{"product_id":"unicel-6ch-502","title":"Unicel 6CH-502 Filter for Artesian Spas New Artesian 6\" D (2\" MPT) | 50 Sq. Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel 6CH-502 is a pleated polyester spa cartridge filter element providing 50.0 sq ft of filtration area in a 6-inch outer diameter form factor with an integrated 2-inch MPT (male pipe thread) bottom fitting for direct threaded installation into compatible Artesian Spas manifold seats. Construction features Reemay nonwoven polyester media with a nominal 20-micron filtration rating, ABS injection-molded end caps, and a reinforced threaded base molded to ANSI 2-inch MPT specification for leak-free engagement against the housing seat. The threaded-base configuration eliminates the need for a separate standpipe assembly, reducing potential bypass paths and simplifying tech-level cartridge exchange. The element is rated for continuous spa service at temperatures up to 104°F with intermittent excursions to 120°F, supporting the operating pressure range typical of residential spa circulation pumps (5–15 PSI).\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: rinse with fresh water every 2–4 weeks; chemical soak (dilute TSP or enzyme cleaner) every 4–6 weeks to remove body oils, lotions, and surfactants that resist water rinsing. Replace at ≤ 12-month intervals under normal residential spa use, or at ΔP ≥ 5 PSI above clean baseline, whichever occurs first. Installation: hand-tighten the cartridge base into the 2\" MPT manifold seat — do not use pipe wrench or strap wrench, as overtorque can crack the ABS threaded base; PTFE tape is not required and not recommended for this seat geometry. Chemical compatibility: polyester fabric and ABS end cap construction tolerate continuous service at ≤ 10 ppm free available chlorine or ≤ 30 ppm total bromine; muriatic acid soak at 1:20 dilution compatible for calcium scale removal (20 minutes maximum exposure, rinse thoroughly before reinstallation). Enzyme cleaners compatible without restriction. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eYour order includes the selected quantity of replacement spa filter cartridges.
