Elevate your indoor air with Filtrete 16x25x4 AC Furnace Filter

Designed by 3M, the Filtrete 16x25x4 MPR 700 filter blends filtration power with clean airflow. Built on exclusive Filtrete 3-in-1 technology, this filter pulls in and traps particles while letting cleaner air pass through. With an MPR 700 paired with a MERV 8 rating, it targets common household irritants such as pollen and pet dander, and it also captures larger debris like lint and dust mite debris. The result is a filter that supports a fresher-feeling home environment without compromising airflow.

Exact sizing matters for proper fit: the true dimensions are 15.88 in x 24.56 in x 4.31 in. This model is designed to fit Lennox and Honeywell media air cleaners, helping you install with confidence. It’s offered as a 2-pack for convenient replacements, and it’s intended for up to 12 months of typical use in standard home HVAC systems. Pairing compatibility, a precise size, and a year-long up-time window makes this Filtrete filter a practical choice for ongoing maintenance.
