3M Company 700-4 Electrostatic Air Filter 700 Mpr 16x20x1

Product Description

The 3M COMPANY 700-4 is a Filtrete electrostatic air filter rated at 700 MPR, designed for forced-air residential HVAC systems. Sold as a 4-pack, each filter measures 16 inches by 20 inches by 1 inch and fits standard 1-inch filter slots in furnaces and air handlers. The 700 MPR rating indicates the filter captures lint, dust, mite debris, and pollen-size particles while maintaining adequate airflow through typical residential equipment. HVAC technicians and homeowners install this filter as a routine maintenance item during seasonal service calls.

This filter is intended for use in residential forced-air heating and cooling systems that accept a 16x20x1 inch filter. It is a common size found in a wide range of gas furnaces, heat pumps, and central air handlers with accessible filter racks. The 4-pack format is well suited for service techs stocking multiple units on a route or for property managers maintaining multiple systems on a regular replacement schedule.
