18x20x1 Standard Air Filters

The 18x20x1 air filter is a standard sized filter and available at many retail locations. Air filters are easily forgotten about; however, maintaining them is extremely important and keeps the HVAC system efficient. Changing your 18x20x1 air filter has the following benefits:

  • Increased comfort
  • Indoor air quality (IAQ) improvement
  • HVAC equipment lifespan extension
  • Lowered energy bills
  • Greater cooling and heating efficiency

How does your 18x20x1 filter work?

18x20x1 Air Filters Clean Your Home’s Indoor Air

18x20x1 air filters

A EPA study reported indoor air pollution as one of the top 5 environmental health risks. Airborne particulates and matter getting indoors, high temperatures, unbalanced humidity and poor ventilation all decrease indoor air quality (IAQ). Other sources in the home that increase indoor air pollution are: cooking fumes/smoke, burning scented candles, spraying air fresheners, cigarette/cigar smoke, furniture/carpet/drapes, and even printers.

Improving Your Home’s IAQ

An HVAC systems job is to allow air circulation in a home, bringing outdoor air inside. During this process, the outside air is passed through the air filter. 18x20x1 air filters trap dust, particles, and debris from the air and push clean air back into the  home. These particulates include:

  • Volatile Organic Compounds (VOCs)
  • Human hair
  • Pet dander
  • Dust
  • Dust mites
  • Vapors, odors, gasses
  • Organic waste
  • Carpet/fabric fibers
  • Smoke and emissions
  • Microbiological growth

By reducing the sources that are causing the increase in indoor air pollution, you can protect your homes IAQ . When these sources are reduced, the 18x20x1 air filter can effectively capture these pollutants and return clean air back into the home. Air filters must be changed on a regular basis (every 1-3 months according to manufacturers directions) to ensure the cleanest indoor air possible.

Air Filters Protect HVAC Systems from Damage

Air filters protect indoor air quality AND protect damage to the HVAC equipment. Routine HVAC maintenance involves changing air filters on a regular basis. Damage can occur when dust and debris build up on the motor and wires. Water that collects around the evaporator coils/condensate lines is the perfect breeding ground for mold. Holes and/or leaks in the equipment left unfixed allow debris to enter the system. All of these circumstances can lead to very expensive repair costs or even permanent damage to the entire system. A clean 18x20x1 air filter prevents damage to the following expensive components:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

18x20x1 Air Filters Improve Energy Efficiency

The Department of Energy reports that replacing dirty filters can cause a 15% reduction in energy consumption! Seeing as heating and cooling systems are responsible for ~1/2 your energy usage, there is a potential savings of 7.5% each month!

That means that a home with an energy bill of $100/month (where the air filters are regularly replaced) could see energy savings of ~$7.50 monthly. Energy bills in the $200+ range save even more  – up to $30/month.

Other ways to improve indoor air quality:

  1. Housekeeping: Sweep, dust and vacuum floors, carpets, blinds and vents.
  2. Indoor air pollutant sources: Choose hardwood floors over carpets and open windows over drapes. Seal any leaks and holes. Limit indoor air pollution sources as much as possible. These steps will put less stress on your 18x20x1 air filter and improve indoor air quality.
  3. Pets: Dander is the dead skin cells from an animal. Pets also track in all kinds of dirt, debris, pollen and dander from outside. Try to keep animals out of bedrooms and off furniture. Wash blankets and floors regularly to keep the dander at bay.
  4. Allergies: Seasonal allergies and/or asthma sufferers need clean indoor air to stay comfortable and healthy. Dust and other particulates in the air can irritate respiratory sensitivities.
