702-4 Air Filter, 20 In L, 20 In W, 8 MERV, 700 MPR, Fiberglass Frame

A Filtrete electrostatically charged pleated air filter designed to attract and trap particles such as lint, pollen, dust, and pet dander as air passes through your heating and cooling system. Unlike ordinary non-electrostatic filters, this filter's unique electrostatic design works harder to capture unwanted particles with each cycle, helping you maintain cleaner indoor air for your home.

A dirty or clogged air filter slows down airflow and forces your heating and cooling system to work harder, wasting energy and reducing comfort. Regular filter changes every 90 days (for 1-inch filters) help your HVAC system operate efficiently, maintain consistent temperature control, and remove microscopic allergens from your circulation.

Features and Benefits

• Electrostatic Technology: Exclusive Filtrete Brand 3-in-1 technology from 3M attracts and traps more airborne particles than fiberglass, washable, or non-electrostatic filters.
• High MPR Rating: 700 MPR rating (MERV 8) captures microparticles including pollen, pet dander, smoke, and dust from the air passing through.
• Pleated Construction: Designed to trap unwanted air particles while letting cleaner air flow through your system.
• Easy Replacement: Standard 1-inch depth fits most residential furnace, air conditioner, and HVAC systems; change every 90 days for optimal performance.
• Smart Reminders: Use the Filtrete smart app to scan your filter's barcode and set replacement reminders at 30, 60, or 90 days.
