Ultra Aire 4037722 Merv 13 Dehumidifier Filter

Product Description

The ULTRA AIRE 4037722 is a MERV 13 replacement filter designed for use with compatible Ultra Aire whole-home dehumidifiers. It captures airborne particles down to 0.3 microns, achieving 90% ASHRAE Dust Spot efficiency. At 14 inches x 17.5 inches x 1.75 inches, this filter fits directly into the dehumidifier filter housing without modification. HVAC technicians and indoor air quality professionals install this filter as part of routine dehumidifier maintenance to maintain system airflow and filtration performance. It is the correct factory-specified filter for systems that call for a MERV 13 media in this frame size.

This filter is suited for residential whole-home dehumidification systems where indoor air quality and humidity control are managed together. It is typically installed in finished basements, crawlspace-fed systems, or central ducted dehumidifier applications. Replacing the filter on schedule maintains rated airflow across the dehumidifier coil, preventing efficiency loss and coil fouling. This is a standard scheduled-maintenance item for service technicians managing dehumidifier contracts or whole-home IAQ systems.

Installation Notes

Filter replacement is a routine maintenance task performed by HVAC technicians or qualified service professionals. Before servicing, power down the dehumidifier unit at the disconnect or breaker. Slide the old filter out, note the airflow direction arrow on the filter frame, and insert the new filter with the arrow oriented correctly. Dispose of the used filter per local waste guidelines and log the replacement date for service records.
