Product Description

The 3M COMPANY NADP01-4IN-4 is a Filtrete Allergen Reduction Deep Pleat air filter rated at 1000 MPR, designed for forced-air HVAC systems in residential and light-commercial applications. The deep pleat construction measures 16 inches by 25 inches by 4 inches, providing an extended media surface area that supports longer service intervals compared to standard 1-inch filters. This 4-pack is sold as a single unit of measure (EA) at a package quantity of 4. Licensed HVAC technicians and knowledgeable homeowners performing filter maintenance will find the 1000 MPR rating effective for reducing common airborne allergens including dust, pollen, and pet dander.

This filter is intended for use in residential forced-air furnaces, air handlers, and central air conditioning systems that accept a 16 x 25 x 4 inch filter slot. The deep pleat 4-inch depth is commonly found in media cabinet housings and certain OEM filter cabinets installed in line with the return-air duct. The 1000 MPR performance tier makes it a practical choice for households with allergy concerns where higher filtration efficiency is needed without the airflow restriction of top-tier MERV-rated media.

Always shut down the furnace or air handler at the equipment disconnect or thermostat before opening the filter cabinet.
