droplets then spread into the air, up to 6 feet (if not more) and can transmit the virus by coming into contact with another person’s mouth, nose, or eyes.

Another possible way the virus is spread is through aerosol transmission. This happens when an infected person sneezes or coughs and the tiny COVID-19 infected particles linger in the air and are carried around in air currents, spreading the virus further. There isn’t concrete evidence on to what extent aerosol transmission spreads the virus, but it is does occur and mainly in closed indoor areas.

This leads into the chance that air conditioning could potentially transmit the virus. Your HVAC system continually circulates the air throughout your home and could, potentially, suck in the virus particles expelled from an infected person and then blow these particles back out into the indoor air, much further than just the room you’re in. Other infectious diseases like smallpox, measles, SARS, chickenpox, tuberculosis and influenza all have been shown to spread through improperly used HVAC systems.

How HVAC Systems Work

HVAC systems don’t bring fresh air in from outside, rather they recirculate air in the home. When working properly, HVAC systems should improve your home’s IAQ (indoor air quality) by removing dust, dander, dirt, and other debris and by controlling the humidity in your home via ventilation. When your home is properly ventilated, contaminated air and excess humidity are vented out of your home year-round.

With forced air systems, air is passed through an air filter that traps volatile organic compounds (VOCs), airborne particulates, mold, dust, and allergens. Improving air filtration is the most beneficial thing that can be done to reduce the effects of poor indoor air quality. Air filtration provides a means to attain the desired level of indoor air quality.

HVAC Systems and COVID-19

Now that you know how the coronavirus is spread and how an HVAC system operates, the conclusion would be that yes, theoretically virus infected particles in the air could, in fact, be sucked into the AC unit and circulated around your home. However, definitive answers about this topic are not readily available as there has only been a little bit of research on the topic.

The main thing is to make sure your HVAC system is working properly and efficiently – especially regarding ventilation. During the summer months when we go indoors to find comfort in the air-conditioned rooms, there is less ventilation and more opportunity for the disease to spread. And it’s not really the air conditioner’s fault. It’s more about when inside a home or building, you are not socially distancing and re-breathing air that others around you just exhaled. Combine that with doors and windows being shut to keep the cool air inside, there is virtually no fresh air flowing and everyone is breathing and re-breathing the same indoor air. The good news is this is mainly more of a concern in public indoor places. When you’re at home, contracting COVID-19 via air conditioning units or through air currents is no more probable than the virus being spread by close contact with contaminated surfaces.

16x25x1 air filters

According to the EPA, one of the top five environmental health risks is indoor air pollution. Factors that cause a decline in indoor air quality include multiple sources that allow airborne particulates and matter to get indoors, poor ventilation, increase in temperatures and off-balance humidity levels. There are sources throughout your home that attribute to indoor air pollution. Smoke from cooking, air fresheners and candles, carpet, furniture, cigarette smoke and even printers contribute to indoor air pollution.

Can You Improve Your Indoor Air Quality?

Yes! HVAC systems allow air that is coming indoors to circulate throughout the home. It is during this circulation that air is forced to pass through the air filter. The 16x25x1 filter traps the particles and particulates in the air therefore passing clean air back into the home. These particles and pathogens include:

  • VOCs (volatile organic compounds)
  • Hair
  • Pet dander
  • Dust
  • Dust mites
  • Vapors, odors, gasses
  • Organic waste
  • Carpet and fabric fibers
  • Smoke and emissions
  • Microbiological growth

The main way to protect your homes IAQ is to reduce the sources that are contributing to indoor air pollution. As a result, the 16x25x1 air filter can effectively capture the pollutants and return clean air back into your home. Most importantly, your homes air filter needs to be changed regularly to ensure the cleanest indoor air possible.

Air Filters Protect Your HVAC System from Damage

Air filters not only protect indoor air quality, but also protect HVAC equipment from damage. Regular maintenance of a HVAC system includes changing dirty air filters with a new, clean one. The particles that cause indoor air pollution can also destroy your AC system. If dust and debris build up on the motor and wires, and water collecting around the evaporator coils/condensate lines lead to mold growth. Holes and/or leaks within the equipment also allow for debris to enter the system. Any of these factors can cause expensive repair costs and even permanent damage to the whole system. Using a clean 16x25x1 air filter saves you from damage to these pricey components:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

16x25x1 Air Filters Help Improve Energy Efficiency

According to the Department of Energy, replacing dirty filters with clean air filters can reduce energy consumption up to 15%. Combine that with the fact that heating and cooling systems are responsible for nearly half your energy usage, there is a potential savings of 7.5% each month.

