Clean Air at Home: Ventilation and Filtration Basics
Practical ventilation and filtration basics for cleaner indoor air — exhaust fans, fresh air, filters and portable air cleaners.
This guide is general information, not medical advice. If you have health concerns, please consult a medical professional.
Ventilation
Bringing in fresh air and exhausting stale, moist air is one of the simplest ways to improve indoor air. Use kitchen range hoods and bathroom fans that vent outdoors.
Filtration
Upgrading HVAC filters (following your system's specifications) and using portable HEPA air cleaners can reduce airborne particles.
Source control
The EPA notes that reducing sources — fixing moisture problems, choosing low-VOC products and storing chemicals properly — is usually the most effective approach. Testing helps you know which sources matter in your home.
