A healthy home begins with cleaner air. Improve the air quality in your house by reducing the amount of airborne allergens with a Filtrete Healthy Living Elite Allergen Filter. Using electrostatic technology, this high-performance filter proactively captures dust, bacteria, germs, viruses and allergens from the air, and is five times better than non-electrostatic filters at capturing small particles. For maximum performance, replace your Filtrete Filter seasonally (every 90 days) to ensure you and your household are breathing cleaner air.
