All About Dust & Dust Mites

dust and dust mites

Have you ever gotten done cleaning and turned around only to see dust particles on the surfaces that you had just wiped down clean? Every home has dust and, unfortunately, there isn’t anything you can do to totally prevent or eliminate it entirely; however, there are some ways that you can control it. Dust and dust mites are one of the primary causes of indoor household health issues that include asthma, allergies and respiratory problems. So what can you do to minimize and manage the dust in your house and home?

What is Dust?

There are many factors that contribute to the production of dust, but first it’s important to understand what dust actually is. According to, dust is “airborne particulate matter ranging in diameter from 10 to 50 microns, generated by activities such as cutting, crushing, detonation, grinding, and handling of organic and inorganic matter such as coal, grain, metal, ore, rock, wood.” Within dust, there are also tiny bugs called dust mites that survive on the skin cells shed from humans. They are commonly found in rugs, carpets and upholstered furniture, as well as commonly seen in bedrooms. Dust mites are one of the most common year round triggers of asthma and allergies and in a warm, humid house, dust mites can survive all year long. With excess dust in the home, and humans shedding on average 1.5 grams of skin each day, it’s important to keep that dust under control in order to help reduce and minimize the amount of dust mites living in your house.

How to Control Dust and Dust Mites

There are four main or primary problems that can contribute to dust in your home. Luckily, there are ways to remedy these issues which will in turn help reduce the dust in your house.

1. Air Filters

If you have excessive dust in your home, the most likely culprit or cause is a dirty or cheap HVAC filter that isn’t working efficiently enough to effectively clean the air. A clean, efficient air filter prevents dust and debris from collecting on the mechanical parts of your heating and air conditioning system, as well as minimizes the dust levels in your home’s air. Using a high-efficiency pleated filter provides a large surface area with a considerable amount of dust-holding capacity. Pleated filters trap and hold several grams of dust that would otherwise be blown into your ducts and back into your air,  which then settles on those surfaces you had just dusted.

To control average levels of dust, we recommend a minimum of a MERV 8 rating on your home air filter. For greater protection from smaller dust particles (fine, suspended dust), a higher MERV rating is recommended. As the MERV rating increases, the finer the particles that are captured by the filter, thus removing a higher percentage of dust and microscopic particulate matter.

Battling dust that continues to reappear on bookshelves, tables, window treatments, and decor is a constant point of frustration for many people. It is virtually impossible to totally eliminate the dust because there are so many sources, but your air filter is a great supporter of your fight to reduce dust as much as possible.

2. Leaky Ducts

If you have efficient, clean air filters and are still battling large amounts of dust, leaky ducts may be your actual problem. If there is a leak in your ducts, they could be releasing dusty, unfiltered air back into your home. When you turn on an HVAC system that has ducts with holes or leaks, the ducts suck up the dirt, dust, and other contaminants in and around your crawl space/attic which then gets blown out of the air vents in your home, reducing your indoor air quality and increasing your energy bills. If you notice that your energy bills are higher, have hot and cold spots in your house or see dirty/lint covered vent registers, you may have leaky ducts present.

The best way to resolve this is to call an HVAC technician who can perform a pressure test that will tell them if the ducts need to be resealed. Getting your ducts cleaned and resealed by a professional will save you money in the long run by controlling your indoor temperature, reduce energy costs and most importantly, reducing the amount of dust in your home.

3. Humidity Level

The humidity level both on the outside and inside of your home is another main cause of dust. If you live in a dry climate, or perhaps in a dry season, this can affect the amount of dust in your home. Relative humidity inside and out also contributes to the survival of dust mites, so is related to the amount of dust mites in your home. According to the American Asthma and Allergy Foundation of America (AAFA), dust mites thrive in temperatures of 68 to 77 degrees Fahrenheit (20 to 25 degrees Celsius). They also like humidity levels of 70 to 80 percent. So, to put it simply, there will be a lot of dust in the desert, but relatively no dust in the rain forest.

If your indoor air is too dry, you’re going to see more dust in the air. The solution for this is to invest in a humidifier that will help you find a balance in the humidity level in your home. It’s also important to note that dusty and dry air may be a signal that there is a problem with your HVAC system, so if the dust is excessive, you’ll want to get your system checked out.

4. Flooring

The last primary factor that affects the amount of dust is the type of flooring in your house. If your home is carpeted, research has found that carpet harbors dust and dust mites; however, it also holds in the dust making it easier to vacuum it up. Controversially, hard floors don’t hold onto dust and dust mites, but they do contribute to the stirring up of the dust and getting it back into the air when vacuuming, sweeping or simply walking though the house. Regardless of the type of flooring that you have in your house, you’ll want to have a high quality vacuum cleaner that sucks up the dust and dirt, efficiently trapping it so it isn’t released back into the air that you and your family breathe.

US Home Filter is Here For You

Nobody wants to breathe dirty air. There’s no doubt that reducing the dust in the air in your home is highly beneficial for everyone – family members and visitors. The air that you breathe can have a significant impact on allergy symptoms, asthma triggers, and your overall level of comfort. Your air transports allergens and contaminants, allowing them to be inhaled or to settle on surfaces where they can spread to other areas. Using high-efficiency pleated air filters is a great added level of defense in helping to clean your home’s air from allergens and dust. Using a minimum of a MERV 8 rating will help to collect large amounts of dirt and debris, not only protecting your HVAC system, but going above and beyond by capturing common allergens such as pet dander, dust mite debris, pollen, and mold spores. Upgrading to a higher level such as MERV 11 or MERV 13 is recommended for those who desire a greater percentage of dust collection and trapping the smallest allergens.
