Review: Enjoying clean water - Great system - I always had a whole house carbon block filter in my houses, but this takes clean water to a new level. I run 2 ice makers and the one sink faucet supplied. I added another 5 gallon tank in parallel to the supplied tank so I would not run low on the RO water when filling pots of water for cooking, etc.. Using two tanks actually improves the water pressure at the sink faucet. Was easy to install. I put it in the basement below the sink area so the unit did take up cabinet space.
Review: Not worth it! - This is the 2nd. one that I have had. Seems legit me every 6 months or so the system pressure drops and it trickles and I have had problems with the lines leaking. Call company and they replaced the first one and here we are again and no response! This cost to much to have so many problems and then to be ignored.

## Features

- Alkaline water- makes mineral-rich alkaline water with the VOC Carbon ph+ Mineral Boost water filter right from your kitchen tap water. It uses a proprietary blend of healthy minerals with our activated carbon to not only remove VOC contaminants, but also add healthy minerals and alkalize the water
- Certified NSF/ANSI Standards - Tested & certified by IAPMO to meet NSF/ANSI standards 41, 53, 58, 401, and P473 for water filters, which include 84 contaminants, microplastics, and PFAS “forever chemicals”
- Premium Long-Lasting, Easy-To-Change Filters - AquaTru’s affordable filters are made to last for 360-1200 gallons – that’s a filter change every 6 mos. to 2 yrs. AquaTru Under Sink Reverse Osmosis Water Purifier uses the same water filters as the AquaTru Countertop Purifiers (not including the Carafe)
- Quick change twist & seal filters come included with your first AquaTru water purifier and last from 6 months to 2 years. 1 set of filters replaces 4,500 plastic water bottles, so you can forget about the hassle & cost of buying bottled water
- Patent-pending technology —TruPure RO Sanitizer makes it easy to keep your AquaTru holding tank in pristine condition. Traditional under sink reverse osmosis systems make sanitation difficult to do, leaving the tank a potential breeding ground for bacteria, if not properly maintained

### ⭐⭐⭐⭐ Easy to install had leaks, easy to fix
*by K***X on December 7, 2025*

Easy to install, however like others have said, the connectors are prone to leaking. It didn’t leak at first however it started to after about a day or two of use. Easy fixes, had to tighten a few connections. The worse one being where the line connected to the actual faucet.
