Our review is 5 stars

We love the product and the taste of the water is excellent. I'm sure we're are consuming 100% pure filtered water.

Easy and effective

Simple to install, fits under even a small sink, and the water tastes fully clean. Slows the flow a bit, but not at all too slow to quickly fill up whatever needs filtered water.

Fabulous filter

Took my husband about 5 minutes to install the filter. Love knowing my tap water is safe to drink and washing veggies and fruit using pure water is very comforting. No more chlorine smell! Already had the pitcher and now the under the counter filter system. Thank you!

The best!

Extremely easy to install and replace! And the company is extremely friendly and responsive in case you have questions. It goes without saying that the quality of water that the filters yield is top notch. 100% recommend it.
