## Overview

The AO Smith Under Sink Water Filter System uses advanced 2-stage Claryum filtration to reduce up to 99% of 77 harmful contaminants including lead, PFAS, chlorine, and more. Certified to NSF standards 42, 53, 401 + P473, it delivers a steady 0.5 gallons per minute flow rate without wasting water or adding chemicals. Designed for easy under-counter installation, this battery-powered system offers up to 500 gallons or 6 months of clean, great-tasting water, making it an essential upgrade for health-conscious kitchens.

## Description

Connects with included tee to your 3/8 inch threaded cold water supply line to an additional faucet included with the system. Only takes a few minutes. Includes tubing needed for installation - no plumber required.

Review: These filters are great! I just installed my second one. There was nothing wrong with the first one, bit the plumbing has to be replaced after 5 years. Mine was pushing 6 years and I didn't want to risk broken lines. Installing it is really easy and takes about an hour depending on space and if you have basic plumbing skills. Filter replacement takes 5 minutes.
Review: After more than twenty years of having 5 gallon bottles of spring water delivered, the water started to have a strange taste/odor, so I canceled my delivery service and started looking for alternatives and the New York Times Wirecutter review recommended this one for removal of chlorine, plastics, and metals at a low price. Installation was straightforward (although I wish the lettered parts were included in the numbered diagram) and immediately after the recommended 10 minute flush out period my tap water, which is not horrible but has a chlorine taste, tasted great. I plan to fill a 3 gallon glass water cooler bottle with this filtered water to use with my existing cooler so I always have cold and hot water available as usual. My yearly cost for drinking water will be reduced by about 70% once I factor in the cost of replacing the filters every six months. Highly recommend!
