Customer Reviews for Aquasana - OptimH2O Reverse Osmosis + Clayrum 3-Stage Under Sink Water Filter System with Dedicated Faucet - Chrome
Posted by: Perfectionist Judy

Verified Purchase:Yes
We are enjoying good tasting water that is the cleanest we can get without taking minerals out. The filters are connected to our refrigerator and a dedicated faucet on the sink. The water pressure is really good - even the fridge pressure is much better than with the filter it used to have.
Pros: Clean taste, Long lasting filter, Good Water Flow, Nice faucet
I would recommend this to a friend!

The filter itself is solid, water tastes fine and I have no reason to believe it's not good. But the fittings arent water tight; I'm constantly drying out under my sink and am on the lookout for new 3rd party fittings I can use to get a proper seal. I'm concerned it will cause serious flood damage before I find a solution.
No, I would not recommend this to a friend.

We have used Aquasana countertop filters for some time, so I am comfortable with the degree of filtration. Also, we are now spoiled by the taste, and don't want to go back to the (overall quite good) tap water. But the outflow was slow, and the attachment mechanism ugly and inconvenient (though we were used to it). The Claryum max flow system looks much nicer, as it connects to a dedicated faucet for drinking water. It also comes out quite fast, which adds to the convenience.
We did not have much room under our sink, but I measured beforehand and it did (barely) fit. The installation instructions were ok, but Aquasana also has videos on youtube to help with installation that made it much more accessible. I'm not the most handy person, but I was able to install it without any issues.
These filters are basically made of cheap plastic, so the quality isn't amazing (we've had two countertop units break). But it works well and isn't overly expensive, so we are comfortable with Aquasana products.
Pros: Clean taste, Good Water Flow, Nice faucet, Easy to install
Cons: Not durable
I would recommend this to a friend!

This is the best absolutely best water I have ever drank. I’ve been drinking bottled water for years and it doesn’t even compare. It’s so pure and clean. I just don’t have any words to express how happy I am

Canisters cannot support water pressure
on February 1, 2018
Posted by: garyhelminski
I've had leakage problems with this unit,
Two of the water casters deformed, broke and caused flooded my kitchen. Wood floors warped and needed replacement. I've also has leaks at the top of the manifold. It's an expensive product for the rather cheap plastic construction of the unit.
No, I would not recommend this to a friend.

Maximum life time is 18 months to 24 months

I bought this system 2 years back. I noticed cracks on the inside walls during first time replacement. Those cracks slowly started appearing outside and the bottom portion of canister on black and red colored ones bulged from flat surface to round and started leaking. These canisters cannot hold water pressure for more than 12 months of continuous usage. I admit that water tasted great.
Pros: Clean taste, Easy to install
Cons: Slow pour, Not durable
No, I would not recommend this to a friend.

Great when it does not leak!
on March 8, 2021
Posted by: Upset in RI
from Bristol, RI
Our filter was recommended by our contractor and professionally installed by a plumber. I researched the product and read the reviews before purchasing the filter. I noted that the most common complaint related to the unit leaking after replacing the filters. For the first six months (prior to filter replacement), it was great. Water tasted great and we were very happy. Then came the replacement filters. They were easy to replace, but immediately began to leak as soon as the water came back on. I tried removing them, cleaning the o-rings (not by removing them, but by wiping them), tweaking them a bit, etc. All top no avail. I called customer service and they gave me advise about switching the heads (so the colors would not match the filters), which I refused to do since the whole system is color coded and that could lead to confusion. Besides - that is a bogus way to fix a problem where the clear issue are the o-rings. I pointed out that the design was defective and that logic would dictate that with each filter replacement, the company should supply o-rings. I'd pay for the o-rings, as it makes sense those would have to be replaced. The representative actually agreed with me, but said that was not how they were designed. The only way to fix it was to get new heads, but that I would be charged for shipping. Apparently that is part of the contract for getting filters automatically. It is all clear now - the company makes a defective product and then makes it part of the contract that you have to pay shipping for the new heads with each filter replacement if they old ones leak. In my worldview, you stand behind your product and you support the customer when the product fails, especially when it is a design defect! It is truly unfortunate because, when the system was first installed and was not leaking, it was truly great.
Pros: Clean taste
Cons: Not durable
No, I would not recommend this to a friend.

Poor quality. Flooded kitchen and basement
on July 27, 2024
Posted by: Beware flooding
The mechanism used to attach the filter to the water pipe is very poor quality and not suitable for this type of water pressure. We had our filter installed with the help of a plumber friend and 3 days later the hose came off and completely flooded our kitchen and basement. I lost count after removing 50 gallons of water in the basement.
Cons: Not durable
No, I would not recommend this to a friend.
