We LOVE this RO system, we bought and returned the big berkley water filter for our horrible Las Vegas water and was sadly disappointed in what the Berkley was able to do. After a ton of research on the web and reading reviews we decided to go with APEC because you never know what you will end up with some poorly made system in china system that might break a valve and flood your home while your at work. The clean sweet flavor of good tasting clean water this system delivers is amazing. It reminds me of the water I drank from the tap when I was a kid back in the 70’s....Fresh and clean! Been using this system for 2 weeks and I will never go back to buying bottled water again. They also give you an extra set of filters and water tester which comes in handy to test the quality and to know when to replace the filters which by the way is really easy to do. To clean the system and sanitize it a friend who installed about 500 RO systems recommended once a year when you replace the filters to pour a few capfuls of hydrogen peroxide into the 3 empty chambers and clean em out with the peroxide and water solution to get rid of any crud (2 carbon, 1 sediment) then disconnect the tube where it feeds into 3 gallon tank and suck out a little water from the feeder tube and replace that water with a little bit of peroxide and re-connect it to the tank so that the peroxide goes into the tank, thank you APEC! Update 3/16/2017: Still amazing water coming out with the same filters after 2 years, I tested the water purity with the electronic gizmo they give you to test purity and its still the same! The only issue I have had is the faucet on top of the sink leaks a little when you open it for water to come out but I was a little bit too hard on it with putting to much pressure on the valve when I opened the faucet ... it was MY Fault... just me being impatient...lol. I called customer support and they offered a new one for half the price on amazon. Incredible company, first class support, and the best tasting water ever! Read more

Great product! Very high quality components. Easy to install. Great customer service. My local municipal water has TDS around 330. The filtered water comes out around 10 and tastes great! I am using the system without the tank. You can do this by modify the tubing and connect the filtered output of the ro-membrane to the 5th stage filter directly (bypass/remove the T that feeds the tank and the 5th stage filter, very easy with quick connect used on the APEC system). I use glass pitchers to hold the water. It takes about 5 minutes for the RO-90 to fill up a 2-quart ikea glass pitcher (half gallon). Why would you want to use the system without the tank? To get the best tasting water and not have to worry about whether the tank material is safe or not. For the RO tank to work, the water has to be held inside a bladder in the tank, so that the air pressure around the bladder can push the water out when you need it. For this to work, the bladder has to be a flexible material that can expand and shrink as needed. The type of food grade material that is suitable for this purpose is limited. The material being used is polypropylene and butyl. Now, while this should be a safe material to use, it does add an after taste to the water, especially if the water has been sitting in the tank for a while. That's why there's a 5th stage carbon filter, to filter out the tank taste. But having an after taste that needs to be filtered out does imply that the tank material affects the water. If you don't believe me, just read the Watts RO system reviews on amazon. Many are complaining about plastic water taste. The bladder also ages, and has an expected life of 8-10 years due to all the expansion and contraction. While I am sure the tank material used by APEC is better than the one in the Watts system, why get yourself into this situation at all? Just bypass the tank and store the filtered water in a glass pitcher. Glass is arguably the best material on earth to hold purified drinking water, and will not leach into or affect the water taste in any way. Bypassing the tank also allows you to have explicitly control over when to produce the filtered water. Tap water is generally better quality in the evening when everyone around is also using water. It is less good in the morning when the water has been sitting idle in aging pipes for hours. This is why when your local municipal utility conducts water tests, they usually flush out the water for a few minutes. My TDS test confirms this. Filtered water in late evening has TDS less than 10, while in early morning is around 20-25. I did contact APEC system and was very impressed by their customer support. Read more

Replaced a system that went bad. Easy Install - local company wanted $699 so I tried it myself. I'm NOT handy but all the harder work was already done at my house for the other system (drain hole to drain pipe/spigot install in the countertop/t connector and hose to my refrigerator). I feel I could have done a brand new install myself just watching the youtube videos that are easy to find. This was so inexpensive so I ordered the kit. Everything went smoothly except the prior install had a 3/8" hose coming from the spigot T valve because the prior system had a 3/8" connector on the system itself. Nighttime dash to lowes for a (SharkBite Push to Connect 3/8 in. PTC X 1/4 in. D PTC Polypropylene Coupling) and some extra 1/4" hose just in case... and I'm making water! Read more
