Filtrete air filters 20 x 25 x 1

Product Overview

A healthy home begins with cleaner air. Improve the air quality in your house by reducing the amount of airborne allergens with a Filtrete™ Allergen Defense Micro Allergen Filter. Using electrostatic technology, this high-performance filter turns your central heating and cooling system into a whole-house air cleaner by attracting and capturing microscopic allergens like pet dander, smoke and household dust, while also taking care of larger airborne allergens such as mould spores and pollen. For maximum performance, replace your Filtrete™ Filter seasonally (every 90 days) to ensure you and your household are breathing cleaner air.
