Easy ways you can improve indoor air quality
Reduce indoor allergens that can trigger respiratory problems and other issues. It may feel cozy being sealed in tight against the cold in your home during the chillier months of the year, but for people who are sensitive to indoor allergens or have respiratory problems, winter can exacerbate problems. Stale indoor air and heating systems can increase the amount of allergy-inducing dust mites, pet dander, and mold spores circulating through your house.
