How Does The SmartFilter Work?
The filter frame is permanent and all you do is replace the “working” part of the filter, the filter material. A proper fitting filter is essential to filter your home’s air. The filter frame is patented and will slide and adjust to any fractional size needed. Included with the filter frame are 2 outside support grids that can be trimmed down to size. These support grids hold the filter material inside the filter frame so that the filter material is not “sucked” out of the frame when the unit is in operation. The filter pads just trim-to-size to fit the permanent filter frame.
