Outstanding Water filter!!

The filter has been a life changer! My home's water had a very strange taste and wanted to buy a filter that can be used for clean water in my kitchen. Installing the 3 stage max flow was relatively easy and it complete shocked me how great and smooth the water was after running it from the new faucet. Extremely good and will recommend to all my family and friends!
Pros: No odor, Clean taste, Good Water Flow, Durable, Nice faucet, Easy to install

Enjoying the water.

Here it is.
Install was straight forward. Simple, but installing thing in the cabinet, and under the sink are as to be expected. But overall the process was simple, only complaint is the faucet, I am wary of possibly over tightening, and felt the top ring and washer were both too flimsy and undersized slightly. The fixture is as secure as I want. And I am considering a sturdier alternative. Also surprised the spigot/stem tube is only secured by the o-rings and pulls out it seems, too easily.
Would have been nice to have had both inlet and outlet be 3/8 tubing.
Otherwise happy to have it.
Pros: No odor, Clean taste, Easy to install
Cons: Slow pour

Terrible Product
on February 28, 2024
Posted by: Erin C.
from Florida
It would be a great product if it worked. I bought this just over 2 years ago. I’ve replaced the filters regularly and each time has been a frustrating experience. As others have mentioned, the “sumps” have a vacuum seal and are virtually impossible to open. This time has been the worst, though, and is the final straw. (Which is sad because I’ve been a customer for 10 years, I think.) I followed all of the instructions to replace the filters. It worked beautifully for a few hours and then just stopped working. No water flow at all. I’ve now taken it apart seven times and the exact same thing happens… it works for a few hours and then stops. I’m so beyond frustrated! I can’t keep battling with this thing so it’s time to find another system.
Cons: Difficult to install, Not durable
No, I would not recommend this to a friend.
