Good water but filter leaks
on August 27, 2023
Posted by: Giovanni
from Dallas, TX
We enjoyed the clean water but one of the three filters is leaking. I patched it with plumbers tape even though the directions say not to use tape. We've used the filter long enough to change it again; so now its leaking as before. Plumbers tape didn't hold back the leak this time. We got a year out of it. Now I have to replace with a different system.
I would recommend this to a friend!

Absolute trash

Literally every single time we replace the water filters, this doesn't work properly afterwards. The flow rate drops way down to the point it's dysfunctional or starts sputtering and spraying water irregularly until it finds a steady flow rate of like one cup per minute.
Cons: Slow pour
No, I would not recommend this to a friend.

The Aquasana 3-stage under sink filter was easy to install with no leaks. The water tastes great and the new dedicated faucet looks good. The faucet might be a little bit lightweight. We'll see how it survives the bumps common in the kitchen. So far, so good!
Pros: Clean taste, Good Water Flow, Nice faucet, Easy to install
I would recommend this to a friend!

So frustrated.
on July 25, 2025
Posted by: Dan Cape Cod
from Cape Cod MA
I have two of these in both my homes. Do not buy this product! Every time you change the filters it’s a different experience. And they know they have this problem. Right now my system is down to a slow “filtered” trickle. Takes over a minute to fill up my small yeti. So frustrating. I’ll be tossing both and switching to another brand as soon as I do some research.
Pros: Clean taste
Cons: Slow pour
No, I would not recommend this to a friend.

I like the unit and taste but the flow and fill rate is painfully slow. Disappointing!

The fittings are not at all what I'd hoped for in a system That keeps the same pressure as the rest of the house at all times. I sure as heck don't want to try but pretty sure I can pull half of the tubing out of the sockets with less pressure that a newborn could apply.
Pros: I got what I paid for
Cons: Not happy with business practice, Not happy with fittings, Uses Lots of Replacement Filters
No, I would not recommend this to a friend.

I loved the smaller three filter unit and was excited that the max flow would be faster, so I changed out the old one for the new model. But guess what? The flow rate is much slower. The old one filled an eight ounce cup in 10.5 seconds, but the new one takes 19.3 seconds. I will contact customer support for any suggestions.
Pros: Easy to clean, Clean taste, Durable, Easy to install
Cons: Slow pour
No, I would not recommend this to a friend.

Great tasting water
on January 21, 2018
Posted by: Aqua freea
from Pittsburgh, PA
I installed this myself 8 months ago. Nice clean appearance on the counter top with the brushed nickel faucet. Easy installation with the push-in plastic water lines. Flow rate is really nice. 1 cup of water in 7 seconds. Better coffee, cooking and drinking without chlorine.
Pros: Easy to clean, Clean taste, Easy to install
I would recommend this to a friend!
