I had been paying for a popular water delivery service. I became totally frustrated with their incompetence, which included missed deliveries. I then remembered about the under the sink filter alternative. I checked for reviews. Aquasana came up with a very good rating. After receiving and installing the under sink three filter system, I have to agree. This Aquasana filter system is everything that I had hoped it would be. The product appears to be very well made. The instructions were very clear, and I was able to install it with no problems at all. The water tastes great. I only wish I had made the switch sooner.

Due to health concerns, we have been distilling our water for the past couple of years. That process strips the water of all of its mineral content and leaves it tasting very flat. Between the space the distiller required on the countertop, the perpetual cleaning required in order to ensure its performance and the noise it produced when in operation, there was plenty of room for improvement. The OptimH2O has provided us with great tasting water in a super convenient package. No complaints here; just plenty of praise.

Smoothly, my husband installed our water filter in the sink hole where the soap dispenser was located. Brushed nickel matched our faucet. The flow is a little slow but I don’t care since the taste of the water is supreme, even with the whole house water system we have. We do not have reverse osmosis filtering, that uses too much water. Good buy!

So nice to have drinking water again. Our water was terrible had to buy bottled water. We had so much calcium in our water we couldn’t use the ice or drink the water. After installing the filters its like night and day, great drinking water and crystal clear ice. No more bottled water

Had my unit installed by a plumber. Water flow continuously trickled down to nothing. I called the product help line for a fix. I was instructed to remove the first cartridge, remove the filter and put a quarter in the cylinder and replace the the filter. It restored the water flow but what about water quality?

I have not used it yet… It seemed more complicated than I anticipated so my husband and I just set it to the side for a few weeks then finally decided to pay someone to install it and it took him 3-4 hours to install and he had to go to the hardware store for an additional piece that was not with it. Now we’re in the let the tank fill up then let your water run for 24 hours portion of it so I have not tasted the water yet.

Installation was straightforward. The equipment was installed per instructions without modification despite the equipment location being very cramped and difficult to access. Output water flow exceeds specified minimum and water is clear and odorless.

Would have given 5 stars, undercounted nut is too small for installation, had to find thicker nut to install tightly.

In early November, I purchased the 3-Stage Water Filter system. It took me approximately 1-½ hours from start to finish. Upon completion, I removed the plastic insert to start the system and turned on the water supply. Amazingly, there were no water leaks. I flushed the system for 10 minutes, as required, and afterwards, had my first glass of filtered water. The water was delicious! I couldn’t have been more satisfied. I unequivocally recommend the Aquasana filter system I have purchased, to anyone wanting wanting an easy-to-install, inexpensive, under-counter system.

I purchased a aquasana three stage water filter about six years ago. I also got new filters every six months. The system worked flawlessly for five and a half years , then it started to leak just a little. After a call to your service department , your people sent me some new heads for the filters. After installing the new heads, the system continued to drip. I suppose if you can get five and a half years out of your product you’ve done pretty good. With this in mind I purchased another three stage system. I am very happy with the purity of the water, just wish it would last longer.

Simple to install. Everything that was required to install came in the box with straight forward instructions. Quality of water is great. Clean crisp taste!

We love this filter. It’s everything it was advertised to be small, compact, and very easy to install. Also the faucet that delivers the filtered water is high quality and stylish.

I love this filter. My husband was installing it and got a phone call so I took over with my 10 year old. We got it done in about an hour including drilling the hole in the top of the sink. We read the instructions and also watched the video. I thought it was pretty easy. We monitored for leaks for a few days. The water is excellent. We could actually SMELL a difference with our blind taste test. The aquasauna water tastes like nothing. I am very pleased with this system. The brushed nickel matched our existing sink well. I use the water for drinking, cooking, coffee etc.

After moving we bought another under sink. This time high flow. Well worth it. Plumbed for both the sink spigot and the fridge (ice tastes great!) We’ve had Aquasana for over five years now and it is strong value for our family.
