APEC Water Systems ROES-50 Essence Series Top Tier 5-Stage WQA Certified Ultra Safe Reverse Osmosis Drinking Water Filter System 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.

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.

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.

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. =)

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.

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.

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