About This Item
The Unicel 4CH-24 is a 4000 Series 25 sq. ft. replacement spa filter cartridge engineered for top-load filter housings that use a 1-1/2" male pipe thread (MPT) bottom connection. With 173 pleats of 3 oz. Reemay 2033 polyester media packed into a compact 9 3/4" body, this cartridge delivers exceptional dirt-holding capacity and water clarity in spa and hot tub applications.
⚠️ IMPORTANT: Dream Maker Spa Owners — Read Before Installing
Some Dream Maker spa skimmers include a "pad adaptor" installed at the suction fitting. This adaptor must be removed before installing the 4CH-24. With the adaptor removed, the cartridge's MPT fitting threads directly into the suction fitting for a proper, leak-free seal.
