APEC WATER - Reverse Osmosis Water Filter System (ROES-50) Essence Series - 5-Stage Filtration - 50 GPD - Removes 99.99% of Impurities - DIY Install - WQA Certified - Under Sink Reverse Osmosis System

Up until the pandemic, we had been using a large volume of bottled water every week. Since it has become risky to return to the store every time we are out of water, it seemed logical that a reverse osmosis system would mitigate that risk. Installation of the APEC system was not difficult, and I spread the work out over two afternoons. The first afternoon was spent boring a hole in our granite countertop. I used a Milwaukee 1" diamond hole saw purchased at our local home improvement store. I followed the recommendations found on YouTube for boring granite. I made a circular well around the drill site with plumbers putty to hold cooling water for the hole saw. This worked out well in terms of eliminating all of the granite dust and in keeping the hole saw cool. In keeping with the hole saw directions, the hole was started by boring at a 45 degree angle until the hole saw caught the granite. Then, the hole saw was carefully raised to vertical to complete the boring operation. The 1" hole was barely large enough to accommodate the air gap faucet that I purchased to replace the faucet that was supplied with the APEC RO unit. I would recommend boring a 1 1/4" hole. The faucet that I used was a Kingston Brass Concord Collection KSAG8198DL Reverse Osmosis System Filtration Water Air Gap Faucet. It has a long lasting Ceramic Disk Cartridge. I selected an air gap faucet to protect the APEC RO membrane from a drain backup. This is the same protection provided for dishwashers. Because the RO discharge water has to pass through the faucet air gap, the air gap inlet uses the supplied 1/4" tubing, but the air gap outlet uses 3/8" tubing. I ordered some John Guest 3/8" Food Grade Polyethylene Tubing from APEC. The discharge quick connect drain saddle supplied with the unit is 1/4" and that had to be replaced with a 3/8" drain saddle, also available from APEC. That requires that a 3/8" hole be drilled in the sink drain line. The drain tubing should be cut as short as possible while still providing serviceability. If the drain tubing forms a large loop below the level of the drain saddle, the air gap will not drain properly, and discharge water will leak from the air gap onto the countertop. Please note that this drain line requirement is only true when an air gap faucet is used. If the APEC supplied faucet is used, there will be no air gap and no air gap leak problem will occur. When connecting to the supply needle valve, it is important to remember to slide the compression nut over the supply tubing first, then the sleeve and tubing insert. Don't over-tighten the compression nut on the supply needle valve. All of the items described above can be ordered from Amazon. Installation went smoothly by following the detailed instructions found in the installation manual. After installation and system flush I measured dissolved solids of 19 ppm. I am told that anything under 100 ppm is excellent. With a new the calcium carbonate pH+ filter the water pH measured 9.3 which is alkaline. That's exactly what we were looking for. That pH is the same as is found in premium bottled waters. You would have to pay around $16.00 a gallon for those. The maintenance schedule is clearly defined in the installation manual, and the replacement intervals will depend upon the raw water quality. Whenever installing or replacing the filter elements, disposable gloves should be used in order to prevent the introduction of bacteria into the system. One thing that I did not find in the installation manual was an end-to-end sanitization procedure to be performed when it is time to replace all of the filters at roughly a 1 year interval. For that you will have to look for guidance elsewhere. Bacteria has a tendency to grow on charcoal media and that may be why APEC offers a UV lamp solution on some of their systems. APEC cautions not to inject chlorine into the system to clean it. That will destroy the RO membrane. However, whenever the filters are replaced, the housings should be thoroughly cleaned with soap and water. A few words about water pressure after reinstalling the system at our new home that is on a private well. There are times when the water pressure drops below 40 PSI and the RO system will run continuously for hours at a time. In order to mitigate this problem and to conserve water, we ordered a water driven permeate pump from APEC. APEC maintains that it will work to pressures as low as 30 PSI, and I will revise this review as soon as I have had an opportunity test it. The downside of any RO system is that is discharges more waste water than the amount of pure water it produces. That can increase the amount of water being drained into a septic system if there is one in use. If a water softener precedes the RO system, the salt that the RO system removes will be discharged into the sink drain. That will discharge some amount of salt into the septic tank. In such cases it may be better to discharge the RO system drain line outdoors and into a dry well along with effluent from the water softener. Draining brine into a septic system is never a good idea, and in many locales it is prohibited. One other problem that we experienced during reinstallation was that the needle valve on the water supply inlet side would not shut off. It appeared as though the needle valve had become pitted or corroded during its brief 4 months of use in Florida. It became necessary to replace the needle valve that is only available by buying a complete standard feed adapter. Next time it happens, I will buy a different style of adapter that incorporates a different type of valve such as a ball valve. These are available from other RO system suppliers on Amazon. A few words about radon. Since writing the original review, we have moved to a house that is on a private well. We moved the RO system with us. The water softener that is ahead of the RO system introduces sodium that is very easily removed by the RO system. Our well water also contains dissolved radon gas. The small charcoal filters that form a part of the RO system are not effective for removing radon gas from well water. If there is radon in the water, it should be removed before the the water enters the RO system. Then, the radon will be concentrated in a larger activated charcoal filter at a location far from the kitchen where the RO system is usually installed. Large activated charcoal tanks are available that will provide radon mitigation for the whole house provided that the dissolved radon concentration is less than 5,000 pCi/l - in our case 3,760 pCi/l. For dissolved radon levels greater than 5,000 pCi/l water aeration and outdoor venting is recommended, although these systems can also promote bacterial growth.

