I absolutely love my Aquasana 3-Stage under counter filter! I’ve been buying bottled water for years and was looking for a more sustainable and cost friendly solution. Not only is it reasonably priced, but most importantly the water tastes super clean and delicious. It really makes drinking water more frequently easy!

It’s been great, about time for a new filter I think.

I like the product; however, I would recommend that customers bite the bullet and have it installed professionally. It is trickier than the Aquasana videos suggest and boring a 1″ hole in my quartz countertop was not fun. As for the purification system, it works beautifully.

Love this filter. The water in Texas is not meant for drinking. The water out of this filter is crystal clear. I use it for my coffee maker as well.

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.

It was very easy to install! The water taste great! We now have the peace of mind we are drinking clean water! And we don’t have to buy bottled water anymore!

For now, I will keep it at a 3. The installation should have been easy, however the Spacer was too long for me as well (which has been reported by other customers as well). The water tastes good, seems to remove hard metals and the installation was easy otherwise. They should either provide a small spacer in the package or provide instructions for sawing it if required. Also, the pipes need to be cut square and inserted almost an inch, otherwise it will leak. I would also recommend installing an RO shut off valve, considering there is too many pipe connections.

Installation was fairly easy as I am very handy with tools. This is absolutely the best decision we have made in regards to filtering our water. The water tastes great and we use this water for all of our cooking as well.

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.

My husband & I had to hire a plumber to install it because it was too complicated for us. I had hoped we could do it ourselves to save money. But, we really like the system AND the little faucet actually looks good in the kitchen.

We are very pleased with our Aquasana filter system. It was easy to install and looks great in the kitchen. The water flow is great. Our water taste much better and we feel safer knowing our water is filter through the Aquasana system. We also like the fact that the filter lets us know when it needs changed.

Installation was not too difficult but I recommend reading the directions a couple of times and familiarizing yourself with the parts prior to starting the install. The water quality is great and the only con is the amount of water that is wasted to produce the clean water, 3 cups wasted for every cup you drink. After enquiring about it, I was told this is the most efficient RO system on the market. Apparently some have ratios as high as 20:1. It would be nice to know this prior to buying and installing but there is no mention of it anywhere on the website.

The filter is installed and is working properly, though the they substituted a fitting that was suppose to connect the water line to the faucet but the fitting fit the RO vent line instead of the water line fortunately I was able to use the fitting from the unit I was replacing.
Marlin Tillman (verified owner) –
The installation is straight forward, and have good water flow once connected. Though, I find the two hose provided in the package is a little too short, and I was not able to put the filters to either side of a corner cabinet. Also the filters can get unlock quite easily, which causing water leak if you bump on the filter unexpectedly.

We have had two Whirlpools. They seem to discharge a lot of water. This we never here running. They water taste great. We lived in Texas West the water is terrible.

Much faster than a water pitcher.Easy to install, not so large filters as to not fit under the sink
