Purolator AG5039510285A 20x30x2 Panel Air Filter Merv 4

Product Description

The PUROLATOR AG5039510285A is a disposable panel air filter built for forced-air HVAC systems in residential, commercial, and light industrial applications. It uses a synthetic polyester media to capture airborne particulates at a MERV 4 rating, delivering 85 to 90 percent filtration efficiency. The filter operates at a face velocity of 300 feet per minute, with an initial resistance of 0.19 inches water gauge and a final resistance of 1.0 inch water gauge. Rated for continuous use up to 200 degrees F, it meets UL standards. The kraft frame with green and white media construction holds its shape through the full service cycle without collapsing or bypassing.

This filter fits standard 20x30x2 inch filter slots and is suited for rooftop units, air handlers, and furnace returns in residential homes, commercial offices, and light industrial facilities. The disposable design eliminates washing or reconditioning — remove and replace on a scheduled maintenance interval. It is a practical choice for pre-filtration stages or applications where lower-cost, routine filter replacement is the preferred service model.
