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.

Spend your money on a better system
Would Not RecommendAfter months of use i can honestly say this system is terrible. I now have to shut off my water to keep my system from draining constantly. My system pressure is at the recommended PSI and even the take it running it proper psi but still just keeps draining. Find a better system then this one. If you do contact whirlpool because you did register it, they just send you the same crap parts.
Perfect small RO water system
Would RecommendThis RO system seems to work well and everything is included to connect under the sink if you have standard 3/8 compression water stops/supply lines. Minimal additional tools are needed, just a couple wrenches, drill and drill bits or step bit. Everything seemed to be of good quality and the various colored lines provided can be trimmed easily for a tidy installation. The water this system provides has near zero TDS or total dissolved solids (calcium, iron etc) and works very well.

You must have strong hands to remove filters.
Would Not RecommendInstallation instructions are awful. They leave out parts of the instructions and then you have to call Whirlpool. No instruction about tanks pressure. Almost impossible to get filters out. Doesn’t store much water in tanks.

Previous systems work flawlessly this one was an open box and was probably returned to the store for similar problems. In the end, that’s what I did and bought a similar product online, which works perfectly. It’s the same system just under a different brand name. I like the new filter and I’d like the ones before this, b...

Reliable and trustworthy
Would RecommendPeace of Mind that the quality of water is safe. Just because you have a well or on county water doesn't mean your water is clean for drinking without boiling. Saves your appliances that require water to avoid scaling too!
Very good value, Store availability was a comfort
Ease of setup, Instructions were clear and easy to follow.
