Review: Great product! High quality components. Can be installed without the tank. - 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 desertcart. 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.
Review: Awesome purchase! What a good system! - I previously have been using a Culligan H-83 system that came with our house maybe 16-18 years ago. The prior owners had it installed. That system worked ok, but never had enough water. It only had 3 stages too, a carbon, the membrane, and then a post carbon. I upgraded it by adding a wound pre-filter, and additional carbon post filters. It worked ok, other than the lack of the amount of water and the slow recovery time. But, the membranes were expensive. So this year I finally bit the bullet and ordered this system. It seems to recover fast, putting out more in an hour than my old system (my old one had a 50gpd membrane). When I purchased the system, I kept my old 4gal tank, used the included 4gal tank, and thinking I wanted to make sure I had plenty of water, I bought a 3rd 4 gallon tank. Holy macaroni batman, that wasn't necessary. Good thing it was only $49 for the tank! This a.m. I drained it completely and took probably 8 pitchers of water from the system and still didn't run out! Incredible. I am very pleased with the build quality. It is better than my Culligan system. The auto-shutoff works well too. I don't see too many ways they could improve this unit. I did not use the enclosed faucet or attach hardware, as I already had those. I think it'll be a great system. I bought the RO-90 instead of the RO-50 thinking that due to the longer Membrane life and longer filter life, that the $100 higher up front cost would probably pay itself back within 3 years, while also giving me 3-3.5gph recovery instead of 1.5gph recovery. So you get a better system and in the end you probably don't pay any more for it. I just wouldn't have bought the second tank, if I could do it all over again. Great system...took me maybe 30 minutes to get it all running, since I had the input and output hoses in place already and just needed to mount and organize. I like the included bracket. I know you can stand them on the floor or under the sink, but this is installed in my basement and it is very nice that I can wall mount it. Keeps it all out of the way real well. Very pleased.

## Questions & Answers

**Q: How often do the filters need replacing and what is the cost?**
A: I use a 1-3-5 year schedule and my filter works as well now as the day I installed it:
* Every year I replace the first three stages or the large vertical filters @$30-$50 if purchased separately
* Every three years I replace the fifth stage filter, horizontal filter on the top @$20-$30 if purchased separately
* Every five years I replace the fourth stage reverse osmosis filter @$30-$40 if purchased separately

You can usually get a discount and get all five stages for @$125-$135.

If you try to save money and not replace your filters as scheduled, you will probably foul up the stages behind it even faster.  For example, if you try to save money by not replacing the first three filter stages you will end up having to replace stages four and five way more often.  Which is actually a more expensive scenario.

I hope this helps you make a smart purchase or helps with your maintenance!

**Q: It says in the description that the unit removes flouride. Has anyone had a chance to measure the flouride levels in their water after filtering?**
A: The System is tested under the Water Quality Association to remove fluoride at 97.7% and the membrane itself was tested by the manufacturer Dow Filmtec to remove at a range of 90 to 97%

**Q: Can I hook it up to the ice maker on my fridge and use the included water faucet?**
A: Our system can be hooked up to the ice-maker on the fridge with proper connections. It can either be tee off so that it sends water to both the included faucet and the ice-maker or to the ice-maker or our included faucet by itself.

**Q: Does it require professional installation?  I have no idea what goes on under my sink!**
A: The system is packaged with the idea of do it yourself so you don't have to get professional help. Many of our customers were able to install it themselves by following the very comprehensive installation manual that we include in the package. We even have a video on youtube that shows how to install our system step by step. However, if you are not comfortable installing the system, any local plumber should have no trouble installing it for you in an hour or so at most.

### ⭐⭐⭐⭐⭐ Best water filtration system money can buy!
*by J***N on June 3, 2014*

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!
