    The middle filter does not work in my standard housing. It lets littlw to no water get by and had me chasing my tail trying to figure out why I would loose all pressure. Will never buy this set again

    Great price. The blue top carbon filter (2nd stage) top hole was too small for my system though. I have a standard 5 stage i-spring system, and the standard housing bits seem to take a ~1 1/16 filter hole. The hole in the blue housing was only abut 15/16. I had to drill it out with a forstener bit, and then it fit fine.

Sediment Filtration

  • This RO filter replacement reduces: Sand, Dirt, Silt, Dust, Scale, Rust, and other sediments
  • Pleated high capacity design captures more impurities than other replacement filters
  • Made with precision packed 100% pure food-grade polypropylene microfiber
  • Fast 1 GPM filtration
  • Multi-Layered Smart RO Filter: Made with 4 distinct layers. The outer layers catch the coarsest particles, and the inner layers catch finer particles. This means your reverse osmosis replacement filter lasts longer, catching more sediments before it needs to be replaced

Carbon Filtration
  • Captures more impurities than other Carbon filters with efficient laboratory vacuum heated carbon granules from cleaned coconut husks
  • GAC filter and ACB: Precision thermal bonded cap with industrial sealed silicon ring prevents leaks
  • High rejection rate of: Chlorine, Volatile Organic Chemicals, Halide, and Chemicals causing bad tastes and odors
  • GAC filter and PAC: Equal Flow Technology: Efficiently arranged carbon granules create full coverage filtration which means your filter lasts longer giving you the best value in filtration
  • ACB: Efficiently packed carbon granules maximize your filtration surface area which means your filter lasts longer and filters more
