The Flanders KKM Series 51255.012020 Washable Permanent Filter is a heavy-duty, aluminum media filter designed for use in residential and commercial applications. These 20" x 20'' x 1" washable filters have a high dust holding capacity and low resistance to airflow. It is recommended that the filter be coated in a dust adhesive for optimum performance. The 51255.012020 filter is constructed of an aluminum mesh media with an aluminum frame. The KKM has a drain hole in three corners. Its design allows contaminants to be trapped throughout the entire filter depth and not just the surface.
Washable for repeated use, these filters can withstand repeated cleaning before they require replacement.
High Dust Holding Capacity
A high dust holding capacity extends the service life of your filter by allowing it to retain high quantities of dust before replacement.
