APEC ROCT-Plus Countertop Reverse Osmosis System, Efficient RO Filter 3:1 Pure to Drain, Instant Hot Water ± 2° for Tea, UV Water Filtration

Recommend! It is a lot more user friendly than the 3 stage Osmosis system this replaced! The replacement filter is also much less money than the replacement filters for our original 3 stage system. A little noisy when you are running it or when it occasionally filters, but not bothersome. No issues. You may need a plumber to do the initial install depending on your set up under your sink and how comfortable you are with DIY. Also recommend to make sure you have enough room (height, depth, and width), and an outlet to plug it into under your sink before purchasing. A worthy option if you are looking at this type of Reverse Osmosis system.

Updated:I've used this for over a year, and it stopped working properly after about 6 months. After turning on the water, it would go a bit, then I would turn it off, and it would start making pumping noises. This eventually led to the unit stopping altogether. In order to get it to start again I had to unplug and replug it. I contacted APEC support. They told me to reset the unit, so I did. Not only did it NOT fix the problem, now the unit reset the filter, and the red light is blinking instead of the blue one from before. The water itself has also lost PPM quite a bit, from my previous review it was 25-40, now it's 57 - 75, and the water taste is very different. I went back and forth with APEC for a couple weeks, the best they would do is send me a new filter. But that doesn't fix the pumping problem that continues, sometimes for 5 minutes, pumping every 3 seconds in an interval. It's not the "alarm" because the none of the alarm levels act this way. I would ABSOLUTELY pass this unit by. It's affordable, but if something goes wrong like it did in my case, APEC isn't there to help, and you're left with a unit that's completely worthless.OLD REVIEW: I've been using this RO system for about a month now and it's worked pretty well. The water tastes great, and I can now utilize higher quality water for cooking, which I've wanted to do for a long time.Some notes about install. You need power for this system. I wasn't sure I had it, but any regular plug will do, I had to run an extension cable under the sink but I made it work.When installing the unit came with little white insert caps where the hoses (red, blue, etc) go. The instructions didn't say what to do with these or how to remove them, but these caps MUST be removed to put the hoses in.Also you have to drill into the drain pipe for the waste water to drain. They have you seal and screw the hose to the drain pipe, but it's important to know that you will need to drill into the existing plumbing, because you need the drill, and you need to be okay with doing that. If you remove the system, you'll need to seal that hole laterOnce out together and setup, you'll start the system. It started flashing red once I turned it on. Leave the system running until the system displays a blue light. Afterwards the water is safe to drink.The ppm on my water on the tap is around 270 - 290. Running through the RO system it's between 25 - 40 depending on how long I let the system run ahead of time.Was worth the purchase, and I haven't hesitated to recommend this model to friends.

It's an RO filter that works on demand! It does make some noise, but not a massive amount and only while it runs. No leaks, install was a little easier than other systems. Very happy with the space savings and not having to wait for water.After a year I had some problems with the faucet splitting into two streams. Ended up just being some gunk built up next to the end of the faucet. If that happens to anyone try cleaning the end with a toothpick.

I bought this APEC tankless unit to replace an older APEC model with a tank and 5 filters. The water on the new unit tastes good but not quite as good as with the old tankless model. This unit was installed by my plumber. It looks great inside the cabinet and I’m happy to no longer struggle to replace the 5 filters. I will sacrifice a bit of water quality for the convenience of this tankless unit. I don’t find the sound of the motor bothersome. It’s about the same noise level as the nearby Subzero refrigerator. The plumber had to put a fitting on the blue tubing so it would accept my faucet which is a water filter faucet that matches the other finishes in my kitchen. APEC could provide more instruction on installing with customers own faucet and provide the piece needed. Also, the water had to run a long time for the flashing red light to turn solid blue. Longer than the 30 minutes listed, more like 40 minutes. Overall, I like the unit and would buy again.

The media could not be loaded. I purchased this for my parents. They live in an apartment and are not allowed to install an under sink water system. So far it works great and we all love it so so much! It is very compact, fits the kitchen counter perfectly, and the quality looks good too. It is so easy to use, just add the tap water in the pitcher, then press one button, and filtered water will come out! You can choose room temperature or hot water for coffee or tea. And the most important part is the water tastes great! One added benefit for us is that since it is portable, we can take it with us on our camping trips! Strongly recommend this system to anyone that has the needs like us.
