What the best indoor air filter? FlexFilter is because it’s flexible, expanding to accommodate most media air cleaner cabinets. The patent pending FlexFilter ships completely collapsed into a space approximately 5” x 5” x 20”. On the job, it quickly “flexes” or expands to 16” or 20”, depending on the dimensions of the media being replaced. The entire process takes only seconds, so the contractor can change the filter quickly and move on to the next phase of the service call.

FlexFilter is easy for the distributor to stock and display, plus the filters are color coded for easy selection by the contractor. Fill out the form to get a FlexFilter merchandiser display.