For example, let’s say your home’s energy bill is $100/month. If you regularly replace your air filters, there could be an energy savings of ~$7.50 monthly! Energy bills in the $200, $300, $400 range are looking at even more savings – up to $30/month. Regularly maintaining your HVAC system with clean air filters is definitely worth it, but there are other ways it saves money as well.

Other factors to take into consideration to improve indoor air quality:

  1. Housekeeping: Regularly sweep, dust and vacuum floors and carpets, as well as blinds and vents. The circulating air from the AC blows particles around the house, worsening IAQ.
  2. Indoor air pollutant sources: Drapes and carpets in the home contribute to decreased air quality more than in homes with hardwood floors and open windows. Leaks and holes let unwanted pollution in if the home is not properly insulated. Limiting the sources of indoor air pollutants as much as possible will put less stress on your 16x25x1 air filter and improve indoor air quality.
  3. Pets: Like human dandruff, dander is an animal’s dead skin cells. Pets can track in all kinds of pollen, debris, and dander from outside as well. If possible, keep pets off furniture and out of bedrooms. Regular washing of blankets and floors will help keep the dander at minimum.
  4. Allergies: Seasonal allergies and/or asthma sufferers need indoor air clean to be comfortable and remain healthy and comfortable. Air filled with dust and other pollutants aggravates respiratory sensitivities.

Moldy vs Musty

musty or moldy?It’s a fact that every home has its own unique odor or smell. A home’s “smell” reflects the nature of the home’s environment and those that live there. There are other factors too that also play a role in the odor in a home and some of them can be cause for concern. Environmental factors such as heavy rain and seasonal changes can bring with them that “musty” smell, but when does that smell mean you should be worried about a bigger problem? The first thing to know is the difference between a “musty” smell and a “moldy” smell.

Musty or Moldy? What’s the Difference?

If you get a whiff of a musty or moldy smell, you know that something isn’t right. These smells are caused by the presence of mold or mildew, both of which are fungi and thrive in moist places but there are differences between the two.

Mold, as a substance, is typically thicker and has the ability to penetrate deep into the material it grows on, therefore can cause more structural damage. It can grow many places, but is primarily found on building materials like flooring, walls, ceilings and home contents like clothing, books, and cardboard. Mildew, on the other hand, is a powdery or downy substance that grows on surface of things, most often plant materials like flowering or decorative plants and fruits and veggies.

The main way to tell the two apart is how strong the odor is that you smell. Musty odors are not as strong as moldy odors. Either way, smelling a musty or moldy order should alert you to the possibility of mold growth. It is important to take the appropriate steps quickly not only to prevent damage to your home, but also prevent a lingering musty odor that you just can’t seem to get rid of.

Musty Smell and Mold Growth Prevention

  1. Investigate Possible Sources of Moisture Buildup: Check for any water leaking from the plumbing, roof, and walls and make sure all air conditioning units and drain lines aren’t clogged/leaking. Also look for condensation around exterior walls and windows and examine your fridge/freezer drip pans and door seals. Wastebaskets and trashcans should also be looked at to make sure there is no liquid waste lingering behind, as well as any materials that may have gotten wet in the past (like carpet, cardboard, magazines, books, newspapers, etc.)
  2. Avoid Moisture: High humidity levels, general dampness, and recurring condensation can all cause a musty smell. Stay on top of higher moisture areas since dampness is a breeding ground for mold growth and it’s most likely beginning to form once you notice the musty smell.
  3. Clean Leaks Right Away: Everything must be thoroughly dry within 48 hours, otherwise mold will begin to grow in the areas that are still damp.

The Consequence of Mold Growth

An even more dangerous consequence of mold growth is the spread of mold throughout your home. From its breeding ground in the drip pan and other areas of your home, millions of airborne mold spores are spread every hour. The microscopic particulates have the perfect opportunity to slip into your AC systems airflow and circulate through the HVAC ducts, contaminating your indoor air. Mold spores can cause health issues, asthma, and allergies, especially affecting those with weakened immune systems. The NIH (National Institutes of Health) also links household mold to the development of childhood asthma.

