A healthy home begins with cleaner air. Improve the air quality in your house by reducing the amount of airborne allergens with a Filtrete™ Micro Particle and Airborne Allergen Reduction Hammock Filter. Using electrostatic technology, this high-performance filter attracts and captures large and microscopic airborne allergens such as pet dander, mold and bacteria, smoke and dust. For maximum performance, replace your Filtrete™ Filter seasonally (every 90 days) to ensure you and your household are breathing cleaner air.
