Product Details
✓[MPP Sediment Filter] The MPP sediment pre-filter is made of premium polypropylene, which can withstand and corrosion. It has a triple-layer design, and can effectively trap dirt, sand, silt, dust, rust, and scale particles as small as 5 microns.
✓[KDF Water Filter] SimPure's GAC/KDF filters use an optimal blend of coconut shell activated carbon granules and copper-zinc alloys as the primary filtering materials. This ensures maximum removal of iron, lead, mercury, residual chlorine, and odors. When installing the KDF filter, make sure the cover with more holes faces downward.
✓[CTO Carbon Filter] The 5-micron CTO filter, made of coconut shell carbon block, follows to adsorbs up to 98% of residual chlorine, removes tastes and odors like sulfur and chlorine smell, colors, significantly improving water quality.
✓[Fits Standard 20" Water Systems and Housings] As the original replacement filter set for the SimPure DB10P-3KDF, they also fit 3 stage water filter systems and blue big 20" housings including WGB32B, WGB22B WGB12B, HB28B, BBFS-222, WH300SCGS, Geek-Pure BB-20T, BB-20B, 150233, 166201, etc.
✓[Longer Lifespan] The carbon filter has a lifespan of 3-6 months, while the sediment and KDF filter can last for 6-12 months. We recommend a water pressure of 25-90 psi and a temperature range of 41-100°F.
✓[Remember to Check the O-Ring Too!] We recommend inspecting and replacing the housing o-rings each time when changing filters to prevent leaks and optimize performance.
