The AprilAire 413 is the genuine OEM replacement filter for AprilAire 1410, 1610, 2410, and 4400 whole-house air purifiers. MERV 13 efficiency captures allergens, pollen, mold spores, bacteria, and smoke at the residential scale.
The 16x25x4 size fits the smaller AprilAire chassis classes — typical for homes under 2,500 square feet. Genuine OEM construction prevents the bypass leakage common in third-party filters cut to fit.
AprilAire has manufactured HVAC air quality products in Madison, Wisconsin since 1954.
