About This

  • [Protect Your Family and Household Appliance from Chlorine, Heavy Metal, and Other Harmful Chemicals] Our filter (FG25B-KS) is specially designed to remove chlorine, lead, mercury, hydrogen sulfide, heavy metals, pesticides, herbicides, odors, and other contaminants.
  • [Easy Filter Replacement] Refer to our manual and our helpful YouTube videos for easy filter replacement. Water flow: up to 15 GPM. Our filter set fits any standard whole house water filter housings that require 20” x 4.5” cartridges. Each cartridge is individually wrapped to ensure that the filter stays fresh. Please unwrap the cartridges before filter replacement.
  • [Built to Last] The first stage polypropylene sediment filter is able to filter particles as small as 5 microns. The third stage CTO Carbon Block filter is made of quality coconut shell carbon. Each filter is tested by an independent third-party to meet NSF/ANSI standards. Both filters have a capacity of 100,000 gallons of water; enough to supply a family of four with clean water for a full year.
  • [Peace-of-Mind Customer Service] We offer both technical assistance and customer service support by phone or email out of our headquarters in Atlanta, GA. Our knowledgeable team is available to help you find a filtration solution that best solves your specific water concerns or to help with any after-sale support you may need. Our goal is, and always will be, to maximize your user experience.
  • [Please Note] Unlike an RO membrane, these filters DO NOT reduce Total Dissolved Solids (TDS). Instead this filter keeps healthy minerals in your water while removing harmful chemicals. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
