APEC Water ROES-50X 5-Stage Under Sink Reverse Osmosis Water Filter System, NSF Certified 372 & 58, 50 GPD, with Extra High Capacity Pre-Filter Set Stage 1-3

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.

JUST PUT THIS IN 5/6/26 AND LOVE IT ALREADY. WATER TASTE GREAT EASY TO USE AND REPLACE FILTERS. MADE OF DURABLE PLASTIC. GREAT FILTRATION SYSTEM.

We installed this system about a month ago. Instructions were clear, it was an easy project. Our TDS dropped from mid-400's in our tap water to about 40, easily 90%. I had noticed the reviews mentioning water leaks at connections, but I found them to be tight if put together right. Still, protection is always good, so I installed a very nice little automatic safety shut off valve by a company called Savant. Here's the link- https://www.amazon.com/gp/product/B08BCNX42F/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Always pleased to get things that work! UPDATE 18 Months in use! The system has been flawless, no leaks, no malfunctions and we are still on the original filter set. Latest tests on the water quality compared to our tap water are still showing around 95% reduction in TDS, total dissovled solids. One of the reasons for the installation in the beginning was the discovery of just what was in the TDS of municipal tap water. Your local water company will have that data, I found mine easily online... and found arsenic, lead and a host of unhealthy things were allowed up a limit. Our tap water runs 450-500 PPM. The RO cuts that to the 25-30 range, and we use it for anything that will wind up in our bodies; drinks, cooking and so on. It tastes better too. Overall it has been a very good choice and investment.

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. =)

Really good. This is my second one (new house). Install is straightforward, the instructions are clear and hoses are color coordinated. The only hard part would be drilling through your countertop, but I have always just used the pre-existing hole from those crappy old soap dispensers. You also have to drill a 1/4” hole in your drain pipe. Do NOT do this after the p-trap, it must be before. Installation took me maybe 2 hours, with a large portion of that just dedicated to testing for leaks along the way, and the awkward work space making simple tasks like tightening a nut more challenging. Really makes a big difference in the water quality. The water is perfect. The filter is not dead silent, but very quiet and nothing you would notice once the cabinet is closed. 100x quieter than your refrigerator. Pressure is decent as long as the tank has some water in it. Takes 2-3 hours to fill the tank, and a little over 5 minutes to drain it. I never have any problem running out of water with normal use. It’s pretty large so make sure you have space. The instructions do state that the tank can be placed sideways and that the filters themselves can be stood upright rather than mounted if desired. We figured we were spending $60/month on bottled water, so this pays for itself in three months, and saves a lot of unnecessary plastic waste from entering landfills and oceans. Note: do NOT touch the blue thing on the side of the tank. It looks like a disposable cap for shipping but it is actually a vital air valve.

Great tasting water once you get the filters purged ! Our water is so crisp and clean tasting this system works great ! Best water ever I highly recommend! For the price you can't beat it plus it comes with extra filters ! Me and my oldest son are the water drinkers in this house and now my whole household loves drinking water and that says a lot for toddlers ! If your thinking about getting a water filtration system this one has a great price point and instillation isn't bad at all had it up and running in about 1 hr ! But my uncle did install it and he works for a watersoftner company so for the complete novice it might take 2 hrs ? He recommended this one to me and has it in his own home . No regrets!

Within 1 month of installation, the tank started leaking from the top valve. This was not an installation issue — it appears to be a defective component. The leak went unnoticed and caused water damage to the cabinet under the sink. This is unacceptable for a product designed to handle water pressure. Now I’m dealing with repair costs for something that should not have failed this early. Expecting refund/replacement and accountability from the manufacturer.

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.

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

Good water filter system it works as intended and I have no complaints. Would be 5 starts of it filtered faster it’s fine if you only use it for fridge water and ice cubes but too slow to use for watering you garden you only get about 6 litres of filtered water then you have to wait for the tank to refill.
