Air Quality Issues

Portable Air Cleaners

Portable air cleaners and/or upgrading the air filter in your furnace or HVAC system can help improve indoor air quality. The Guide to Air Cleaners in the Home contains more information on selecting the right air purifier.

Our indoor air quality can be impacted in many ways. Sometimes there are actions we can take to prevent from getting sick, like cleaning our house to remove allergens or checking air advisories to learn when to stay indoors.

Our Breathe Easily fact sheet, P-02166 provides more ideas to protect yourself from common indoor air pollutants.

The special topics page has more information about outdoor air concerns.
