Unicel 7000 Series 32 sq. ft. Replacement Filter Cartridge | Coleman Spas, Artesian Spas | 7CH-322

The Unicel 7000 Series 7CH-322 delivers 32 sq. ft. of filtration area in a compact 8" x 7" OD cartridge engineered for top-load spa filter housings. With 175 precision-formed pleats of 3 oz. Reemay 2033 polyester media, it maximizes surface contact and flow-through efficiency — keeping your spa water clear between service intervals. The 2" MPT bottom thread locks in securely, while the semi-circular top handle makes pull-out removal fast and clean.

⚠️ IMPORTANT: Artesian Spas Owners — Verify Your Dimensions
The original Artesian Spas filter is 7-7/8" OD and 7-5/8" overall length. The 7CH-322 measures 7" OD and 8" length. This is a widely-used functional replacement, but please measure your existing cartridge before ordering to confirm fit in your specific spa model.

⚠️ IMPORTANT: Master Spas Eco-Pur System — Installation Note
The 7CH-322 is compatible with select Master Spas models using 7" OD Eco-Pur filter housings. For models with an 8" OD housing, the black stand pipe must be removed before installation. Always consult your spa's owner's manual to confirm compatibility and the correct installation procedure for your specific model.
