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.
