[Protect Your Family and Household Appliance from Chlorine, Heavy Metal, and Other Harmful Chemicals] FG25B-KS 20” x 4.5” compound filter is designed to remove chlorine, lead, mercury, hydrogen sulfide, heavy metals, pesticides, herbicides, odors, and other contaminants.

[Standard Size] 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 installation.

[Built to Last] Your filter changing schedule will be based on the contamination level of your source water. We recommend changing your filters every 10-12 months or when you’ve filtered up to 150K gallons of water. Our filter cartridges are hassle-free and replacement is a breeze!

[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, this filter DOES 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.
