I installed this filter to replace a filter that I could no longer purchase filter replacements. It installed easily, and I had no leaks or any issues. The problem was that the flow rate was far less than what was specified, it was about 3 times slower, it was rated at 0.5 gal per minute and it actually took 3 minutes to meter out 0.5 gal. I checked my water pressure and it was normal (>80 PSI), I tried a few more things, and contacted the manufacturer. Basically it is what it is. If you have the patience to wait for your coffee pot to fill then go ahead and buy this filter.By the way I do think the quality of the filter and faucet are good. The filters are easy to remove and change. It’s just the darn flow rate that really kills the joy of this filter.

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!

This was very easy and straightforward to install, though a little difficult to tighten down the faucet with just one person. My water has sediment and strong chlorine smell and this filter removes both. The water quality is excellent, where before I would never drink my tap water. I’m kicking myself for not installing this sooner.

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!

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.

Easy to install. Great tasting water, good flow, better faucet than older models, good quality all around.

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.

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.

This system is just another water filter. The faucet is a bust. The nozzle is too straight down, not allowing you to set a container in the sink to fill. You have to hold everything to fill. Also the new filters do not include new O-rings. Eventually they will start leaking. The water flow is terrible. Take forever to fill a glass or container. The plastic tubing concerns me that it will eventually fail or leak.

The faucet keeps coming loose. It needs a bigger nut and.washer. The rate of flow is very low. I have GE system on another sink that never came loose and has a better rate of flow. I purchased the Aquasana because it looked better than the old GE.I am disappointed in the Aquasana.

Excellent water taste but water flow is very slow.

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

Very neat install and easy. Good looking and doesn’t take up too much space.

The unit is built well and directions are very good. Simple to mount under the sink if you are a little handy. I would have given unit 5 stars except the flow rate is fairly slow. I don’t mind waiting a little to have clean water.

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.

I seen some reviews about leaks but in my opinion that would be caused by not installing correct, if you don’t have experience with plumbing hire a reputable plumber to install. Make sure you do not overtighten fittings. Got hooked up with no leaks and filter works great. Pretty good water flow for a 3 stage filter. Took the chlorine taste out and made water taste pretty good.

I have an ice maker line that needed to be attached and Aquasana couldn’t/wouldn’t provide an extra piece of hose and extra fitting. So I had to search until I found the correct pieces and then order them on line. Very frustrating. You’d think Aquasana could have made this common part available. Also, even though this is the “Max Flow” version, it’s pretty slow – and getting slower after one month of use. Water tastes good.

Instillation was easy, the video was very helpful. I had some difficulty pushing the tubes all the way to their marked spots. There was leaking the first time because I hadn’t pushed the tubes in all the way, but I completed the tube insertion and it has worked great since then. My family has water I am comfortable with them drinking! It works great, with a great flow. Peace of mind

I love our new filter. The water taste fresh and clean.

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!!