Absolutely love my APEC Water Systems ROES-50! The water tastes incredibly clean and fresh, and I feel confident knowing it’s thoroughly filtered. Installation was straightforward, and the system is very durable and well-built. I’ve noticed a huge improvement in my water quality compared to standard tap water, and it’s perfect for drinking, cooking, and even making coffee and tea. Highly recommend this RO system for anyone looking for reliable, high-quality water filtration! Functional work fine. Capacity hold a lot.

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!

This product literally changed my life! Back in the day I had to go the rite aid on a monthly basis, find Poland Spring boxes, haul them home in the trunk of my car, carry them to the second floor. Then same thing over and over again every month, carrying 5-6 boxes of Poland Spring up the stairs to the second floor. Also, I became a bit concerned with the fact that I throw out more than 100 plastic bottles per month. That is when I started doing my research. At first, I wanted to go with a BRITA pitcher (or PUR) but then after doing so much research I came to realization that those filters do make tap water better, but still not healthy enough for me and especially for my newborn. At first, under sink water systems were out of the question for me because I did not want to deal with finding a plumber, doing major plumbing overhaul in the house which I rent and pay top dollar for this. I was very fortunate to stumble upon this product and after reading all of the reviews I am very happy that I purchased it. The item comes in a big white box labeled APEC. Unboxing it was fairly easy so no need to write too much about it. The top layer of the package consists of 3 filters, then in a middle is 4th stage membrane filter and the piece that goes on top of the filters. Also, there is a wrench that helps tie the filter. There are also color coded tubes, faucet, adapter, drain saddle, teflon tape, etc. On the bottom there is another box with the water tank. In order to install the item you will need a drill, adjustable wrench and a screw driver. Installing 3 stage pre-filters is fairly easy, just follow the instruction as to which filter goes where and then screw them into the arrowhead using the included wrench to tighten the housing, but don't over tighten it too much. Installing the system under the sink is easy if you follow instructions carefully. One thing to note is that instructions are also available in the video format on youtube - just search for APEC water filter installation video. Although installing the item is fairly easy and the video shows that too, the difficult part is spending an hour or two under the sink, which can get very uncomfortable. Also, would be great to have someone help you because it is a bit difficult getting under the sink and out then back under again. The video makes it sound much easier that in real life. To install the feed water adapter you have to turn off the cold water (check that you turned off the cold water by turning on the faucet). I recommend turning off both hot and cold water just to be sure. Then you need to loosen the nut at any location and connect feed water adapter there - you can either loosen the nut at the top where the faucet is or at the bottom where the valve is, either is fine. Be careful - that adapter edges are very sharp and I cut my hand twice by accident. Also, don't forget to use teflon tape that is provided. Now the drain saddle - you need to use a specified size drill (refer to instructions) and drill a hole in the drain pipe. You need to drill in the horizontal pipe to avoid drain noise. If you do it correctly you will never hear the filter system working or making noises. Keep in mind that you need to apply pressure on the drill so that it goes through the pipe. Then you need to align the hole on the saddle to the hole on the pipe. I am not going to comment on installation of tubes so please refer to instructions - just don't want to confuse you. Last step is to install the faucet - you can either drill a hole in your counter but I used the spray hose hole instead. I removed spray hose (you disconnect it under the sink and pull it out, make sure that the water is turned off. Then I put the faucet that came with APEC through that hole. Once you are ready and everything is assembled, I suggest emptying at least 5 tanks of water. To do this, just wait till the tank is full and then open the faucet to let the water drip until it stops and repeat that 5 times. Now, in terms of water quality and taste. I got APEC ROES PH75 which is the same thing as ROES-50 but great tank output (75 vs. 50) and PH filter which you can either use or not use. There is a way to bypass it and you can call APEC support, they are great they can guide you through the process. For extra $20/$30 I decided to go with ROES PH75 - and I love it. You also get more output from your tank. And if you ever decide not to go with PH filter you can bypass it. At first, the water tasted a bit bitter to me, especially compared to Poland Spring but then either I got used to it or flashed a few tanks. Now the water taste is perfect, I absolutely love it. It replaced Poland Spring and I had it for a few months and everyone loves it. I also bough glass Life Factory bottles and love them too! I also bough HM Digital TDS (ppm) meter to check the water quality. Since this PH filter (6 stage) adds minerals back the ppm will not be zero, I am getting around 10. Tap water in NYC is pretty good at about 50 ppm and Poland Spring is roughly 20ppm. If you are considering PH75 or non-PH 50, I suggest going with PH75. It has better gallons per day output and comes with PH filter. If you don't like that filter you can easily bypass it. The water tastes great and this filter definitely improved by life. Thanks to APEC, Amazon and to all the reviewers who contributed to the great rating of this product, which in turn resulted in me buying it!

