The Aquasana SmartFlow® Reverse Osmosis System delivers exceptionally pure, great-tasting water straight from your kitchen tap, using WQA-certified technology that removes the contaminants conventional filters miss. Certified to NSF/ANSI Standards 42, 53, 58, and 401, this RO system reduces up to 99.99 percent of 90 harmful contaminants, including fluoride, PFAS, arsenic, lead, chromium 6, pharmaceuticals, microplastics, asbestos, mercury, chlorine, and TDS. It is one of the most comprehensive home filtration systems available, giving your family clean drinking water with total peace of mind.

Powered by patented SmartFlow® Technology, the system uses an ultra-efficient RO membrane that produces more purified water with less waste. The long-lasting filters minimize maintenance and keep performance strong, so you can enjoy better water without constant replacements.

To improve taste and hydration, the SmartFlow® system includes a built-in Remineralizer. This final filtration stage restores essential minerals like calcium and magnesium, giving you water that tastes crisp and naturally balanced rather than flat or processed.

Filter changes are quick and convenient. Simply twist out the old cartridges and replace them with Aquasana-certified filters that deliver ongoing contaminant removal. Each filter set replaces over 2,750 plastic water bottles, helping you reduce waste while supporting your household’s health.

Your system arrives with everything needed for under-counter installation, including the first set of filters, the RO membrane, storage tank, chrome faucet, and required fittings. It also includes a two-year limited warranty. Professional installation is recommended, and Aquasana’s support team is available at 866-662-6885 for assistance.
