Known problem with leaking caps!
on June 20, 2022
Posted by: Jayek
I loved the system until we had to replace the filters and learned about the o ring issue that causes leaks. Instead of fixing the problem or sending a new cap with filter replacement orders, I have to purchase a new cap plus pay for shipping. I liked the water but I would never recommend this system based on that problem.
Pros: Clean taste, Long lasting filter
Cons: Not durable
No, I would not recommend this to a friend.

Sweet & Stylish Clean Water

Other than the typical working around the existing plumbing, the actual filter installation was a breeze. All components supplied fit smoothly and leak free. You can always tell your water quality by its taste. Ours has no taste and that's the best.
Pros: No odor, Clean taste, Nice faucet, Easy to install
Cons: Slow pour
I would recommend this to a friend!

Love my new Aquasana

For years I've gotten 5 gallon jugs for my water cooler for drinking water. When my cooler died recently, I decided to see if an under sink filter would be easier. I installed it myself, was really easy (I already had a hole in my granite, previous owners had an old filter system that I removed).
Much easier! Water tastes great!
Here are the only things I would point out. I was used to cold water for drinking out of my cooler, and the water out of this is not as cold (I'm not an ice person). I work around by keeping a glass carafe of the filtered water in my fridge which solves the problem. I got the Max Flow, and it's not the speediest flow, not sure what any flow less than the "Max" would be like. Finally, the brushed nickel is slightly shinier than my brushed nickel faucet...even went back to see if perhaps I had ordered the wrong one. I've gotten used to it.
I don't miss the cost of the 5 gallon jugs, and I really don't miss lugging them around. This is a big win for me.
Pros: No odor, Clean taste, Good Water Flow, Nice faucet, Easy to install
I would recommend this to a friend!

Good product

We have only used it for a few weeks, but so far the filter works great! It was easy to install. My only complaint so far is that it flows a touch slower than I would like, but it is really not that bad. I think the flow rate is better than waiting for a traditional pitcher-filter to finish filtering before pouring.
Pros: Clean taste, Easy to install
Cons: Slow pour

Overall good.

Used one of these at our previous home for maybe 5 or more years and believe it works well. Appreciate not having real cold water, as from the fridge. Installation isn't bad. Helps if you've worked under a sink before. Instructions are good. I'm not a professional plumber, but experienced DIY.
Pros: No odor, Clean taste, Long lasting filter, Good Water Flow, Nice faucet

We are long time Aquasana users. We recently upgraded to the Claryum 3 stage system and we are very happy. The flow is excellent and the water is clean and tastes great. It was extremely easy to install and filter change, while it hasn't been needed yet, seems easy.
Pros: Clean taste, Good Water Flow, Nice faucet, Easy to install

Not worth the flooding
on July 27, 2023
Posted by: Lauren C
from Baltimore, MD
I want to like this so much, and when it isn't causing a flood in my house, it is great to have such quick and easy access to great water. The connection to the supply line is a very delicate and precarious connection and I spent Christmas Eve draining a foot of water from my basement and kitchen that rained down from the supply line slipping out. It was such a nightmare. When the plumber connected it she had to give such specific guidance to her apprentice about how carefully to not under- or over-tighten the connection that I was skeptical that this is really something that should be billed as self-install. This has been an ongoing problem as it will leak or slip out if you so much as breathe near it. I would recommend not having anything stored under your sink anywhere near the supply line. If you have to do any plumbing, like replacing your kitchen faucet, there is no way this won't slip out. I love having this filtered water in theory but I hate this system so much.
Pros: Clean taste
Cons: Difficult to install
No, I would not recommend this to a friend.

My husband installed this very quickly, it doesn’t take up a lot of room under the sink at all. The water tastes great and I like knowing my kids are drinking water that from a filter that removes so many things including PFOAs
Pros: No odor, Clean taste, Good Water Flow, Durable, Nice faucet, Easy to install
