What Causes Poor Indoor Air Quality?

Spring increases allergens that can worsen indoor air quality (IAQ), even inside your home. IAQ affects health and comfort and can be impacted by mold, pet dander, dust, chemicals, and smoke.To improve air quality, regularly change air filters, clean ductwork, control humidity (30–50%), and use an air purifier. These steps help reduce allergens and keep your home’s air cleaner and healthier.
