What Customers Are Saying
The filtration system provides high-quality, great-tasting water for many users. Most customers are satisfied with its performance and find it easy to install and maintain. The water quality is often described as better than bottled water, and the system is compact. However, some users have experienced issues such as leaks, cracks in the housing, and problems with the faucet, which can be made of cheap, plastic materials that may break or become loose over time. The flow rate may also decrease or the tank may need replacement after a few years of use.

Good system, but shorter faucet than older model
Would RecommendBought this to replace old system that wore out after many years of use. Good system, but the faucet itself was considerably shorter than the one replaced. Would prefer they kept the height of them older system.

Sad face
Had to return the system. Too noisy and would not stop “running “. The system would not pressurize. What a waste of water. The plumber said it probably was defective.

Ease of use
Would RecommendMy original system lasted over 15 years. Obviously I bought another like system. I installed new system in less than an hour and expect it will last just as long. We love it and the water tastes great.

Overall pretty good
Would RecommendLikes: horizontal filter configuration with stand, easy to follow tubing installation. Dislikes: faucet is flimsy, not a good base and seriously the worst one of the three systems I have installed. Fix this and this would be a five star review.

disappointed
Would Not RecommendI bought this a about a week ago and there was no battery included and not even a battery housing that I could buy my own battery. This was the main reason for purchasing this system because it indicated when it was time to change filters. But I already had hole drilled to match up faucet in solid surface counter top and plumber scheduled. I ended up buying test kit strips for that.

Great feeling knowing I have the cleanest water.
I am in a community that has very hard well water. I am feeling safe with my drinking water from the little faucet, I have an auto immune disease which requires me to drink a tremendous amount of water, This is also connected to my ice maker.

Terrible design and workmanship, waste of time
Would Not RecommendThis product was problematic right out of the box, it constantly disposes water to drain, even after a warranty replacement of the membrane! The shut off device is of poor design and quality. DO NOT BUY THIS PRODUCT. Whirlpool support is even worse that their product.
