|2 ratings

Key item features

  • Individually wrapped high capacity water filter replacement pack for US31-PF under sink water filtration system and CW31-PF RV water filter system.
  • The FC15-PF water filter replacement uses activated carbon fiber technology for exceptional filtration. It is SGS-tested, effectively reduces PFAS, fluoride, colloids, particulates, chlorine, and odors, providing safer, cleaner water for your home.
  • 3 pieces of 10" x 2.5" replacement filter cartridges included: 1x sediment filter, 1x CTO filter, and 1x activated carbon fiber filter.
  • Note: Please unwrap the cartridges before use. Unlike an RO membrane, this filter retains healthy minerals in your water and does not reduce Total Dissolved Solids (TDS). For TDS removal, consider our iSpring Reverse Osmosis (RO) systems.

Great Product, Great Company And A Great Value!!

Only reason I'm writing this review is that we love iSpring and want to share with others just how great their product are. This set is perfectly priced and a great value. I wanted to keep a spare set on hand so we would have them when it's time for replacement. These filters work remarkable well and we love how much safer and better tasting our water is now. Don't put off ordering a new set for your Family.. Highly recommended!!
