FlexFilters™

Explore our 17 Flex Filters, designed to expand and fit multiple HVAC sizes, making it easy to find the perfect fit for your system. Each filter style is available in two versions—MERV 11 and MERV 13—so you can choose the right level of filtration for your needs. MERV 11 effectively captures common particles like dust, pollen, and mold spores, providing reliable everyday air quality. For even greater protection, MERV 13 offers advanced filtration, capturing finer particles such as smoke, pet dander, and airborne bacteria—ideal for homes with allergies, pets, or anyone seeking enhanced air purity. Finding the perfect filter is simple.

Browse now to see how Flex Filters adapt to your system, ensuring efficient performance and cleaner air.
