Worth knowing
Uses three 20 x 4.5 inch cartridges rather than a backwashing tank. The maker says it is designed for well water and recommends the WGB32B for city water. The iron stage is rated 50,000 gallons at 3.0 ppm iron, so that figure is used as the set's capacity; the sediment and carbon stages are rated 100,000 gallons. The maker recommends a softener first when TDS is above 300 ppm. The 15 gpm figure is the maker's peak flow. The maker gives 6 to 12 months for the replacement set; the shorter figure is recorded. The page showed $535.99 with a 15% code on Oct. 4, 2026; the $535.99 price is recorded.
