APEC Water ROES-50X, 5-Stage Under Sink RO System, Extra Filters, 50 GPD

I couldn’t be more pleased with the APEC ROES-50 Essence Series 5-Stage Reverse Osmosis System. From installation to performance, this system has exceeded my expectations. The water quality is outstanding—crystal clear, with no taste of chlorine or impurities. It’s reassuring to know that the water my family is drinking is ultra-pure and safe. The installation was straightforward, even for someone like me who isn’t particularly handy. The instructions were clear, and all the necessary parts were included. The pre-filter set (Stages 1-3) has excellent capacity and is very easy to replace when needed. I appreciate that APEC’s filters are WQA-certified, giving me peace of mind about the quality. One of the best things about this system is how much money it has saved us—we no longer need to buy bottled water, and the water tastes just as good, if not better! The tank fills quickly, and the system is quiet in operation. Overall, it’s a great investment, and I highly recommend it to anyone looking for reliable, high-quality water filtration at home.

I installed this Reverse Osmosis water filtration system in my home about a year ago. Most people keep their pressure tank and filters under the kitchen sink, but I mounted mine to the basement wall just below the kitchen—so I could save that valuable kitchen cabinet space under the sink. I am a plumber and wanted a fairly priced RO system and this is it! The install was fairly easy, because most of the connections are just push-to-connect with 3/8” or 1/4” plastic hoses and fittings. One caveat I have is that the threaded connections between the three main filter housings were leaking VERY SLOWLY when I first installed everything. I had to turn the water off, remove the filter housings, and apply Teflon tape and pipe thread sealant to the threads between the housings. Then I reassembled and there have been no leaks. We use the clean water for normal drinking water, better water for tea/coffee/espresso, and if someone in our household has a bad cold, we can use the RO water with a Netti-pot to clean sinuses out. Most of the filters only need to be changed every 2 years or more. I wrote a note below the filters with the install date. I also successfully got the 2 year manufacturer warranty confirmed through their website, which is a nice free feature.

I highly recommend APEC WATER ROES-50/75 Essence Series systems for ease of use, affordability, flexible, and excellent support. I don't usually give a 5 start perfect review. This company and system honestly deserves it (so far after 8 months at least). REASON My need was for a home filtration for four people. I was looking for a simple system that is small to medium size for under my compact sink cabinet and not super expensive for initial purchase nor filter replacements. APEC hits all the marks and then some. After install my TDS reading went from 185 down to 22 (with some increase over time to 32 as filters get used)! SUPER EASY I had an existing two-stage filter with a drinking water tap. The APEC kit fit perfectly and came with extra bits that allowed me to also attach an existing secondary line to my ice maker. All the tubing was plentiful and plugged in easily to the filters and other pieces with zero leaks. It all just worked, even drilling into my drain pipe was easy to attach the waste tube with included leak-proof parts. Instructions were simple and easily read with large color images. NICE ADDITIONS I purchased the ROES-50 kit that uses five stages. I later added a sixth stage to re-mineralize because the water was on the super clean-tasting side which didn’t do any favors for my morning coffee brew. APEC offered an easy add-on kit that included the filter plus extras needed to connect and mount. When I received the kit, it was missing the clips for mounting. I sent an email and they immediately mailed me the parts, no questions asked. MANY SALE$ I also signed up for the mail list and am satisfied to see all of the sales they have for replacement filters. There aren’t too many messages either. This system is easily less expensive than those from other manufacturers. Convenient six or twelve month subscriptions bring the price down further. EXCELLENT SUPPORT After about 8 months, I had a pressure problem that turned out to be a silly user error on my part. Before I figured out what went wrong on my end, I emailed APEC for help. They were extremely responsive AND helpful with multiple clear step guides that were easy to follow. In short, I’d recommend APEC WATER products to most anyone.

