Aquasana provides excellent tasting water. It is so good to turn on the faucet and use clean fresh water for all our cooking and for drinking. It wins in a taste test with Britta and Bottled water. We are so happy to have it! Hurray!

Love it! Peace of mind that I’m drinking clean water. Easy to just turn on faucet and fill my bottle at any time.

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.

We love the 3 stage water filter. Everyone is amazed by the great tasting water.

This filter is great. We live in a small water district. They generally keep the water clean and free from contaminants, however there is still a mineral aftertase. This filter removed it all and the water actually tastes good now. My Wife is a picky drinker, so when she says iut tastes good, it does. Installation was straight forward and the instructions are well written and easy to understand. I had no installation issues at all.

This is the second water filter I’ve installed (used another brand previously), so my impressions are sort of based on that previous experience. Installation was fairly easy, the instructions were very thorough. Took me about an hour for the whole installation, and that included removing the old water filter.As far as the hardware is concerned, I wish the base plate for the faucet that is used to cover up the hole in the sink was just slightly wider, and that a hand-tightened fastener could be designed for securing the faucet underneath instead of a regular hex nut, to make it easier to tighten in tight spaces.The flow rate was a little slower than I expected, since this particular filter is advertised as “max flow.” When I first turned on the water after installation, the flow rate seemed quite fast, but fell off after the filters were flushed. Based on my experience with the installation, I expect changing the filters will be relatively easy, but we’ll see. Until then, I can’t give any feedback on how long the filters will last.

Installation was no problem for the plumber. When refilling the water the unit makes a loud, annoying hissing noise from air escaping the unit while it is refilling.

The quality of the water is comparable to a water de-hardener system, flavor is incredibly good unlike other systems that give you clean water but with a lousy taste! “NOTE, THERE ISN’T ANY PHOTOGRAPHS OR VIDEO BECAUSE I PAYED FOR THIS ITEM!!

We are enjoying our filtered water very much and use filtered water every day. My husband was able to install the system on a Sunday afternoon. We are definitely glad we got this system. So glad to not have to buy bottled water anymore.

So far, I’m not impressed with the quality of the Aquasana 3-stage Under Counter Water Filter. I’ve had a GE two stage system that I thought provided better tasting ( no taste ) water. The Aquasana system removes color from tap water but total dissolved solids are still high (320 ppm) and still some taste.

We had one at our other house so once we moved we bought the RO system gor this house.

All materials needed for installation in the box. Supply your own drill for the counter hole, and in it goes. Took water with a heavy chlorine oder and took it out, no taste or order

Having to wait for water when tank empties is a pain, especially when making my morning coffee. Any remedies?

We used to own a counter top filter many years ago and are happy to be back with an under sink unit this time. The filter was not too difficult to install (even though it was pretty tight under our sink) and we are enjoying the peace of mind now.

I love my new aquasana under counter water system. I was buying bottled water and I know that’s not good for you. My water now tastes better than FIJI water. I call it my fresh squeezed water. Great investment

So far, the filter has been operating fairly well. I got the max flow version and it does have a good flow but the head and sump system need to be evaluated. The first sump heads I received leaked a little bit at first and customer support was fast to replace them. The new heads also leaked but with some adjustments, I got them to stop. It was a few drops here and there. Nothing crazy. The design looks good but here are my suggestions if the company cares to read them:1. Improve the way the sumps sit in the head unit. It doesn’t seat securely and the use of the grommets seem like you could get a more secure fitting.2. Don’t be afraid to use copper. Copper expansion rings/joints are way more secure in the lines than metal ones would be. Or upgrade it so the water in and water out use standard water lines. I’d gladly pay the difference if it meant less leak chance. 3. quality check improvement needed desperately on the sump heads. Two grommets/o-rings were warped before i even inserted the sump and that caused some of the initial leak. Or send some extra o-rings. They cost pennies but would probably help with the leak issue. It won’t fix it because the interlock between the head unit and the sumps need to be addressed primarily. Fix these issues and youll probably get much better reviews and happier customers. 4. Find a way to get air out of the filters. Sometimes air from the water line gets in and slows the flow but when I burp the sumps, water flow is restored.

I have been an Aquasana customer for a number of years now. I recently decided to upgrade my under counter system from a simple two stage to a Max Flow 3 stage. The increase in flow was quite noticeable! After installation I noticed a slight leak coming from the connection between the cartridge and the receiver unit on two of the cartridges. I contacted customer service who advised me to shut off the waterflow immediately. She then stated she was sending out two new replacement parts for the filters. Upon receiving them I replaced the new filters into the receiver and the problem was solved!! The customer service was knowledgeable and excellent!! I look forward to many more years using the automated filter replacement program. It’s the best reminder that it’s time to replace the filters!!! 🙂
