Indoor Asthma Triggers

According to the Environmental Protection Agency (EPA), Americans spend up to 90% of their time indoors. Many indoor allergens and irritants can play a significant role in triggering asthma attacks. Indoor asthma triggers include mold, tobacco smoke, cleaning supplies, pets, pests and pesticides, gas stoves, and other irritants. If your asthma is triggered by allergies, using multiple strategies to remove or minimize indoor allergens (such as dust mites or pet dander) may be helpful.

This 2-page fact sheet offers tips on controlling allergens and irritants in your home. For additional information on indoor asthma triggers, see Asthma Triggers at Home (Spanish).
