This unit was very easy to install and it can be done in under an hour. You need to make sure that you follow directions when it comes to setting the press fit lines into the unit, they need to press all the way into hard stop. My only criticism of this product is that the line supplied in the kit that is intended to go from you cold water in to the in of the water filter unit needs to be at least a foot longer. I don't know how these manufacturers come up with average length needed, but it needs to be longer. Water tastes good so far, I am noticing that the water temp is a bit warmer than the actual sink tap cold water though.
Pros: Clean taste, Good Water Flow, Nice faucet, Easy to install
I would recommend this to a friend!

Water tastes great.Only drawback is we have a well and when pressure tank is on low end water runs very slow. Not a deal breaker we still like the unit.

Devastating System Failures
on July 30, 2025
Posted by: Matt J616
from Chicago IL
I bought the Aquasana 3-Stage Max Flow Under Counter Water Filtration System in March of 2020. It really does change the taste of te water and remove the chlorine which is great. Since the first filter replacement the first cartridge in line would leak if it was screwed in all the way. Water wouldn't flow through it. I would have to back it off an 1/8th of a turn to stop the leak and get water to flow through. Each time i would have to fine tune this, while it drips and leaks in the cabinet, then i have to check it every hour for the first day after replacement to make sure it didn't start leaking again. I ended up setting the whole unit in a tray to catch the drips and protect the cabinet. Finally one of the seams in the top manifold started leaking and spraying water out. It over flowed the drip tray, the cabinet and leak through the floor to the basement, destroying the ceiling and soaking the carpet. I have 2 sets of replacement filters on deck but am really hesitant to buy this again.
Pros: Clean taste, Easy to install
Cons: Slow pour
No, I would not recommend this to a friend.

The installation was easy. I'm glad this version uses a metal adaptor (the "brass tee") because the last Aquasana filter I had (the Claryum Direct Connect) uses a plastic adaptor and the screws got stripped too easily, leading to leaks. The instruction manual should tell you that you need 1 inch clearance on each side of the System Manifold. Now that it's installed, I'm happy to use it! My only question is: when I have to replace all the filters in a few months, do I throw them away? Or are they recyclable?
Pros: Clean taste, Good Water Flow, Nice faucet, Easy to install
Cons: Filters need replacing too often
I would recommend this to a friend!

Nice Fit and Finish, Clean Taste, Still Hard
on September 25, 2025
Posted by: Brock J
The water has a great clean taste to it. Definitely removes the chlorine flavor from the regular tap. Installation was no problem, all parts and pieces necessary for installation were included with the product. Even a novice DIYer could get that right. I added plumbers' tape at all connections just to be sure everything stayed watertight. The only reason I can't give this product 5 stars is because when you test the water for its PPM it still measures out as being very hard. I understand this product is not necessarily designed to eliminate hard water, but with that many things still remaining in it (its literally a few PPM lower than the regular tap) it leaves you wondering what it does filter? This may be my own ignorance of how these things work, or it should be doing a better job. Not sure? Maybe the company can respond here to educate people about what this product really cleans your water from. Because of these unknowns, I can only give this product a 3 of 5.

Thank you for bringing this to our attention. Customer satisfaction is very important to us, and we appreciate the opportunity to clarify. TDS meters measure the total dissolved solids in water—which can include both beneficial minerals and unwanted contaminants. When contaminants are removed through filtration, the levels of certain minerals may increase, which can sometimes result in a TDS reading that is the same or even higher than before. We understand this can be confusing, and we encourage you to visit our Blog https://www.aquasana.com/info.html for more in-depth articles that explain how TDS meters work and what their readings really mean. Please let us know if you have any further questions or concerns.
