The Smith Filter MECH 8 MERV 8 Washable Metal Air Filter sets the standard for durable, reusable HVAC filtration. Recognized as the highest rated mechanical washable filter available, the MECH 8 delivers proven MERV 8 performance even after repeated washing—backed by independent testing.

Engineered with depth-loading mechanical media, the filter captures particles throughout its structure for extended life and consistent airflow. Each layer of media is reinforced between expanded aluminum grids and housed in a mitered, riveted aluminum frame for maximum rigidity and corrosion resistance.

An antimicrobial coating protects the filter from mold and bacterial growth, making it ideal for environments where air quality and hygiene are critical. The MECH 8 maintains a low pressure drop of 0.14 in. w.g. @ 1180 CFM, ensuring efficient system performance while reducing energy costs.

Rated for continuous use up to 180 °F (82 °C), the MECH 8 is available in 1", 2", and 4" thicknesses, in both standard and custom sizes, to fit a range of commercial and light industrial HVAC systems.
