Review: Perfect - Perfect fit and great price
Review: GREAT filters, but they don’t last 6 months with bad water - These filters do an amazing job at cleaning up nasty well water!!! Just know that if you have really bad well water, they won’t last 6 months. Mine lasted 2 months and that is with a 40 micron spin down filter on the system prior to these filters! After 2 months, I saw 45 psi of water pressure coming into the first filter, and 10 psi of water pressure coming out of the last filter! Even with the filters clogged up this badly, they still filtered the water really good though!! I 100% recommend these filters to others, and I have done so!

## Features

- [Protects Home Appliances] SimPure 4.5 x 20 water filter set combines the best of sediment reduction, chlorine, and odor removal, and filters water for the whole home. Protects the water softener and home appliances. You can also use them with an inline sediment filter to filter well water or rainwater.
- [Fits Standard 20" Water Systems and Housings] As the original replacement filter set for the SimPure DB10P-3, they also fit 3 stage water filter systems and clear or blue big 20" housings including WGB32B, WGB22B WGB12B, HB28B, BBFS-222, WH300SCGS, Geek-Pure BB-20T, BB-20B, 150233, 166201, etc.
- [High Flow Rate and Long Service Life]This 20-inch water filter cartridge provides a large filtration area and high flow rate of up to 12 GPM. With a service life of up to 40,000 gallons, it saves you time and replacement costs. For optimum performance, we recommend changing the filter every 6-12 months based on your water conditions.
- [MPP Sediment Filter]The MPP sediment pre-filter is made of premium polypropylene, which can withstand corrosion. It has a triple-layer design, and can effectively trap dirt, sand, silt, dust, rust, and scale particles as small as 5 microns.
- [GAC & CTO Carbon Filter]The premium GAC water filter with highly adsorbent coconut shell carbon densely packed for optimal chlorine reduction with lower pressure loss. The 5-micron CTO carbon block filter cartridge follows to polish water by further absorbing tastes and odors, and fine particles for further finishing.
- [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.
