**The model numbers above are provided to the best of our knowledge, however, we recommend that you physically measure your current filter to be sure it is 19-7/8 x 25-1/4 x 4-7/8.
PLEASE NOTE: As shown in the pictures, this filter consists of 2 inches of filter media in a 4-7/8 inch frame. Why not have 4-7/8 inches of filter media? One might think that the thicker the media, the better the filter. However, this filter uses electrostatic media to trap particles. The media must be compacted to a specific density for the electrostatic fibers to build static electricity and attract dust. They are not like regular paper media filters. If the media was any thicker...it would create too much air resistance.
Why spend hundreds on expensive media filters that just wind up in the landfill.
These permanent filters feature a lifetime warranty.
Replace your current MEDIA FILTERS or ELECTRONIC AIR CLEANER (EAC) CELLS with our permanent, washable filter. Our filters develop a natural electrostatic charge as air passes through them...no electricity required. Just vacuum off or hose off to release the electrostatic charge and clean the filter.
These filters have the same specs as our popular Electra9400 filters.