The water is amazing after installing the RO system. It was pretty straight forward and easy to install. I really wish they would design it differently so that there aren't so many connections throughout the system. There are just way too many places for a leak to spring up. After installing the whole system and also adding a splitter so I could have filtered ice as well, I tested the system and noticed no leaks on any of the lines that I connected myself, however there was a pretty bad leak on one of the factory 1/4 inch OD lines that came already attached to the filter housing. I made a new piece, which I made longer so it could loop because the factory piece was short and had to bend awkwardly in between the connections, which I assume played a part in making it leak. So be prepared to test it out beforehand over a plastic bin or towels because it may leak out of the box. Also wouldn't hurt to order extra 1/4 inch OD line and a cutter for it, and may also need to order a splitter if you want to run a line to your icemaker. Also takes a 1/2 inch drill bit for the hole to add the extra faucet. So far I have zero complaints about the water though. The water rocks and tastes great. Finally able to stay hydrated without being dependent on bottled water. =)

Its my second buy over 10 years period. This 5 filter system is good enough. Easy installation and awesome quality. It measures under 12 ppm which is excellent quality even sweet taste somehow. Buy this. No complaints guaranteed!!

I was a little intimidated at first about getting this to work the way I wanted to, but it was a really simple set up. I actually have this in a closet in my basement and going up to my fridge on the first floor. I just ordered extra length of 1/4" O.D. tubing so it could run further. The stock kit comes with enough for you to install directly under the sink. Some parts I recommend updating is the feed water adapter that attaches the system directly to your water supply. I ordered a brass one instead and its been working out great. Specifically this one --> www.amazon.com/dp/B09Z7NTZPG To attach quick connect to the ice maker/fridge, I got these and it's been working great --> www.amazon.com/dp/B0BW1TRRP6 I also added a permeate pump so the system runs more efficiently (doesn't waste as much water to produce clean water) --> www.amazon.com/dp/B00I3VKHSI I then also added the alkaline stage which was easy enough to do to add some minerals back to the water --> www.amazon.com/dp/B01CUS46DG I'd also recommend getting some wireless leak detectors (I got the Govee ones) just for peace of mind. That way if the system leaks for any reason, you'll know right away. All said and done, the water is fantastic. My tap water wasn't terrible, but it wasn't great either. Testing the tap and testing the RO treated water, I can see a very clear difference. Ph is more balanced and showing no signs of contaminants. I can also taste the difference too. My ice and water kind of left a weird aftertaste in your mouth and now it doesn't. Pure, clean water. This kit was very easy to get going and if you have even a few brain cells, you should be able to just look at the diagram and understand how it works. Instructions were very helpful though. For the price, this is fantastic. Just keep in mind its limited to how much water it can provide. I originally thought I could have this hooked up to my sink, dishwasher, etc, but it's not like that. There are more expensive system out there that could handle that kind of load. This is really to provide clean water to one or two sources through the provided faucet and an ice maker. The system is simple and very easy to modify if you'd like to do so.

I've been using this reverse osmosis system for about three months now, and I can honestly say it's one of the best home upgrades I’ve made. The installation took a bit of time (about 1.5 hours), but the instructions were clear and all the parts were well organized. If you're even a little handy, you’ll be fine. Once set up, the difference in water quality was immediate. No more chlorine taste or weird odors—just super clean, fresh-tasting water. I use it for drinking, cooking, and even brewing coffee, and everything tastes noticeably better. It’s also been great not having to lug home bottled water anymore. The tank fills fairly quickly, and pressure is good. I also appreciate that it comes with a extra sets of filters. Only minor downside is the space it takes up under the sink, but that’s to be expected with an RO system. Still well worth the trade-off for the quality of water you get. Highly recommend if you're looking to ditch bottled water and want peace of mind about what you're drinking.

The connection between the housing of Filter No. 3 and its base is leaking, and there is a crack inside the No. 3 filter base. As a result, a large amount of water leaked out and severely damaged the flooring in my kitchen, dining room, and living room. This damage was caused by a quality defect in your product, so I believe your company should be responsible for compensating me for the resulting damages and repair costs！

The set up was very simple because of detailed written instructions English instructions and diagrams. The system works very well and will highly recommend it.

I live in an area where the city water is questionable. It could very much be a placebo, but the water tastes good without any smell. No leakage yet.

everything was great worked perfect and instructions were clear, although you can tell its budget model with some cheaper feeling plastics and a faucet handle that gets loose easily although easily tightens

Fairly easy to install water seem to have something in it representative said it's air it did dissipate water tastes like nothing needed to filter out the water softener salt

Very happy with the purchase. it was easy to install and the result is very satisfying.
