Did you know, people spend as much as 90% of their time inside their homes, offices, schools and cars? For those with allergies and asthma, air quality is important both indoors and out.

What Impacts Your Indoor Air Quality?

Air quality is a measure of gases and small particles in the air that can be harmful to your lungs. Items in your home release gases and irritants into the air. Allergens (like dust mites and pet dander) also impact your air quality. Outdoor air pollution (traffic exhaust, wildfire smoke, smog, etc.) can make its way inside to worsen your indoor air quality.

Some sources of indoor allergens include:

  • Dust mites
  • Pets
  • Cockroaches and mice
  • Mold and damp areas
  • Wall-to-wall carpet
  • Soft furniture and stuffed toys
  • Mattresses
  • Pillows and bedding

Some sources of indoor air pollution include:

  • Scented household cleaners and air-fresheners
  • Fuel-burning heat sources
  • Smoke from cooking, candles, fireplaces or cigarettes, cigars, pipes and vapes
  • Vehicles or lawnmowers stored inside garages
  • Fumes from new furniture and carpet
  • Building and paint products
  • Pesticides
  • Radon
  • Cosmetics, perfumes and hair sprays

What Can You Do to Improve Indoor Air Quality?

The best way to improve indoor air quality is to get rid of the sources of allergies and irritants. Here are a few tips:

Establish regular cleaning routines.

Remove scented candles and throw pillows.

Use a dehumidifier to reduce growth of dust mites and mold.

Replace carpets with solid surface flooring if possible. Otherwise, vacuum weekly and have professional cleaning done a few times per year.
