Long-Lasting Filters

Step 1 & 2: Pre/Carbon Filter

A mechanical Pre-Filter captures larger particles like sediment and rust, while a Carbon Filter removes chlorine and chloramines for cleaner, better-tasting water.

Lasts 6 months for consistent, high-quality filtration.

Stage 3: Reverse Osmosis Purification

Filters harmful inorganic chemicals, including fluoride, microplastics, lead, chromium-6, arsenic, nitrates, & heavy metals.

Lasts 2 years for continuous, advanced purification.

Stage 4: VOC Carbon Filtration

A coconut shell carbon block filter that reduces “Forever Chemicals” (PFOA + PFOS), microplastics, prescription drug residue, and volatile organic compounds—leaving you with pure, great-tasting water.

Lasts 1 year for superior contaminant reduction.

The AquaTru Under Sink Water Purifier is certified to NSF standards to remove 84 harmful contaminants (the same contaminants as our countertop water purifiers, including Arsenic, Lead, Chlorine, Fluoride, and many more). View our transparent test results here.

Unlike our countertop purifiers, AquaTru Under Sink requires installation. We recommend hiring a certified plumber to install your reverse osmosis system. Installation requires drilling into your pipes under the sink, which is not recommended for individuals unfamiliar with plumbing. Please read through the owner’s manual carefully before attempting to install the system. Proper installation is the responsibility of the installer. If you have any questions or need assistance, please contact our technical support team, who can guide you through the installation process.

Our AquaTru Under Sink purifier uses the same filter materials as our countertop units, and has the following filter lives:

Pre-Filter (yellow): 6 months or 600 gallons, whichever comes first
RO Filter (blue): 2 years or 1200 gallons, whichever comes first
VOC Filter (green): 1 year or 600 gallons, whichever comes first

Normally, under sink reverse osmosis holding tanks can be a breeding ground for bacteria, if not properly maintained. Most people don’t realize they need to sanitize their tank, and usually, the process involves tubing and a plastic syringe. No, thanks.   That’s why we developed our patent-pending, TruPureTM RO Sanitizer that makes it easy to keep your AquaTru holding tank in pristine condition. Simply unscrew the TruPureTM RO Sanitizer, pour in the sanitizing solution, and complete the sanitizing steps only once per year when you change your VOC filter. Just another way AquaTru ensures that you have pure, great-tasting water.

Reviews

After considering several different water

"After considering several different water purifiers, I decided to go with Acqa True undercounter unit. Installation was not hard and it took couple of hours for a plumber to install & test the system. So far I am very happy with the results. I can see & teaste the difference in the drinking water. Big milestone will be when time comes to change R O filter in six months."

I have only had my

"I have only had my new filter about a week but so far I am pleased. My daughter has an AquaTru under the sink filter and she has only good things to say about it so that is why I bought AquaTru. I also got the alkaline filter to add back the minerals that are lost with reverse osmosis filters. It arrived very quickly, in perfect condition. I’ve also read that reverse osmosis is the very best water filter system so I feel I made a good choice."

I am generally happy with

"I am generally happy with it. The installation instructions should spell out the orientation of the washers for the cold water valve. I kept having a leak until I reversed the washer. The water is a little cloudy at first which I assume is very small air bubbles. It clears up quickly."

— Randall A. (5/5)

Love it! We could hear

"Love it! We could hear the tank filling quite loudly. This was solved by relocating the drain saddle and its perfect! The water tastes great!"

— SHELLEY M. (5/5)

Love the water quality. The

"Love the water quality. The drain connection is a weak point in the system. If it gets knocked, it can shift easily. My wood floor in front of the sink is destroyed. The installation instructions that came in the box were not thorough and images were in black and white instead of color. Company should improve for ease of installation. Instead we had to watch you tube videos on repeat and refer to an online manual."

I can’t write a review

"I can’t write a review on this item though your products are highly recommended. We decided we didn’t want to cut our quartz countertops so I returned it."

wastes a lot of water

"I didn't realize how much water this thing would waste. It's also leaking despite following the installation instructions. Not really happy with it and now I wish I would have gotten the countertop version."

— Jimena S. (3/5)

First time buying! It

"First time buying! It took hours to set up. Was leaking after had to figure that out. I think were going to really like it. The only con is the water isnt as cold as id like but its clean. Very affordable the filters are affordable too! Great investiment! We were buying 10 5 gallon waters from homedepot every month! Glad i dont have to buy them now!"

— Samantha (5/5)

House warming Gift

"I have the same system which I installed a year ago. It is very nice to have good water. I purchased this for a friend that just bought a new home. We did add a pump on our unit also. It is very well made unit with no problems since put in April 2025."
