Why Indoor Air Quality Matters
Poor indoor air quality can contribute to allergies, asthma symptoms, headaches, fatigue, and lingering odors. Dust, pollen, pet dander, mold spores, and bacteria can circulate through your HVAC system if not properly filtered or ventilated.
Improving indoor air quality can help:
-
Reduce allergens and airborne pollutants
-
Improve respiratory health
-
Eliminate stale or musty odors
-
Balance indoor humidity levels
-
Increase overall comfort year-round
