Hot Spring Spa Filter 4 Pack : Patio, Lawn & Garden Review: So far, so good! - These appear to be well made for the money, and are a perfect fit on my 2010 Hotspring Grandee. Filtration is at least as good as the OEM Tri-X filters, and flow seems to be slightly better. My original Tri-X ceramic filters lasted almost 10 years... Wait, what!?!? You read that correctly, 10 years! I was religious about chemicals, maintenance and refills. Even at the point I removed them from usage, the Tri-X filter material was still in good shape, but the end caps were deterioriating to the point where they could no longer be used. Pretty impressive kit, but they ought to be for 3X the price! By my logic, if these last 3 years or so with similar usage, I'll continue to recommend them. If not, I'll likely go back to the OEM Tri-X filters. Time will tell, but so far, so good. I'll be sure to update after a year or more. Stay tuned! Review: Great quality and fit - Bought these 4x for my Hot Springs Spa. Quality is superb, long lasting. Clean and re-use. I just power wash using only water to keep soaps out of the tub. ## Features - ➤SPECIFICATIONS:Length: 10 1/2”; Outside Diameter: 5 7/8”; Top /Bottom Opening: 1 15/16”; Filtration Area: 30 sq. ft; Filter Material: Trilobal Filtration Fabric. - ➤COMPATIBLE MODELS: PLFC-6430 Spa Filter is compatible with Watkins 31489, PWK30, Unicel C-6430, Filbur FC-3915, 73178, 73250, 71825, P/N0969601. ★NOTE: This is a compatible replacement.
