Medium Filter

A box-type medium filter that removes fine dust passing the pre-filter in HVAC systems. Its large media area gives high dust-holding capacity and low pressure drop, serving as a final filter for general HVAC or pre-treatment for HEPA. Efficiency is graded 65/85/95% by the ASHRAE 52.1 dust-spot method. Header and bag (pocket) types are also produced in the same medium range.
