Installation was easy, all the fittings needed are supplied. I was able to use my existing fixture so it matched the rest of our fixtures. I like not having a tank under the sink taking up a lot of space. The water tastes much better than our tap water, no taste or smell of chlorine. We are very happy with this items at this point. Installed for 30 days.

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

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.

The installation of this 3-stage water filtering system was easy enough and as explained in the documents. The house has a new Aquasana whole house water and softener system as well and I am happy with it, thus far. But at this time don’t see the benefits of this 3-stage. I don’t like the taste, there is a taste to this water, and the water taste better coming from the bathroom tap which is tied to the Aquasana whole house water and conditioner system than from the kitchen under the sink 3-stage. I’ve tested the the water quality with a TDS tester with the following results: the water coming into the house tested at 547ppm, the filtered whole house water is 213ppm at the tap, but the under the sink 3-stage tested at 381ppm. I admit that previous to the Aquasana installations, we had been drinking bottle water for the last two years which is that is truly tasteless water for sure and we are use to that but this 3-stage has not met my expectation as far has the taste goes.

I absolutely love Aquasana. Great product! Easiest Install. Great tasting water. It was the water pressure flow that sold me on Aquasana. I had an under the sink water filter before, but it was dreadfully SLOW. I just couldn’t take it anymore. The Aquasana pours out like a water socket should, and I’m so happy now. They have great customer service, too!

It works nicely the favor is comparable to a cheap water bottle taste. It takes a bit to fill up an 18oz water bottle. Haven’t had any leaks.

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.

I have used Aquasana’s countertop filter for years but we finally bought our own house so I knew I had to get one for the sink. It was very easy to install. I only needed my husband’s help because my arm wasn’t long enough to reach for one part, otherwise I was able to do it myself. It is so convenient and quiet. I feel safe drinking the water knowing it has passed through Aquasana’s filters.

My husband was able to install it on a weekend afternoon. It definitely does a good job. We have a water distiller so we put filtered water versus non filtered water in it and there was a big difference. The Aquasana filtered water left no residue in the distiller.
