Questions & Answers


What is the total vertical space required for installation, with room to change the filters?

Asked by Annx April 11, 2021

I don't own the home anymore, but it was under the kitchen sink. It was a little tight when we changed the filters. My water was questionable at this house and this system worked very well.

How long is the poly tubing that's included with the faucet system?

Asked by JTP2 March 18, 2021

There are two. They are roughly 2 and 3 feet.

Do you have to use the provided faucet? 

Asked by KimVH March 3, 2021

No, but the faucet you use has to match the connector to the filter. FYI: We have recommended the filter to several friends and family members and all have chosen to use the faucet that comes with the filter.

How can I install this system for water dispenser on countertop and to the ice maker line to refrigerator?

Asked by Deb In Florida February 12, 2021

You can go to your local hardware store and get another fitting just like the one Aquasana sent you with your install kit. Install that fitting right on top of the fitting you installed from Aquasana then hook up the service line to your counter top dispenser. Now you have a place for the water line that feeds your filters and the water line that feeds your refrigerator. I hope I made this clear. Glad to help.

How can I get filter replacement for AQ-RO3

Asked by Duds February 2, 2021

You should be able to order them from the website or have them put on Auto-Ship.

I have the Aquasana app, but the percentage of the filter life isn't showing. My Bluetooth is on. Any suggestions? I changed the battery around, thinking the installer had it in wrong. Which way does the battery go?

Asked by Sonata January 23, 2021

Good luck with the bluetooth. I never got it to work. Now as for the filter, I love it and am on the automatic replacement program.

I recently just replaced my filters for the first time in my 3 stage filter system. Very easy to do but now my water pressure from my faucet is very weak. Any ideas? Thanks.

Asked by Billy6698 January 19, 2021

There is a flow restriction valve in each of the canister heads. Why? Because you can unscrew the canister w/o a leak.  You need at least 40 psi of pressure for the water to pass. Sometimes the valves fail. I had to punch out my first filters valve to get it to flow. Now it flows great. But the canister will shoot out water if disconnected. I have to make sure the water is off and the pressure relieved before removing canisters now.  I recommend putting in a particulate filter before the Aquasana filters so the valves don’t get plugged/damaged.

I purchased my unit at Home Depot. Can I still signup for your filter purchase program ?

Asked by Ceros Roman nose January 12, 2021

Anyone can sign up for the filter program.

What micron are the filters

Asked by Donna D January 7, 2021

Hello, Thank you for reaching out to us. The 3-Stage system includes a 20-micron pre-filter before the two Aquasana Claryum® filters. This pre-filter increases the capacity of the system from 500 gallons to 600 gallons. In addition, it improves the flow rate in high sediment areas. If you have any further questions feel free to contact us at 866-662-6885. Thank you, Aquasana Customer Support

Can the faucet head turn from side to side or complete 360 to move it out of the way when doing dishes and things?

Asked by Meredith January 5, 2021

We move ours gently side to side. We are unable to turn it 360 so I don’t know if you can. My mother had one and when she moves it quickly back and forth it tends to loosen.

Keeps Leaking!!!
My filter was installed by a professional plumber amost six months ago, but never stopped leaking. It leaks from filters and from the water connector. I always keep a towel under it. Very sad despite the fact that water tastes good and pressure from the faucet is fine too. Those who use it, you should consider shutting off your water to avoid any damage when you are out. If I had another option, I would have gone with filter pitch such as Brita instead of relying on this faulty product. I am also upset my brand new kitchen cabinet is getting damaged.

Wanted to love it
First of all this unit will be removed and returned when my plumber comes by. Installation wasn’t easy, needed pliers to install the 1/4 inch outlet hose. Of course one on the cartridges started leaking. Water flavor is good. We wanted to love this unit, but it has to may issues.

Amazing Product!!!
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!
by JeanB
I purchased the standard 3-Stage Filter System
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.

I was dying to get this installed because my town...
I was dying to get this installed because my town water is highly chlorinated. After studying the instructions and watching the install video (highly recommend!), it took me one hour to install. It takes two people at some points (someone to hold the faucet while another tightens the nut underneath). No leaks, functions perfectly and the water tastes GREAT!!!! Don’t know how I lived without it all these years. Highly recommend.

Do not like it
i hate it. It’s very noisy !!! It takes five minutes to empty tank and three hours to refill. Too slow of a process! Very very noisy!
by Lynnie
Great Product and easy to install
This product is awsome and very easy to install. The water is very clean, refreshing and tastes great. Filters lasted more than 8 months. The Andriod app helps a filter life remaining. Great product
