Filter Hut's whole house air cleaner filters are specifically designed to replace the original brand filters and be installed in OEM air cleaner housings. They are MERV rated to independent ASHRAE standards to ensure they will perform as good or better than the original filters. These filters are a pleated design that combines a larger surface area with maximum air flow, allowing for reduced energy costs.
