Great system!

I bought this system for my daughter and her family. I just visited and got to see it and drink the water. It is a perfect system in every way.

Highly recommend this system - fast dispensing

The water from this system tastes great. Compared to other systems I have used this system dispenses water much faster.

Better than most

Great water flow pressure and volume, TDS not mearured yet so 5 stars may be offing should the TDS be lower than my previous R/O.

Best RO system

I bought this RO-Hi water system last March 2022. System was very easy to install myself. Best tasting water since I switch to this system! This system is hooked up to refrigerator as well. Kids tell me the water taste better! Just changed the stage 1-3 filters and very easy to do. Took less than 30 minutes!

APEC RO-Hi-90

My finished basement ceiling is drywalled so I bought two systems; one for under the kitchen sink and one for our new refrigerator. Both systems work great. Plenty of flow and great taste.

Amazing product, delicious water!

This installation was easy. Took my time and read the detailed instructions. I had one leak in the stage one filter housing. This was due to the gasket not seated properly.

Easy to install and awesome drinking water

My wife and I installed this system in a few hours. We have a well and bought the electric pump as well. The water pressure out of the RO faucet is outstanding and we’re getting TDS of 5. Very happy with the purchase, ease of installation and quality of water. Highly recommend!

the flow is much faster than my old system (not APEC brand). very impressed the system is larger than my old system so my space under sink is much more limited than before. But I'm fine with this.

Easy peasy

Got this as a replacement for an old unit that had become a coble job of random mis-matched parts o er the years, and finaly stoped working. This RO-HI from APEC was plug-and-play, and just plane works. I have zero regrets on my purchase.

Awesome system

Easy to install, works great, highly recommended - water tastes great.

Great info and guidance

The directions and guidance provided for installation is spectacular! I over research most purchases including this one. I was impressed w the product description and correspondence w the company. The install is easy and quick. I can’t say enough how nice it is when a company knows how to provide clear directions. I installed the RO-Hi system 3 days ago and it has worked well so far. Water tastes like water and has no bad taste, smell or color. From our limited 3 days of experience, I would buy ...

This is my third system

This is one of the best RO systems on the market. They have great support and stand behind their products. The upgraded fast flow fixture looks great on my granite counter.
