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

We are loving not having to haul heavy jugs of water. The water tastes great and is very convenient.

Works great! A pleasure to have RO water so accessible.

It is awesome, we had elevated uranium levels in our well water and we just had it retested after install and it came back with ND (none detected). Highly recommend

I bought the regular non alkaline back in 2010 and then the alkaline system in 2018… have never had an issue and replace filters annually/bi annually when needed. Keep up the great quality!!

The flow rate is amazing! And the taste is even better. Very satisfied with this system, I used it for the dogs, drinking, cooking, coffee and haven’t run low. The system is 100% worth every penny.

This is an example of industrial design at its worst. It is cobbled together in the most amateurish way possible such that connecting things correctly is a hit and miss proposition. It works well when properly installed, but with individual elements needing different change intervals maintenance is a pia. A good product designer would do this much differently.

Best product ever. Good quality that produce excellent water

Spent a whole afternoon chasing leaks after installing this filter. Kept having to remove hoses, cutting off a bit, then reinserting them.

This is my second APEC water filter system I have purchased in the last 15 years. The first one ran great for many years. When the flow slowed, APEC support was awsome to help me get it working again. I just purchased the Hi-Flow model and it is amazing. It was easy to replace the old model and it seems like twice the flow of my original. Definitely would recommend!

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.
