Filtrete 12x36x1 AC Furnace Air Filter – MERV 8, MPR 700, 4-Pack

Upgrade your home's air quality with Filtrete 12x36x1 AC Furnace Filter

In a home that runs like a well‑oiled machine, clean air matters as much as steady airflow. The Filtrete 12x36x1 AC Furnace Filter is a four‑pack of pleated, electrostatically charged filters designed to work with most HVAC systems. With an actual size of 11.69 x 35.69 x 0.81 inches, these filters fit common 12x36 in housings while inviting cleaner air to pass through your ducts. The MPR 700 rating aligns with a solid MERV 8 filtration level, targeting a broad range of everyday indoor particles without hindering airflow.

As your system pulls air through the filter, the electrostatic charge helps attract and trap lint, pollen, dust, and pet dander, reducing the amount that circulates back into living spaces. The Filtrete 3‑in‑1 technology blends thorough particle capture with steady airflow, so your furnace or air conditioner can operate efficiently while you enjoy a calmer, fresher environment.
