About This Protect Your Family and Household Appliances from Chlorine, Heavy Metals, and Other Harmful Chemicals: The FG25-KS 20” x 2.5” compound filter is designed to remove chlorine, lead, mercury, hydrogen sulfide, chloramine, PFAS, heavy metals, herbicides, odors, and other contaminants. Standard Size: Our filter fits any standard whole house water filter housings that require 20” x 2.5” 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 depend on the contamination level of your source water. We recommend changing your filters every 6 months or after filtering up to 50,000 gallons of water. Peace-of-Mind Customer Service: We offer both technical assistance and customer service support by phone or email from our headquarters in Atlanta, GA. Our knowledgeable team is available to help you find the best filtration solution for your specific water concerns or to assist with any after-sale support you may need. Our goal is to maximize your user experience. Please Note: Unlike an RO membrane, this filter does not reduce Total Dissolved Solids (TDS). Instead, it 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.
