Reviews

Awesome unit

"Great system and easy installation. No issues/leaks. Had older versions put in previous homes a long time ago. APEC definitely made it so much easier and better to install. Plus the best part is getting an alkaline set up all in one. Would highly recommend anyone to purchase this unit. The water flow is excellent on this smaller tank unit."

— Alex M. (5/5)

Excellent Product

"The kit came well packed, the box got banged up a bit in transit but the great packaging protected everything very well. Instructions were very clear. I modified things a bit, as I wanted a switched UV filter in addition to the 90 GPD system with the remineralization. I don't believe that option was available. I installed my kit in the basement, and mounted everything to board on the basement wall below the kitchen fridge, which where the existing fridge waterline hookup comes down to the supply pipe. We get our filtered water exclusively from the fridge, so I didn't install the provided faucet that I received with the kit. I will say that I wanted more flow than I initially experienced after install, so I brought a 1/2" copper pipe and quarter turn stop right to the board where the R/O unit is installed. This has helped a lot, but I'm a nerd, so I'll convert more of the system to 3/8 tubing, one part at a time, until I'm satisfied. If this were installed under the kitchen sink as intended, I'm sure it would have worked just fine. This is a very high quality kit, and the phone support was very good. I highly recommend APEC Water."

Excellent

"Very pleased with the RO filter. Easy to install. Works very well. The entire family is enjoying the clean fresh water."

— Grant P. (5/5)

Perfect filter system.

"It's handy to use. System filters the water perfectly for me. For whatever reason I don't tolerate tap water and have to have my water filtered. Have tried other systems and they didn't filter the water enough for me to use. This system is the only one that works for me."

— Judith A. (5/5)

RO PH90

"The ultimate in soft smooth taste. No chalky after taste. I highly recommend this unit. I will always have one under my sink or wherever convenient. Water is the important thing as we need it almost as much as air but less than food. The Sustenance of life. We are mostly water."

— Bill B. (5/5)
