WORLD’S #1 SAND FILTER IS CONSTRUCTED OF FIBERGLASS FOR A LEVEL OF DEPENDABILITY THAT'S UNSURPASSED Triton II Side Mount Filters are the original and still the industry standard. Our unique process creates a one-piece, fiberglass-reinforced tank with UV-resistant surface finish for years of unequaled strength and durability. This unique method locks in fiberglass, preventing fibers from "blooming" under harsh conditions. Filtration engineers talk about “polishing” water. It means stripping all visible contaminants for sparkling clarity. Thanks to the patented Pentair Triton II ®, dazzling water clarity is the standard. It remains blissfully simple, requiring less maintenance than cartridge or D.E. filters. And, Triton II needs only an occasional backwashing with a simple turn of a valve for the clearest water, year after year.
