APEC Tankless RO Water Filter System ROTL-AIO - Four-in-One Premium Reverse Osmosis Water Filtration, 2:1 Pure to Drain, Filters Fluoride, Heavy Metals, 1K+ Impurities, Easy DIY Install & Care

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.

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.

First of all. I've notice they are combining reviews from all their models. This review is for the APEC Tankless RO Water Filter System ROTL-AIO.-The water taste is good but not great, in my opinion. Still much better than the water straight from the tap. Our water is VERY hard, so this might be part of the issue. Might install a whole house water softener to fix this.-Its a tankless unit, so it uses a pump that's a bit noisy but not horribly loud.-Installation wasn't hard. However, the included install kit comes with really short water lines. I had to make a trip to the hardware store for longer lines. I got enough to replace the kit lines completely so I didn't have any splices that could leak. Make sure you get the food grade water lines.-This unit needs to be plugged in. The power cord stretches out to about 5 feet so Had no issues, but make sure you account for power when getting this unit.I'm going to get another reverse osmosis unit for my refrigerator, but I will be looking for one that has a bit better taste. Maybe a unit that has a remineralization option and UV light.I'll be keeping this unit for my sink and I believe it will be great for cooking and filling larger jugs for tea and other drink mixes.
