APEC Water Systems RO-Hi Undersink Reverse Osmosis Water Filtration System

I absolutely love my RO-Hi – Ultimate 5-Stage 90 GPD High Output Fast Flow Reverse Osmosis Water System. I use it every single day to hit my 1-liter daily water drinking goals, and it has completely changed my routine. No more hauling or refilling multiple 5-gallon jugs downtown. That alone makes this system worth it. I turn on the faucet, and I am good to go. Simple, clean, reliable. Thank you God. The water quality is outstanding. I test my water frequently, and I consistently get 7–8 ppm, which is excellent. You can literally taste how clean it is. Knowing I am drinking water this pure gives me real peace of mind. I love this system so much that now I am wondering what else I can add to it. Are there any accessories or upgrades available, like an additional alkaline remineralization filter or something similar? I am curious if there is a way to push the ppm even closer to zero, even though it is already amazing. Anywho, I just had to leave this review because I genuinely love this system. Love it. Love it. LOVE IT.

Couldn’t be happier. So pleased and so are my wife and kids

I installed this item but it leaked many places, I tried to fix it by used tape, then glue but failed, at last I have to throw away

before installing the Apex system, I would get a white residual in my coffee pot after each brew. Al gone now!

Unfortunately, our plumber hooked up the RO unit and could not get pressure to have proper water flow. I would love to return the unit and get a replacement. Please advise how to proceed. Thank you so much.

I got the Hi ro 90 with PH with 3/8 output lines. Im running a 3/8 push to connect 3/8 line going to my bar sink and 1 line going to ice maker. without permeate pump , i had low pressure at bar sink (i did not use included faucet. to small for my need, cooking and large coffee pot) Without permeate pump i had low pressure at the bar sink which with low flow , pretty sure my ice maker was not working right either, and it took forever to recover the water tank , with permeate pump my pressure look like it doubled and the flow. and my tanks seems to refill twice as fast. overall good kit. wish there was a quick connect filter version. and its dumb that not all units come with permeate pump. FYI i'm on city water and my pressure regulator is set to 55psi. hope this helps someone out there.

Love the unit but had 3 leaks when I first sent water to it. Hose to the PH and both elbows on either end of the big filters. I was able to fix but added time re doing the connections, wasn't too happy about that but all is great now.

QC issues. Tubing leaks due to short bend radius between calcite and coconut filter cartridges. Stage 1-3 Input and ouput connection leaked, had no teflon tape. Do not install this without bench testing the entire system for leaks.

Fairly easy to install. I added a mineralizer to the system and the water tastes great.

We love our new RO system. Had a plumber install as our connection pipe was too short and had to be adapted. It leaked a little at first but our plumber came back and tweaked it. No leaks now and the water tastes great. So happy to have clean drinking water without the worries of contaminates for the family.

We are not that handy, but installed this ourselves with help from a YouTube video. Everything worked great with no issues and the water tastes great. We got the version with the remineralization filter added.

Overall this is a good system BUT the mounting bracket for the 3 - 10" filter housings is real flimsy and next thing to a piece of junk. If you're looking for a spring board to go swimming this would work great.

Getting this was one of the best decisions in our family. We now have fresh, clean water to drink and cook with. Thank you APEC!

Excellent unit. I upgraded from an RO-90 with 1/4" tubing to this one . . . . 3/8" tubing. I wanted more flow out of faucet and refrigerator. This unit has solved all my flow problems.

Replacement filters not same the ones that come with when you buy the system. . . very poor quality. . change mine twice In o e month. . . they only blame it on sediment from the municipal.

The first time we had put the system in it was almost 10 years ago. It was time to replace it and I even love it more because it seems like the water comes out more quickly with the new faucet. It still does a good job.

Our consumption of pure water skyrocketed as a testament of a great product

We wanted to assure ourselves that e had pure drinking water in our home. I saw a respected doctor online recommended this brand so we got one. I’m truly amazed at the difference in taste!

I phoned your company before buying the unit which was critical to my decision making since the rep asked specific questions about my water source and lab results (I have a well). I installed the “Ultimate RO-HI” system and love it now that it’s in. The installation guide was well done and the one sheet system diagram was very useful. I recommend you include a “T” and shutoff valve for an ice maker connection.

Love the higher output. The wife has stopped complaining about the time it takes to fill her mug!
