Conventional Filter Type 12 (4CH-21)

removable hot tub filter bezelNote : If replacing an old Pleatco brand threaded filter cartridge, be aware that these have a removable male pipe thread fitting which slip-fits into a hole in the bottom of the filter. You may need to unscrew the pipe fitting from your spa's filter housing if it did not come out with the old filter (many spa owners are not even aware that the fitting is still in there) before you can screw in your new filter.

The filters that we sell are moulded as a single piece, so that the threaded fitting always comes out of the spa with the filter.