Benefits of Attic Fans and Ventilation

attic fans and proper attic ventilationHeat rises by nature and the highest hottest spot in your home is the attic.  Even on a relatively warm, 80-degree day, your attic can reach upwards of 100 degrees. These extreme temperatures can be damaging to the major components in your home such as insulation, venting, plumbing and electrical wiring that are often located in the home’s attic space. The good news is, attic fans can make a significant difference in energy costs and in the lifespan of major components mentioned above. Because of this, new homes are being built with whole house fan systems which prevent heat from building up in the dead air spaces of the house.

Benefits of Improved Attic Ventilation

Energy.gov reports that ventilation is the least expensive and most energy-efficient way to cool buildings. Ventilation works best when combined with other methods that avoid heat build up in your home.

Attic fans are now integrated with the roof shingles and use very little energy (less than 300 Watts each). The attic essentially acts as a “buffer zone” between the interior of your home and the outside world, so its important to regulate the temperature in this zone, therefore maintaining a consistent temperature in your living space. Attic fans can:

  • Reduce upper floor room temperatures by an average of 10 degrees
  • Lengthen the life of roofing materials and major home components
  • Save up to 30% on home air-conditioning costs

Another layer of protection from the heat and cold for your home is  attic insulation. Attic insulation works by hindering the upward movement of heat, keeping cooler air in during the summer months and warm air in during the winter months. It also contains built in paper or aluminum foil that is forward facing on the insulation panels. These are air-vapor barriers keep moisture that rises up from inside the home from penetrating the insulation.

Attic and roof ventilation are important components to regulating temperature and moisture levels in the home as the weather conditions and seasons change. When it’s cold outside, air can leak in around attic access panels, ceiling light fixtures, exhaust fans, etc., which brings outside moisture into your home’s attic space. Even just going into the attic to get something from storage can significantly increase the moisture level in your home as warm moist air is allowed in through the open access panel.

Types of Attic Ventilation

  1. Non-Mechanical Attic Ventilation – Also called “gable vents”, this type of ventilation is found in many older homes (pre-1980). They are screened and louvered vents that are located up near the roof peak in the side walls of the attic. They are quite efficient at keeping the highest airspace in the attic cooler; however, in areas where there is no air movement, they can often cause hot spots. If your home is equipped with gable vents, you’ll want to consider installing a fan as well which will eliminate the hot spots and keep things cooler. The other option is to use soffit vents and ridge vents, both of which provide adequate non-mechanical venting. Unfortunately, most roof designs do not allow for adequate non-mechanical ventilation alone for optimal performance.
  2. Solar and Electric Attic Fans – Solar powered attic fan or roof vent does significantly improve air flow in the attic space but is not as powerful as an electric fan. Without an attic fan, temperatures in your attic can reach upwards of 150 degrees during the hottest seasons. The fan creates steady air-flow through the attic space; however, if too much air flow is exchanged between outside and the attic, moisture from rain and snow can permeate. In areas of the county with high humidity/wetness, a humidity control system in your attic is recommended as well to prevent moisture issues. The two most common types of electrical/solar attic fans are roof top and gable end. Electric fans are more powerful and cost efficient while solar powered models are most costly but leverage green electric power. Whichever you choose, the attic fan(s) you install should have a programmable thermostat and a firestat, which shuts the fan off in case of fire. Avoid plastic options and go for all metal as well as models that that have solid screens to keep pests out of your attic.
  3. Whole House Fan Systems – Whole house systems keep dead spaces from heating up and pull cool air throughout the home. For those that live in milder climates where the temperature stays below 82 degrees, they can being used as an alternative to traditional home air conditioning. This is also the case for older homes where its too expensive or difficult to install a central air. One potential downfall for whole house fan systems is noise but the system should run quietly and efficiently if it is engineered correctly. Fans with more blades will be quieter than those with fewer blades and the fan should be mounted with foam or rubber strips to reduce vibration and sound.

