Extended handling time.

The MECH 8 is built with a 3/8" undercut on the length and width, and 1/8" undercut thickness, as is standard for filter sizing.

The Mech-8 media is now specially formulated to inactivate the SARS-CoV-2 (COVID 19) viral particles that come in contact with the filter. This media has been tested in Microbac Laboratories which is a leading independent testing laboratory and the global leader in SARS-CoV-2 testing with regulatory approved protocols. This media demonstrated a 99.99% inactivation of SARS-CoV-2 viral particles captured in the media. Along with antimicrobial coating that is applied to prevent bacteria and mold growth on the filter.

The Mech 8 is the highest rated mechanical washable filter available. It has been independently tested at MERV 8. The pressure drop is rated at .14” w.g. at 1180 cfm. What separates this filter from the other washable filters is it uses mechanical filtration instead of electrostatic.

A note about washable filter frame thickness:

All washable filters have the same amount of filtering media no matter the thickness of the filter frame. The frames are available in many sizes to allow users to install the filter into varying widths of tracks, slots, grilles, etc. This eliminates the need for modification of the track/slot/grille/etc. when switching from one type of filter to another, i.e. switching from a 2" thick pleated filter to a washable filter. All washable filters must be washed monthly; so they are made with enough media to work as designed and allow for proper dust holding capacity until the monthly wash is required. A thicker frame on a washable filter does not contain more media nor is the media doubled up or thicker in any way. The advertised efficiency and air flow remains the same throughout all thicknesses of washable filters in each of their respective LxW dimensions. In filtration, the efficiency is the particle size a filter will capture. 

Due to possible materials shortages and unforeseen events, by ordering you consent to any handling time for any size.
