Easy install, smooth taste
on January 24, 2020
Posted by: Stefano
from Sunnyvale, CA
I finished the DIY setup in about 2 hours. Had to remove an old stubborn soap dispenser, so it took longer. I turned on the tap nervously, looked under the counter, and there were no leaks! That felt like enough to recommend the product right there. After letting it run for 20 minutes as directed, I tasted the water and it was smooth. There appeared to be little white specks floating around, but they disappeared after a few seconds and I realized they were just tiny bubbles. All in all, I'm happy with it. Even with the Max Flow model the flow rate is not that fast, but it's adequate. I have no clue whether our water is any "healthier", but it's giving me and my wife some peace of mind.
Pros: Clean taste, Easy to install
I would recommend this to a friend!

We had the filter installed by a professional. The pressure was bad. The internet is full of advice on how to put a shim in this product to improve it. Perhaps just creating a good product could avoid all that.

The quality of the water is comparable to a water de-hardener system, flavor is incredibly good unlike other systems that give you clean water but with a lousy taste! "NOTE, THERE ISN'T ANY PHOTOGRAPHS OR VIDEO BECAUSE I PAYED FOR THIS ITEM!!
Pros: No odor, Clean taste, Long lasting filter, Good Water Flow, Nice faucet, Easy to install
I would recommend this to a friend!

I have had one for four years and I just bought another one. The instruction manual for assembling the filter is terrible - it should be rewritten.
Pros: No odor, Clean taste, Good Water Flow, Durable, Nice faucet
Cons: Difficult to install

Always runs out
on May 18, 2019
Posted by: the middle of no where
from New Mexico
Not sure if it’s the low pressure in our area or the system itself. Always runs out of filtered water. Can barely fill 2 people’s drinking glasses. Lucky if we can fill our keurig water container. Have to have a jug or water bottles on hand always in case RO tank doesn’t make it all the way for cooking pots etc. Pretty disappointed really
Pros: No odor, Clean taste, Nice faucet
Cons: Slow pour
No, I would not recommend this to a friend.
