If you’re looking for better filtration than those pitcher filters but don’t want to install an entire reverse osmosis system under their sink, the NU Aqua Under Sink 3/8" Single Stage Water Filter is what your household needs. Whether you want cleaner water for drinking and cooking or you’re tired of your hands and dishes feeling filmy after you wash them, this water filter removes 99.9% of harmful contaminants like lead, chlorine, and mercury without getting rid of essential minerals your body needs.


Not only is this filter highly effective in getting rid of contaminants, it’s easy to install, clean, and maintain. Unlike reverse osmosis systems that take up lots of space under your sink and can be difficult to install, this single under-sink filter only requires you to shut off the water supply to your sink, connect your existing water line into this filter, mount, and turn your water back on- that’s it! And unlike other water filters that require an entirely new faucet or unit (like a box filter or a pitcher), this pure, healthy drinking water comes right out of your existing faucet.


Simple to install and easy to maintain, the NU Aqua Undersink 3/8" Single Stage Water Filter will give any sink in your home the clean, filtered water you need on demand. No extra faucets to install, no drilling into pipes or adding complicated hoses under your sink: just a simple filter and clean water on demand.

Great tasting water

I installed this system about 4 months ago and my entire family of 4 have been very pleased. The system did not affect our water flow at all and can easily keep up with our drinking water demands.

Easy installation

Purchased this system about 1 month ago and was pleasantly surprised. The installation was a breeze, the quality of the components was top notch and my water tastes great!

Best tap water filter

Transformed my kitchen faucet.

Dropped the lead percentage drastically

I bought this filter because we did a lead test and foud our water to have very high levels. After installing this filter it lead was undectable in our water.

Works perfectly!

I've used pitcher filters and other countertop style filters before. This system was so easy to install and the water quality and taste was much better than other systems I've tried.
