Aprilaire 213 Replacement Filter – MERV 13 for Whole House Air Purifiers (20x25x4)

Upgrade your home's air with the Aprilaire 213 Healthy Air filter

A small change can make a noticeable difference in the air you breathe. The Aprilaire 213 replacement filter uses a high‑efficiency MERV 13 media to capture a broad range of airborne particles as air moves through your whole‑house purifier. It is designed to fit compatible Aprilaire air cleaners, delivering consistent filtration performance while your HVAC system runs.

Designed with a four‑inch depth, this filter provides a large filtration surface area. The 28 square feet of filtering media allows more space for particles to be captured, helping reduce dust buildup in living spaces and within HVAC components. With a low initial resistance, the filter can support longer intervals between changes under typical usage conditions.
