  4. 5 of the Most Common Indoor Biological Pollutants and What to Do About Them
  • 5 Surprising Things That are Impacting Your Indoor Air

    Ways to minimize the impact of biological pollutants in your home.

    Pet dander can contribute to the makeup of your indoor air.
    • Biological pollutants may be present in the complex makeup of your indoor air—and they’re often small enough to be inhaled by you and your family. Here, we identify a few of the top biological culprits and offer tips for minimizing their impact.

    • Mold spores

      The Asthma and Allergy Foundation of America describes spores as the “seeds” of mold that travel through the air. Molds live nearly everywhere, and when a mold source is upset, spores can wind up in your air and may be ingested, potentially leading to an allergic reaction or asthma**.

      Tip: Use exhaust fans in bathrooms and in the kitchen.

    • Pet dander

      Although the proteins in pet dander (aka dead skin cells) are harmless, they’re still not doing your indoor air quality any favors if you or a family member has a sensitive immune system***. Dander can’t be eliminated completely, but it can be significantly reduced through regular cleaning, according to the Environmental Protection Agency*.

      Tip: Brush your pet outdoors to help remove dander.

    • Pollen

      If you suffer watery eyes, a runny nose and fits of sneezing when pollen gets into the air, you’re not alone. Millions of people react this way to airborne pollen in the spring, summer and fall****. The Lawrence Berkeley National Laboratory explains that the allergens can find their way indoors through open windows and doors, and can hitch rides on clothing*****.

      Tip: Keep windows closed and opt for air conditioning when pollen counts are high.

    • Dust mites

      According to the EPA, some of the most powerful biological allergens come from household dust mites***. They are too small to see with the naked eye, but look like white bugs with eight legs under a microscope. They thrive in warm, humid weather, so keeping indoor humidity under control is key to managing dust mites in your home******.

      Tip: Wash bedding weekly in 130°F water*.

    • Bacteria

      People, animals and debris from soil and plants carry and transport bacteria, which are frequently associated with standing water, wet surfaces and water-damaged materials.

      Tip: Make an effort to fully clean and dry water-damaged areas within 24 hours. Because it’s tough to completely remove biological contaminants from damaged materials, removing and replacing might be a healthier option*.

    • Air Improvement Strategies

      While each contaminant above requires its own special attention, some home care measures can help stunt the growth of several biological contaminants.

      One such tactic: the EPA recommends keeping the relative humidity in a home between 30 and 60 percent*.
