I'm disappointed the item. I just installed it in late Sept and found that there was so much scale after water boil! I had to use my previous water filter pot after.

A great unit to replace my old one

I needed to replace my outdated 2-stage GE filter which served under our kitchen sink for decades. Found this Aquasana Max Flow 3-stage to be a very nice replacement. It quite nearly fit the exact measurements of the outgoing one. Would recommend this particular model over the shorter cannister ones because of its faster flow capability.
Pros: Clean taste, Easy to install
I would recommend this to a friend!

This filter checks all the boxes. It is well made, installation by a professional was fast and easy. Water tastes great. I chose the filter because of it's broad coverage of contaminants. I combined it with an epic nano pitcher that takes care of micro-plastics in addition to what the under sink filter provides.
Pros: Clean taste, Good Water Flow, Easy to install
I would recommend this to a friend!

Unit failed and flooded my kitchen and basement
on January 16, 2018

Unit worked for two weeks and then the tube connecting the unit to brass t broke in the middle of the night. Pretty much it flooded my kitchen and basement. Spend a day dumping the water out. I got a plumber to install the unit and he did it by the instruction book. Not sure how the tube came off the the brass T connector.
Cons: Slow pour, Not durable
No, I would not recommend this to a friend.

Had to find other fitting to make connection . There is no change in the water taste . We have hard water here and the water still taste like slime not crisp and clear like I was expecting . Thinking of asking about return . Just don’t feel like going through the trouble of taking it out and shipping .
Cons: Cloudy Water
No, I would not recommend this to a friend.

I am totally frustrated

Verified Purchase:Yes
I bought this under sink filtering system with the hopes of replacing the sink faucet and pitcher products previously used.
So far, it worked for a brief period of time then slowed down to a trickle. Got instructions with two things to try. Tried backing off filters 1/4" and it worked for a brief period of time then slowed down to a trickle and stopped. Tried inserting a coin under each filter. It worked for a day and then the same slow down, stop, intermittent slow flow.
I have spent literally hours on this filter only to arrive at the same disappointing conclusion. I could not recommend this product at this point and am runnoing out of patience. I have had reverse osmosis units in the past and a variety of other brands but none have had this problem. It certainly is not the installation and I am at a loss to know what to try next.
Cons: Slow pour

Affordable water filtration

This is the fourth Aquasana filter I have purchased and installed. I put one in every house I own, and recommend it to all my friends and family. It is easy to install, takes up very little space, and provides peace of mind regarding water purity for drinking and cooking. The faucet is attractive, too.
Pros: Easy to clean, Clean taste, Long lasting filter, Good Water Flow, Durable, Nice faucet, Easy to install
I would recommend this to a friend!
