Nordic Pure 20x25x5HM10-4 Merv 10 Air Filter 4 Pack

Product Description

The NORDIC PURE 20x25x5HM10-4 is a MERV 10 pleated air filter designed for residential forced-air heating and cooling systems that use a deep-media filter housing. The nominal size is 20x25x5 inches with an actual size of 19.88 x 24.88 x 4.38 inches, making it compatible with housings sized for a 4 3/8 inch depth filter. The filter media is hypoallergenic, antimicrobial, and electrostatic, bonded to a metal mesh support grid for structural integrity. The frame is constructed from moisture-resistant beverage board. This SKU ships as a 4-pack and is manufactured in the USA. Licensed HVAC technicians and experienced DIYers install this filter during routine maintenance intervals.

This filter fits deep-media housings found in residential HVAC systems that accept a nominal 20x25x5 filter with a 4 3/8 inch actual depth. It is rated as a direct replacement for Honeywell 20x25x4 deep-media filters and serves as a compatible replacement for Lennox, Carrier, and Bryant systems using the same housing dimensions. MERV 10 performance is equivalent to an MPR 1000 rating. Always verify the actual filter or housing dimensions before ordering, as nominal and actual sizes vary by manufacturer, especially across the 4 inch to 5 inch depth range.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified DIYer. Power down the air handler or furnace at the disconnect or breaker before accessing the filter housing. Confirm airflow direction marked on the filter frame aligns with the direction of airflow in the system before seating the filter. Nordic Pure recommends replacing this filter every 3 to 6 months under normal operating conditions, or more frequently during home renovation or high-dust periods.