The APEC ROES-PH75 is a great reverse osmosis water system that I would recommend. - it uses standard 10" x 2.5" filters for sediment and carbon--the ones that require replacing most frequently--are available under many brand names at orange box retailer and others. This is my main reason for selecting this tank system over a tankless. The tankless was 2x the price but the filters even more. Seems like NO tankless use standard filters except for very low GPD models that are too slow for on-demand drinking water. - This system is not just WQA Gold Seal Certified but also meets NSF/ANSI 58 although that was tough to track down. - The quick connect tubes are easy to use; they leak a tiny bit during install but once in position they do not. - Comes with a spare set of 3 filters for sediment and carbon which was unexpected. - The provided faucet is good looking. - The first tank of water is cloudy but after that its clear. - I opted for the remineralization which i think makes it taste almost sweet? - The APEC support by email was great. I lost a stainless nut behind the cabinet and support was timely and good. I would like an valve for bypassing the remineralization (additive) filter? process for aquariums and simply to sample the difference.

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.

I’m thoroughly impressed with this product so far! After getting fed up with the chlorine taste in tap water, I realized just how noticeable it becomes once you stop drinking it. After several years of avoiding tap water, I can now smell the chlorine the moment I turn on the tap. I previously had a countertop filtration system from a Chinese brand, but it seems to have disappeared, and I couldn't find replacement filters. After doing some research, I chose APEC because they have a strong reputation and long-standing presence in the US market. For a while, I relied on bottled water, but then I realized just how costly it was to keep buying it regularly. That's when I decided to invest in this filtration system. The installation took a bit of time, as I had never fitted a system like this before, but once I got the hang of it, I realized it was actually a very straightforward setup. Everything works flawlessly, and there have been no leaks. Now, everyone in my household benefits from clean, great-tasting water, and the kids absolutely love it! The water has a smooth, fresh texture, and it makes a noticeable difference in teas, coffee, and even hot chocolate—everything seems to absorb better. The fittings are well-made, and the system feels sturdy and reliable. I was impressed with the shipping time, too, as it arrived from the US to the UK within a reasonable timeframe. Overall, this is a fantastic product, and I’m genuinely impressed with its performance. Kudos to the creators of this system!

The tap water we use at home had a strange smell.our home is 10 years old. My wife wasnt comformtable using it for drinking or cooking even after it goes through a regular filter. I bought the APEC ROES-50 system after much research. Both me and my wife are completely completely satisfied with this purchase. Water tatses awsome now after installing Apec RO and and there is no stink in the water either. Qyality at the Price: I had veen putting off buying an RO previously due to the cost involved with other systems. But Im gappy to report that Apec RO system delivers quality at a reasonable price. Installation: I also worried about the installation. But it was an easy DIY. Took me about 2 hours to complete. There are plenty of vidoes online and the instruction manual is detailed enough. The storage tank holds enough water for 3 adults through out the day. I could not hear any operating noise tha few people noted. The drain noise that some people noted can also be avoided if you follow the intructions properly . It fits under our kitchen sink faucet cabinet and neatly tucked away. I did not have to drill any holes in the counter top. I just replaced the spray hose with the RO faucet. Delivery and packaging: The product arrived in 3 days and packaging was good. No damage on delivery. The included faucet looks good and feels solid enough. Although it works on water pressure (not electricity), I found the stream of water to be ok and not weak. Water PPM: I tested the water from the RO and the equipment showed 6 ppm which is great and clean. Exactly what I expected out of the system. I would definitely recommend this system
