The filter media for the above "pleated" air cleaners are not available due to its special design. We have designed a filter and frame assembly to be used as a replacement for the previous 5" pleated filter media.

The new pleated filter will be a 4" filter. The use of this new thinner filter media will require a special sheet metal frame for its use in this air cleaner cabinet/casing. The frame will be a one time purchase requirement and will include the sheet metal frame and the new filter media. Subsequent changing of the filter media will require the purchase of filter media only. Click here to purchase filter media only. Part # L2-05718-1 and L2-05718-2.

Removes dust, pollen, molds, tobacco smoke, grease, soot, bacteria, animal dander, airborne dust mites, and other particle contaminants.
