How it Works

Mechanical Air Filters


Mechanical air filters (also called Media Air Filters) use filter media to remove particles from the air stream in HVAC systems.  Filter media, at the microscopic level, consists of an interlocking network of fibers that appear quite porous. This porosity is necessary to allow air to pass through the unit with minimal pressure drop. The interlocking fibers of the material form a web that captures particles in the air stream. 

Mechanical air filters are typically found next to your furnace in your home.
