Transform your tap water into ultra-delicious, healthy water with Aquasana — your solution for clean, great-tasting water in every sip. Tested and certified by the Water Quality Association (WQA), Aquasana’s RO system meets NSF/ANSI standards 42, 53, 58, 401, and CSA B483.1. It effectively reduces up to 99.99% of harmful contaminants including fluoride, chromium 6, TDS, microplastics, PFAS, asbestos, mercury, chlorine, pharmaceuticals, and lead. Enjoy peace of mind knowing your water is filtered to perfection. Our advanced reverse osmosis membrane technology is ultra-efficient, providing more pure water and less water waste. Our longer filter life means you can enjoy cleaner water with minimal hassle. Unlike standard RO systems, Aquasana includes a Remineralizer that restores essential minerals like calcium and magnesium, providing you with healthier, better-tasting water. Replacing your filters has never been easier. Simply twist out the old cartridge and replace it with an Aquasana certified replacement filter for ongoing contaminant removal. Each set of filters replaces the equivalent of 2,750+ plastic water bottles. This system includes the first set of filters, RO membrane, RO tank, parts required for under countertop installation, and a 2-year limited warranty. Choose one of our other configurations if you need a faucet or use your own dedicated filtered-water fixture. Professional installation recommended. Aquasana support is available at 866-662-6885. Experience the Aquasana difference and bring healthier water into your home. With over 25 years of innovation, our U.S.-based scientists and engineers design filters for maximum contaminant removal, backed by performance data sheets and certifications from NSF, IAPMO, and WQA.
