APEC WATERTankless 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

The media could not be loaded. Background before buying APECI'm familiar with RO water and prefer it over anything else. I also used RO filter in Thailand and when I moved to USA I thought the water quality would be better so I wasn't looking for RO filter. I used tap water for cooking and drinking by filtering with Brita before but I personally hated it because there's still chlorine smell and honestly you can't trust water quality these days because there's a lot of contamination in it so Ineeded better filtration.Water qualityIt's RO so quality is as good as the bottled water. No chlorine smell. Water has taste but it has no sharp feeling when drinking. If you're worried that RO will get rid of minerals in the water, to be honest, you can get minerals from somewhere else - cooking, supplemental pills etc. Having access to non contaminated water is my priority.Filtration systemWhen you use up one cycle it takes 90 seconds to filter new cycle in it. It doesn't take long at all. The noise can be high but it never really bothers me as it's a quick process. The vdo I attached is of when it's filtering new tank.Suitable for 2 people with small animals. We are a couple and have 2 cats with big tank of water fountain. I also cook a lot. Bigger household should consider under the sink installation instead. We use tap water, it's NOT suitable for well water.Design is modern with decent materials. It's convenient especially those living in an apartment where you're not allowed to drill.

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.

I purchased a Amazon returned warehouse product. The unit itself was in new condition and was never installed. Everything was in manufacture packaging, including the filters. However, once I finished installation and plugged in the unit, it was DOA. I put a multi meter on the power supply and determined this external power supply was dead. I contacted APEC customer support through the Amazon manufacturer support link. After a day or so I received a response. APEC immediately shipped me a replacement power supply. Unit came to life and has been working flawlessly. APEC customer support was excellent in my experience.

This is exactly what we needed. We have the Apec 7 stage system in our home and love it. This summer we are in a rental with no filtered water. After a couple of weeks hauling 5 gallon jugs to and from the store I decided to explore countertop RO systems. We landed on this one because we've been so happy with the under sink system.We love it. The reservoir is large enough to supply plenty of drinking water, while not being too heavy to lift. I usually fill all of our containers first thing in the morning, and then top off the system to be used throughout the day on demand. It's working out great so far, and the unit actually looks very nice.
