The DFS replacement for the Aprilaire 213 filter is specifically designed to fit Aprilaire whole-house air purifier models 1210, 1620, 2210, 2216, 3210, 4200, Space-Gard 2200, and other systems that accept the OEM Aprilaire 213 media. It slides directly into the existing filter cabinet without modification, giving you a true drop-in replacement for MERV 13 media slots.

This DFS replacement carries a MERV 13 rating, capturing particles as small as 0.3–1.0 microns. It effectively traps fine dust, pollen, pet dander, mold spores, smoke, bacteria, and virus-carrying particles, making it ideal for households with allergy sufferers or anyone seeking enhanced indoor air quality on par with the original Aprilaire 213.

For optimal performance in Aprilaire whole-house systems, this filter should be replaced approximately every 12 months under normal residential use. Homes with pets, smokers, renovation dust, or occupants with respiratory conditions may need replacement every 6–9 months. The deep-pleated media is engineered for a full year of airflow efficiency without premature pressure drop.

Yes. This DFS filter features the same patented-style self-sealing side panels as the Aprilaire 213, which expand inside the air cleaner cabinet to block air bypass. This ensures 100% of the conditioned air passes through the MERV 13 media rather than leaking around the filter, maintaining the rated efficiency throughout its service life.

The filter measures 20" x 25" x 4" (actual dimensions approximately 20" x 26" x 4") to match the Aprilaire 213 specifications precisely. The deep 4-inch pleated design provides greater surface area than a standard 1-inch filter, allowing for lower airflow resistance and a significantly longer service life in compatible Aprilaire air cleaners.
