This Aquasana Claryum 3 Stage Under Counter Water Filter is third-party certified by NSF, has easy filter changes, and the filter alerts you when it's time to change filters!

The Claryum® 3-Stage instantly transforms your ordinary tap water into clean, great-tasting water for 600 gallons or up to 6 months. The Claryum® 3-Stage includes a Pre-Filter to extend the life of your system, improve effectiveness, and increase performance.

Aquasana’s Claryum® filtration technology is tested and certified to NSF/ANSI Standards 42, 53 (includes P473), and 401, for the reduction of over 97% of chlorine and chloramines, 99% of microplastics and lead, and 96% of PFOA/PFOS.

It’s also certified to reduce mercury, chlorine-resistant cysts, herbicides, pesticides, VOCs, pharmaceuticals, and more. In all, it tackles 15X more contaminants than the leading pitcher filter.

Claryum®’s selective filtration technology retains naturally occurring beneficial minerals found in water like calcium, potassium, and magnesium for healthier, more delicious water.

This system combines a 20 micron Pre-Filter with activated and catalytic carbon with ion-exchange for premium water filtration. These filters are intelligently designed with the environment in mind, with minimal disposable plastic parts for reduced plastic waste.

No more guessing when you need to replace your old filters. The Claryum® 3-Stage alerts you when it’s time to change your filters. Filter replacements are engineered for the easiest replacement. No need to disconnect hoses or water lines - simply twist off and replace.

The included all-metal dedicated faucet comes in three finishes – Brushed Nickel, Chrome, and Oil Rubbed Bronze.

Requires plumber or handy homeowner with plumbing skills. It's about a one-hour installation job and requires very little space under your kitchen sink.

Long lasting filter life (6 months).

Made in the USA.
