A healthy home starts with cleaner air. Improve the air quality in your home by reducing the amount of airborne allergens with the Filtrete™ Allergen Defense Microallergenic Air Purifier Filter. Using electrostatic technology, this high-performance furnace filter turns your central heating and cooling system into an air purifier for the whole home by attracting and capturing microscopic allergens like pet dander, smoke, and dust, while handling larger allergens like mold spores and pollen. For optimal performance, replace your Filtrete™ filter every season (every 90 days) to ensure you and your family breathe cleaner air.
