Reviews

Superb Water System

"We purchased this system about 7 years ago. I bought a second 14-gallon water tank. Needless to say, we never run out of RO water. It has been so nice. We change the pre- ffilters every 6 months. The RO filters are replaced every 2 years, or as close as we can get. The water is excellent, and we love it every day. If you are looking for a great RO system, I would highly recommend this one."

RO -90

"I do not live in the UK. I have a RO in the UK and I bought this RO for a property in the US, not for the first time. I have to say that this APEC RO is so good compared to my previous experience in all respects, I highly recomend this system. The instructions are clear and the product is first class. One downside is instructions for connecting to the water system."

Great filter System

"Excellent system, easy to install and doesn’t drop water pressure. . works great no after taste"

— Gregory F. (5/5)

Good unit, good customer service, troublesome install

"Once working, this unit has been chugging away and meets all our needs. My own testing proves it resolved my Ar and NaCl well problems. I enjoy the simplicity, affordable cost of ownership, and the good pressure of the design. However, the first days were rough. Every screw fitting on this unit slowly leaked and I had to re-teflon and re-install every single screw fitting. This was more an emotional problem than a labor one; constantly checking if the leaks returned. Customer service saved the day and my confidence in the unit as we worked through this."

— Christopher M. (4/5)

Clean water from faucet

"There were 2 delays in that the plumber realized our state, WI, requires an air-gap faucet, unlike the one that comes in the kit. So he had to leave and I had to order the separate faucet and reschedule the plumber. Then after install and waiting for the tank to fill, no water came out. The plumber came back. A brass piece in the faucet under the lever had turned 90 degrees blocking the water. He fixed that. So it took some extra time but I am now enjoying the clean taste of my water and will no longer have to lug 3 gal jugs of filtered RO water from grocery stores."
