Product Description

The 3M COMPANY NDP03-4IN-4 is a Filtrete allergen reduction air filter rated at MPR 1550, designed for residential forced-air HVAC systems that accept 4-inch nominal thickness filters. The electrostatically charged media attracts and captures airborne particles including pollen, mold spores, and dust mite debris. Each filter measures 19-3/4 inches x 24-7/16 inches x 4-3/16 inches actual size, fitting nominal 20x25x4-inch filter housings. This package contains 4 filters. Rated for up to 12 months of service life per filter, this product is suited for residential HVAC maintenance by homeowners and HVAC service technicians performing seasonal filter replacements.

This filter is intended for residential forced-air heating and cooling systems that use 4-inch nominal depth filter housings, such as whole-home media cabinet filter systems. The 20x25x4 nominal size is a common fit for dedicated media filter cabinets installed inline on the return-air side of residential air handlers and furnaces. The electrostatic charge on the filter media works passively without power, capturing fine particulate throughout normal system operation. Each of the 4 filters in this package is rated for up to 12 months, providing approximately 4 years of total filter supply.
