Aprilaire 210 Merv 11 Air Filter 20x25x4 Replacement

Product Description

The APRILAIRE 210 is a MERV 11 synthetic fiber air filter designed as a direct replacement media pad for Aprilaire whole-house air purifiers. Rated at MERV 11, this filter captures a broad range of airborne contaminants including dust, dander, mold spores, pollen, dust mites, and smoke particles. With nominal dimensions of 20 inches high by 25 inches wide by 4 inches deep and actual measurements of 20.6 inches high by 26.63 inches wide by 4 inches deep, it fits the filter cabinet without modification. Licensed HVAC technicians and trained service professionals handle installation during routine annual maintenance cycles.

The APRILAIRE 210 is rated for use in residential and light-commercial whole-house air purification systems. It is engineered for installations where a media-style bypass filter is integrated into the main duct system, providing whole-home filtration without requiring a standalone air handler accessory. Compatible units include models 1210, 1620, 2210, 2216, 3210, 4200, UV12, and UV22. With the addition of Upgrade Kit 1213, the filter also fits the 2120, 2200 Aprilaire, and 2200 Space-Gard air purifiers. Aprilaire recommends replacing this filter on a 12-month schedule under normal operating conditions.

Before replacing the filter media, shut down the air handler and confirm the system is de-energized at the disconnect or breaker. Slide the existing media pad out of the cabinet track, insert the new filter with airflow direction arrows oriented correctly per the cabinet label, and reseal the access door before restoring power. Dispose of the used filter in accordance with local waste guidelines.
