Installation was easy if you are handy with plumbing. Review: APEC Water Systems changed my life! - 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, desertcart and to all the reviewers who contributed to the great rating of this product, which in turn resulted in me buying it! ## Features - Supreme quality – designed and engineered with only premium components to ensure high quality filtration and a durable reverse osmosis system for years - This 75 GPD 6-stage system ROES-PH75 is guaranteed to remove up to 99% of impurities such as Chlorine, Taste, Odor, VOCs, as well as harmful Fluoride, Arsenic, Lead, Heavy Metals and 1000 plus impurities.

We use the same technology as other major bottling plants use to filter water. RO systems purify water daily in your home which is fresher and healthier compared to water that has been sitting in plastic bottles. **Q: How effective is Reverse Osmosis filtration compared to other methods?** A: RO is the most convenient and effective method of water filtration. It filters water by squeezing water through a semi-permeable membrane, which is equalse to 0.00000004 inch! This is the technology used to make bottled water. **Q: What is the WQA and what are the benefits of purchasing a certified system?** A: To receive WQA Gold Seal certification, a RO system must be constructed to meet strict public health standards and pass weeks of rigorous testing for material and parts safety, structural integrity, and contaminant rejection performance. **Q: What is the size of the product, and if I move, can I remove the system to bring with me?** A: The dimensions are 17.5"H x 15.5"L x 5.25"W, and the tank is 11"W x 15"H. This system is very easy to uninstall. Just close the water inlet needle shut off, take off the water inlet tubing, and take off the whole system in 5 minutes. **Q: How often do I need to replace the filters?** A: The filtration process is optimized to protect the RO membrane, so the prefilters (the 3 filters before the membrane) can last between 6-12 months, and the RO membrane & post-filters can last between 12-24 months depending on incoming water quality. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great tasting water *by S***L on July 17, 2026* Great product and very good tasting water, a lot better than fridge water .

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! ### ⭐⭐⭐⭐⭐ Easy to install and great water taste *by R***B on May 10, 2020* 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. ## Frequently Bought Together - APEC Water Systems ROES-PH75 Essence Series Top Tier Alkaline Mineral pH+ 75 GPD 6-Stage Certified Ultra Safe Reverse Osmosis Drinking Water Filter System - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(Β°C,Β°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc - HoneForest Water Quality Tester, Accurate and Reliable, TDS Meter, EC Meter & Temperature Meter 3 in 1, 0-9990ppm, Ideal Water Test Meter for Drinking Water, Aquariums, etc. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/7626783-apec-water-roes-ph75-6-stage-under-sink-ro-system](https://www.desertcart.pl/products/7626783-apec-water-roes-ph75-6-stage-under-sink-ro-system) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-08-18*
