About this item

Product details

Aquasana’s Claryum® 3-Stage Max Flow under sink water filter instantly transforms ordinary tap water into clean, great-tasting water for 800 gallons or up to 6 months. This system is WQA certified to reduce up to 99.99% of 78 contaminants — 15X more than the leading pitcher filter — with a .72 GPM flow rate that’s 7X faster. Aquasana's proprietary Claryum® filtration technology is tested and certified to NSF/ANSI Standards 42, 53 (includes P473), and 401, for the reduction of 99.997% of cysts, 99.6% of microplastics and lead, 99.7% of PFAS Forever Chemicals (specifically PFOA/PFOS), 97.3% of chlorine, and 91% of chloramines. The Claryum® 3-Stage Max Flow is also certified to reduce mercury, herbicides, pesticides, pharmaceuticals, and more. This system features two powerful Claryum® filters that combine activated and catalytic carbon with ion-exchange, sub-micron filtration, and an organic adsorbent booster for premium, highly effective water filtration. Also includes a 5 micron Pre-Filter that improves effectiveness and extends the life of your system by capturing rust, sediment, and silt. Claryum®'s selective filtration technology retains naturally occurring beneficial minerals found in water like calcium, potassium, and magnesium for healthier, more delicious water. These filters are intelligently designed with the environment in mind. The Claryum® 3-Stage Max Flow utilizes minimal disposable plastic parts for reduced plastic waste, so that you can enjoy clean, filtered water, without adding unnecessary plastic waste into the environment. Each filter set replaces over 6,000 plastic water bottles for less than a tenth of the cost. Make a difference with this sustainable, eco-friendly solution. We make it easy to know when you need to replace your current water filter. The Claryum® 3-Stage Max Flow will alert you when it's time to change your filters. There is no need to disconnect hoses or water lines — simply twist off and replace with a new water filter. Includes an all-metal dedicated faucet in a Brushed Nickel finish.

Clean Water = Happy Staff

Purchased the filter for our office so that staff would feel comfortable drinking water without bringing their own filtered water in. Installation was super easy.

Happy So Far

Our new filter is working great for us. The water tastes great, the installation was easy enough. We haven't had any leak problems. The high flow is much faster than our fridge filter. We bought the oil rubbed bronze faucet, and it looks great with our existing sink faucet. The filtration system also fit well under our sink which had limited space.