Air Filter FAQs

air filter FAQsAll homes that has conditioned air running through the home’s HVAC duct work have air filters that need to be changed on a regular basis. They are not in plain sight, so they are often forgot about. However, they play an important role of cleaning the air before it is circulated through your home. Dust and other airborne particulates are removed from the air as it is forced to/from the cooling or heating mechanism and out through the vents. If the air filter becomes clogged, it can cause costly and irreparable damage to your HVAC system as it must work harder to cool or heat your home. No matter your living situation, a clean air filter is key to keeping your home comfortable and for the longevity of the components of your HVAC system.

Frequently Asked Questions About Air Filters

What Can Happen if I Don’t Change My Air Filter Regularly?

Air filters have a relatively simple function, but they can’t do their job effectively if they are not clean. Many different problems can arise from a dirty air filter, such as:

  • Dust and other airborne particulates build up on the mechanical components (i.e. fan blade and motor).
  • Allergens and dirt accumulate on the duct work walls.
  • Dirt can block or clog the HVAC coils.
  • The same coils can freeze due to lack of air flow.
  • The HVAC system cannot perform efficiently and increase your monthly energy bills.
  • A filter that doesn’t fit right allows dirt to bypass the filter.

How Do Air Filters Affect IAQ (Indoor Air Quality)?

Air filters primary job is to screen out any particles, even microscopic ones, from going through the HVAC system. Home-air pollutants can be particulate matter or even gas. There are many things that affect your home’s IAQ including:

  • Dust
  • Dust Mites
  • Spores
  • Mold
  • Viruses
  • Pollen
  • Pet Dander
  • Hair
  • Bug Parts
  • Lint
  • Ash
  • Pesticides
  • Tobacco, wood, or food smoke
  • Paint or other vapors
  • Cleaning product fumes

Do You Use the Same Filter For Heat and Air Conditioning?

Yes. The term HVAC stands for Heating, Ventilation, and Air Conditioning meaning it serves as a furnace and AC unit. The most common systems have hot and cold air that travels through the same ducts so they use the same filter, even though you may hear them called furnace filters or air conditioning filters. Filters can be found between the duct work and the mechanical components where the air travels in the air handler/exchange system.

How Often Should Air Filters be Changed?

The frequency in which an air filter should be changed depends upon your HVAC system and your preferences. The primary recommendation is to change the filter once a month when the system is being used regularly. It’s a good idea to pick a date each month and set a calendar reminder for yourself to change the filter. You can also check to see if the air filter needs to be changed by holding it up to a light source. If you can’t see through the filter, it’s time for a clean replacement.

Which Filter is Best for My Home and Family?

Selecting the right filter for your home and family takes a little self- assessment. Consider asking yourself the following questions to guide your decision. Any of the answers to them might affect which filter you decide to purchase – as well as how often you will change it.

  • How many people currently reside in the house?
  • Is the house cleaned on a regular basis (especially dusting and vacuuming)?
  • Are you in an area with open fields, roads, or other dusty areas?
  • Are there fur-babies in the house?
  • Does anyone in the house smoke?
  • Are you or other family members allergy sufferers?
  • How do you feel about the air quality in your home in general?

How Do I Change Air Filters?

It is just as important to correctly install your filter as it is to change it. It is easiest to change your filter if your unit isn’t active, if it is, turn it off. After locating the air filter housing, look at how it is sitting in the slot and make note of the direction the arrow is pointing. You may even want to consider marking the arrow direction on the frame of the housing with a permanent marker to make sure you always put it in the correct air-flow direction. Then, pull the old filter out, match up the arrows on the frame and the clean filter and slide the new air filter into the housing. That’s it!

What Size Filter Should I Get?

In addition to the directional arrow on the air filter, you will also see numbers denoting the filters width, length, and thickness. This is the air filter size your HVAC unit takes and should be the size you always order. Using the correct-sized filter is also important so your filter can do its job properly and not allow dirt and debris to bypass the filter. It should fit in the slot snugly, with no major gaps on the size and you should never have to force it into the housing.

Do Air Filters Help Me Save Money?

Yes, they do! The Department of Energy reports that replacing dirty filters with clean air filters can reduce your energy consumption up to 15%. When you combine that with the fact that your HVAC system is responsible for nearly half your energy usage, there is a potential savings of 7.5% each month. So, if your energy bill is $100/month, you could save $7.50 on each monthly bill just by changing your air filter! Is your energy bill in the $200, $300, $400 range? You’re looking at even more savings – upwards of $30 every month.
