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

Updated Nov 11, 2025After one year, we still haven't gotten the warning to change filter. We are two persons+2 cats with 3.6L/123oz of water fountain tank that needs to be changed every 10 - 15 days and I also cook and drink a lot.The machine still works perfectly fine. There's no leakage or malfunction occurred at all. Couldn't recommend this enough!------------Old reviewBackground 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.

I reached out to customer support after owning the unit for a year, as I noticed it was having trouble with water flow. Despite recently replacing the filter, water continued to trickle out very slowly, and sometimes the pump would make noise without any water actually coming out. On top of that, the machine would occasionally dispense water on its own, without being prompted. I even sent a video to customer support, but they claimed the unit was functioning as designed.For a $250 water filter, I would expect more reliable water flow and better control over the dispensing. While I can’t speak to the exact quality of the filtered water (since I don’t have testing tools), both my partner and I find the water tastes fine—definitely better than our city water. However, the ongoing water flow issue and the random dispensing are major concerns.New review 1/8/25:Our unit has officially failed it no longer dispenses properly. Sometimes you get 4 ounces of water sometimes you get 2 ounces of water with the 8 ounce setting. The pump will continue to make sounds as if it’s trying to pump out water, but no water dispenses.Old review below:If you haven’t purchased this unit yet, I would recommend trying other systems first. I was already on the fence before buying this product. I wish I had spent the money elsewhere.

You have to have some technological expertise to operate it. It takes visitors time to figure it out. Seems like getting water should be easier!

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.

I’ve been an APEC customer for a long time now. I’ve gotten most of my family onto the wagon too. So this is my third purchase of theirs. The last two moves we left behind our traditional and then our tankless systems for the new owners. This time we’ll be able to take our RO system with us!Operation is straight forward if you just follow directions. Like with any RO, make sure to properly flush new filters. The instant hot is fantastic for tea (mostly my wife). It dispenses water quickly, fills my 32oz bottle in no time. The taste is great, just like my experience with prior systems. Good looking system too on the countertop. Great product!
