Aprilaire 110 Replacement Filter for AprilAire 1110 — MERV 11, 16 x 20 x 4, Pack of 1 | Genuine USA-Made

Keep indoor air clean with a genuine Aprilaire replacement filter

The Aprilaire 110 Healthy Air 11 Filter is designed to work with your AprilAire Air Cleaner Model 1110. With a MERV 11 rating, this replacement filter targets a broad range of common airborne particles as air passes through, helping to keep your living spaces looking and feeling fresher. While you won’t notice every particle with the naked eye, you may sense reduced dust settling on furniture and fewer interruptions from routine cleaning.

Made to fit precisely and perform reliably, this filter employs a four-inch design that delivers more filter media than typical 1-inch filters. The result is a larger surface area that can capture dust, pollen, mold spores, bacteria, and pet dander, potentially supporting a steady flow of conditioned air through your system. Genuine Aprilaire filters are engineered to align with your equipment’s specifications, and this model comes with the Pure Fit Promise for a precise fit.
