Customer Reviews for Aquasana - OptimH2O Reverse Osmosis + Clayrum 3-Stage Under Sink Water Filter System with Dedicated Faucet - Oil-Rubbed Bronze

Tempted to put much lower than 5 stars due to stubborn leaks. I had to replace one of the ‘sump caps’ twice (the first replacement ended up worse than the original). I also replaced the manifold. Fortunately, their customer service saved the day (actually I consider that it was all due to Amber).
The prompts on the review process tell me to keep focused on the product and ‘avoid writing about customer service’. But I cannot separate the two. If my review is only about the product, then look elsewhere! There should not be this type of stubborn problem. I don’t like that I had to throw away two new sump caps even if they were replaced for free because I don’t like the idea of filling up my local landfill. But it was Amber that makes me happy with this product as she helped me troubleshoot where the leak was coming from and then got me sorted with the right parts. And now I have a good water filter system.
I like the filtered water but as someone who worked in the drinking water industry several years ago, I’m one who believes that water filters such as these all have similar abilities to remove unwanted components.

The water tastes great. However, the amount of water wasted by having to run it for a full minute every time you use it is quite ridiculous. The faucet itself is also very cheap. I removed a gorgeous polished nickel high end tap to install the oil rubbed bronze flimsy faucet. It's a terrible finish and terrible quality. Flimsy and ugly!
Pros: Clean taste
Cons: Difficult to install, Not durable
No, I would not recommend this to a friend.

Having hard water with ‘floaters” was concerning. I appreciate the system being relatively easy to install, the quality or the water, as well as the affordability. Not being a multimillionaire, and being able to get a quality system was impressive. My only recommendation would be to watch the installation video as well as reading the guide
Pros: Clean taste, Long lasting filter, Nice faucet
Cons: Slow pour
I would recommend this to a friend!

DO NOT BUY! Canister will leak and cause flooding

Purchased this water filter several years ago and it was working fine. We came home one afternoon and our kitchen was flooded. The hardwood floors had warped and there was water spraying out of the bottom of one of the canisters. From reviews I have read, this is a common problem. I believe a class action law suit should be addressed. I know there are many others out there that have had the same problem. There is no way it is this common and Aquasana doesn't know about it or address it. I would like to add a photo to show the bottom of the cracked canister, since it looks like every other one I have seen in reviews, but the portal won't let me. DO NOT BUY!!!
Cons: Not durable
No, I would not recommend this to a friend.

My unfiltered tap water measures 470 on a Total Dissolved Solids meter. After running the water for more than 10 minutes, I measured the Aquasana filtered water with a Total Dissolved Solids meter and the reading is a disappointing 507! After two weeks of use, the reading has not improved. The water that comes out is also yellowish. Did I get used filter cartridges with my new purchase of the system?
Cons: Cloudy Water

I purchased this Filter 4 years ago with no problems "At First".
1)Come time to replace the Filters, No Stock to be found anywhere in the USA, Had to Wait three months.
3) Customer Support was not much Help
4) the new filters Are two Short to activate the Valve in the Filter Unit
5} After a year of use with the new Filters, two of the Filter Canisters Started bulging at the bottom.
6)Just two day ago the center Canister burst on the Bottom spraying water all under the Sink
At this time I am "DONE" with this Company
Do not Spend your hard earned money with this Company

I have owned and install 4 of the Aquasana under sink water filtration system over the past several years. Each time I purchase one it appears to be a cheaper made than the previous one. I cant stop this one from leaking at the small fitting. I've tried to remove the fitting in order to replace it but no luck. I have to say I will not purchase this brand any more.
