Fairly east to install. Great-tasting water. I highly recommend Aquasana.

Beyond thrilled with this system. The first time you clean the filters you’ll see HOW MUCH DIRT they catch that’s visible. Then you wonder about the invisible stuff. Every time I see a Brita in someone’s fridge, I do a soliloquy about Aquasana. Get this, you will love it.

Resolved the leaking problem after calling the customer service. It works OK.

The biggest problem I’ve had with filters in the past is the water flow; it always is so slow. This unit is much faster. It’s also very simple to install and use; the alarm feature to remind you about filter change time is most convenient and you don’t have to guess anymore. Very pleased and would highly recommend.

The water filter was installed for about 2 months now. Water taste great. The issue that I see and compared to another model that I had before is the water pressure/flow is low, so it takes longer to fill a pitcher of water. However, this is a 3 stage filter, so this could be filtering more than the old unit that I had.

It was put in by my brother in law and I with the help of a neighbor on the finished product. The product instructions were clear and understandable. Once we got it all out and placed in proper order things went well. The water taste was approved by my wife and that was all that was needed to be done. Our water is with the city and it is rated poor, but now the water taste clean and vibrant. Thank you so much for this wonderful product. I am signed up on the filter for life program so I can always enjoy this wonderful life giving device

The installation process was simple! The water tastes great! The spout makes is convenient to use! Really glad to got it! We have not experienced the “refill process” yet. I am hoping that goes as smoothly.

Installation was reasonably easy but the water tastes like tap water. Your agent said that it does not remove minerals that are good because when I tested water the numbers were high. I only use the water for cooking because I do not like the taste. I will probably replace in the future.

I did not buy my Aquasana 3-Stage Under Counter Water Filter new. I bought it from a friend who used it in her coffee shop to filter the water for her machines. She wanted a larger one so I bought this one. Before installing it I replaced the filters. If you do not believe a water filter is worth it you will once you replace the filters and see what it removes. I was very impressed with how easy this was to install and equally as impressed with how much better the water tastes. I’m a customer for life now. I’m so impressed with this product that I plan on installing a whole house unit next year.

We are very happy with the Aquasana 3-stage under counter system. Is is very similar to the system we replaced (we could no longer find replacement filters). The installation instructions were very easy to understand and was installed quickly. Our unfiltered water is very hard and has strong chemical taste. the unit produced wonderfully clear water with no odor or taste–the way good water tastes from a great, fast-running alpine stream!

I enjoy the clean taste and smell. My handyman installed the unit in a matter of 30 minutes and the faucet is very heavy duty and attractive. I had one of these installed where I work and after tasting the difference it made, ordered one for my house also. We both have whole house systems from Aquasana also.

I was replacing older model 2 stage Aquasana filter so faucet whole was already cut in sink. Older faucet hole was larger than what was required for the new faucet. I had to come up with some washers to make it work but otherwise, the install was a breeze. The only thing I could think of that would have been better would have been for Aquasana to provide some sort of adapter kit. Product works well. Water tastes great!

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.

Water taste good. Instalation was easy with all required hardware. Faucet itself is a bit on the cheap side and feels like it could break anytime.Be very careful not to catch the very skinny spout with a dish or pot…The metal sink cover that goes between the faucet base and sink is thin, sharp, cheap and barely….i mean just barely covers the hole it goes through in the sink. Alignment was a nightmare.It definitely does not cover any old scratches…Water taste great filtered through the Chinese made filters.
