Poorly made, NOT user friendly, and frustrating.
on September 7, 2025
Posted by: Nancy L.
from Sacramento, CA
I've had the Three Stage Max Flow under sink unit for almost exactly three years. Every single time we've had to change the filter its a new, frustrating ordeal. Never the same experience twice. It's become a joke in our household when the new filter arrives in the mail, because the dread for the installation saga is so real. I've even had my handyman do it on two occasions until he said he couldn't do it anymore, because he can't in good faith charge me for the actual time it takes him to get through the project. Now with this last change, the leaking from the number three filter won't stop, no matter how many times we remove and replace it. My husband suggested we need a new housing, clearly something inside is broken. The housing unit is cheaply made, entirely of plastic so that's not a bad assumption. I hesitate to spend another penny with this company, but I checked for replacement parts and naturally, there are no replacement options for this piece of the unit. So the entire thing now goes into the landfill, and I will find a more reputable company for my water needs. The only positive thing I can say is, at least I don't have to change those filters anymore.
Cons: Slow pour, Difficult to install, Not durable
No, I would not recommend this to a friend.

Flow Rate!
on July 25, 2017
Posted by: QueenConsort

I bought this system as I was unhappy with my previous non-aquasana unit, mainly because the water came out in a trickle. I was impressed by the contaminant reduction of this system, but blown away by the flow-rate - it is so fast.
We now use filtered water to fill up stock pots for cooking, not just for drinking, because of how fast the water flows. Awesome!
Pros: Clean taste, Durable
I would recommend this to a friend!

This filter was easy to install. However, the filter canisters leak at random, regardless of use. Went away for Thanksgiving to find the bowl I placed underneath it FULL! After 2 weeks of use, I am uninstalling.
Pros: Clean taste, Good Water Flow, Easy to install
No, I would not recommend this to a friend.

Defective Design - Leaks
on February 18, 2025
Posted by: Matt1234zxq
from MI
My kitchen has been flooded twice now because of this 3-stage max flow filter. The design of the unit itself is faulty and WILL fail. The brass coupling that connects to the filter does not last and will fail after about 6 months. This has happened to me multiple times. DO NOT RECOMMEND.
No, I would not recommend this to a friend.

A large amount of white crystalline powder appears
on April 18, 2024
Posted by: EricBai
from California
I bought a Aquasana under sink water filter, Claryum® 3-Stage Max Flow at December last year, Upon installation, I noticed what appeared to be an oily film floating on the water's surface coming from the Claryum® 3-Stage Max Flow. For the next week or two, I used it only to wash things.
After using Claryum® 3-Stage Max Flow as drinking water for a few months, I've discovered that the water that comes out of the Claryum® 3-Stage Max Flow has a lot of tiny particles floating in it; and a thick layer of white crystalline powder on the inside wall of our water boiler. This has never happened before with Claryum® Level 3 Maximum Flow.

Great tasting water
on September 7, 2019
Posted by: SonataSM
from Pittsburgh, PA
We really enjoy our new water filter. The water tastes great and it's wonderful to have the dedicated faucet for our filtered water. It looks so nice. We had a one filter on the counter filter previously. It was unsightly and awkward to use. Knowing now that our drinking water is removing so many more contaminants gives us peace of mind. We are no longer buying bottled water. YAY!
Pros: Easy to clean, No odor, Clean taste, Good Water Flow, Nice faucet
I would recommend this to a friend!

Cons: Slow pour
No, I would not recommend this to a friend.

We're sorry to hear that we did not meet expectations in taste! In consideration TDS, or Total Dissolved Solids, is the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium. Based on the product that you're inquiring about, it is tested and certified to NSF/ANSI Standards to reduce up to 99% of 78 contaminants plus sediment. For an accurate measurement of the performance of our system, you can purchase a water test kit at your local hardware store. If you have any further questions, please contact us directly from Monday - Friday 8am - pm CST.
