704-4 Air Filter, 14 In L, 25 In W, 12 Merv, 700 Mpr, Cardboard Frame

A quality home air filter makes a real difference in indoor air quality. Ordinary non-electrostatic air filters struggle to capture unwanted particles like dust, pollen, pet dander, and lint as air cycles through your heating and cooling system. The Filtrete Electrostatic Pleated Air Filter uses an electrostatically charged design that actively attracts and traps more particles from the air, helping you maintain cleaner indoor air with every cycle through your HVAC system.

With each pass, this filter works to reduce airborne irritants while maintaining proper airflow through your furnace, air conditioner, or HVAC system. A dirty filter forces your system to work harder, wasting energy and reducing comfort. Upgrading to this Filtrete filter helps your heating and cooling system operate efficiently while improving the air you breathe at home.

Features and Benefits

• Electrostatic Technology: The electrostatically charged pleated design attracts and traps more microparticles including pollen, pet dander, dust, and smoke compared to standard fiberglass and non-electrostatic filters.
• 3-in-1 Technology: Filtrete's exclusive 3-in-1 design from 3M traps unwanted air particles while maintaining healthy airflow through your system.
• High Efficiency Rating: With a 700 MPR rating (equivalent to MERV 8), this filter captures more microparticles than basic filters, with higher MPR ratings capturing progressively more contaminants.
• Easy Replacement: Standard 1-inch pleated format fits most residential HVAC systems; recommended replacement every 90 days for optimal performance.
• Energy Savings: Keeping airflow unrestricted helps your heating and cooling system run efficiently, reducing wasted energy.
