Ruud PD540042 Replacement Filter Media Merv 8 21x21x5 in

Product Description

The RUUD PD540042 is a MERV 8 replacement filter media cartridge designed for use with RUUD UXHF-E21M13 media air cleaners. Measuring 21 x 21 x 5 inches, this filter uses finger-supported vertical pleats that stay evenly spaced to maximize dirt-holding capacity while keeping pressure drop to a minimum. A factory-installed double gasket runs along the top and bottom edges to eliminate filter bypass. The galvanized, rust-resistant wire mesh frame supports the media and holds pleat shape even under heavy dust load. Moisture-resistant frame construction retains its shape and structural integrity in high-humidity environments. This is an OEM-style replacement installed by HVAC technicians during scheduled maintenance intervals.

This filter media is designed for the XHF and XGF series media air cleaners. It is suitable for all forced-air HVAC configurations including residential and light commercial systems. The UXHF-E21M13 media air cleaner is the primary application for this replacement cartridge. MERV 8 filtration captures a broad range of common airborne particulates including dust, pollen, mold spores, and lint, making it appropriate for standard residential and commercial IAQ maintenance programs.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler or furnace at the disconnect or breaker before accessing the filter cabinet. Confirm the replacement media is seated fully against the cabinet frame and that the double gasket makes complete contact on all edges to prevent bypass. Follow the equipment manufacturer's recommended maintenance schedule for filter replacement intervals.
