Great system with quality components and very clear instructions. Great water quality but slow flow with 1/4 inch lines. Consider upgrading from this system's 1/4 inch final filter/tank/and faucet fittings to 3/8 inch. This option IS available in their premium system. Otherwise, filling a pitcher or pot takes a little while. (Posted on 3/17/2017)

My son installed our system and though having not experience with plumbing or setting up water system, he found the installation to be straight forward and the paper instructions well laid out and easy to understand. The water tastes fresh and clean. (Posted on 5/22/2016)

We just moved to Florida and the water quality is questionable here. After doing some research we decide to purchase an APEC system to improve our water quality. We bought two of them and they came with everything you need to install them with. Instructions were very clear and easy to understand. It took us about one and half hour to install.the first one and one hour to install the another one. All you need is a wrench or pliers.

Although the system doesn’t leave much room for other stuff due to the tank size, it produces high quality water with low TDS and it operates very quiet as well. The water tastes very different compared to tap water. It has a nice fresh crisp taste to it. We use to drink bottle water mostly and after installed this system, We no longer need to buy any of the bottled water.

I feel fully satisfied with this product and would like to recommend this system to anyone because it appears to function as advertised. (Posted on 4/26/2016)

After the unit was installed, I noticed that water flowed very slowly. My TDS meter showed about 28 vs. my tap water at 350 ppm. I knew the water quality was good. (Posted on 4/5/2016)

It was easy to install and the water is great. The only drawback is the faucet looks and feels fragile but it works great. (Posted on 3/29/2016)

Relatively easy to install, water tastes amazing…. Only 1 week in use, but so far we are thrilled to have clear, chlorine and fluoride free water… Not to mention free of other unknowns! (Posted on 3/19/2016)

Installation wasn't too bad, I installed the system within about 90 mins. My wife and I were very surprised. We were buying drinking water for years, I will say that this water tastes almost exactly like smart water and better than any other bottled water I have tried, let alone our city water. We will break even in about 3 months and then this system will pay for itself over and over. (Posted on 3/6/2016)

Great filtration system and easy to install by the plumber… (I am not handy). Does take a lot of space under the sink but we feel it is worth it. (Posted on 2/12/2016)

I had to call the customer support only once since my number of filters didn’t look exactly like the photo in the installation manual, their customer support was awesome and they quickly resolved my confusion. This system makes my tap water taste wonderful. I am happy with the system purchased from APEC. (Posted on 2/8/2016)

This system has exceeded my expectations. Our TDS meter showed that our water had 260 ppm rating, after installed the APEC system our water dropped down to a super low 16 ppm. (Posted on 1/29/2016)

It was an outstanding unit, fits under the sink with room to spare. The water does tastes differently from tap water and it works well. I am very impressed. (Posted on 1/17/2016)

I am very impressed with the high quality of the materials from the filters down to the connectors. The installation was easy and the user’s manual is very well written. I had no problems in setting up the system and using it (Posted on 12/31/2015)

This is the best investment for your family’s health. I have had this water filtering system a year ago. It was made in America, quick shipping and with the easy instruction I had done the installation for two hours. The water tastes great and it reduced 95% in TDS. (Posted on 12/20/2015)

I had a few under the sink filters in the past but none can compare to this one. The water we get is horrible which regularly testes at 550 to 600 TDS, but with this system, my filtered water went down to about 34 that is good to drink and tastes get much better. (Posted on 12/14/2015)

It’s a great product. I had trouble installing it and called the support. They were very helpful and friendly. The system works perfectly and water tastes great. (Posted on 11/11/2015)

I am so glad that I bought this water filtering system. Our water was terrible without using it. We bought the TDS meter and found out that water from this system is much cleaner than some of the bottled water. (Posted on 11/1/2015)

I installed this in an hour or so, and I love it. I watched the installation video on YouTube. Water tastes great, TDS went from hundreds to 29, I would buy it again. (Posted on 10/29/2015)

I love this filter. It was easy to install and tastes great (Posted on 10/23/2015)

I had to call the company for a couple of times with questions. Each time, I got someone on the line right away and they were helpful and pleasant. I feel good about this purchase and I installed my system successfully. (Posted on 10/1/2015)

I received and installed this RO unit yesterday. I am so far 100% satisfied. The unit arrived very well packaged with installation instructions included. I completed this in just over an hour and the water tastes delicious. I actually smiled after my first sip. You can immediately tell this is good, clean and fresh water. I would recommend this system to my friends and family. (Posted on 9/17/2015)

I purchased the ROES-PPH75 and I'm glad I did, I have also noticed that I drink a lot more water after I install a water filter system. (Posted on 9/13/2015)

A friend of mine mentioned the APEC system and what a good value for quality it was; I was doubted about this filter’s function. After been using it for 6 months and I was glad that I made a right decision. (Posted on 8/18/2015)

Installation was pretty straight forward with clear and concise instructions. Installed it in about an hour. Love the water and do not have to carry any bottled water anymore.

The water from this unit is pretty much tasteless to me, which is ideal since tap water tastes awful. We also added a line to the fridge ice maker so our ice is purified too. It was easy to install in our home and we have used it for three months with no problems. (Posted on 7/13/2015)

It is very easy to install, the water tastes good. (Posted on 7/3/2015)

I finished installing my RO system today. The only thing under my sink is the filtered water line coming up to the faucet. I had a plumber installed a “T” connection in the crawlspace for the supply line. The water’s quality is pretty good and taste is great too. (Posted on 6/19/2015)

This is our secondary family water filter ( Our primary one is the 90 GPD one from the same company.) and this works just as well as the first one! No smell no weird chemical taste just pure tasty water! If you want a high quality filter I suggest you to buy this one. (Posted on 6/8/2015)

The install was rater painless. I needed help connecting the drain line to my plumbing and their tech support quickly sent me a different part. Thanks. (Posted on 5/17/2015)

The water quality is great. My wife is very picky about water and she enjoys this. The system provides plenty of water to run to refrigerator, ice maker, and faucet for our family. (Posted on 5/11/2015)

Don’t ever buy a bottle of water again, this system is a great way to save money for your household and live in a healthier lifestyle. The water quality is amazing pure, which you can use your TDS meter to test for it. The water tastes much better than the tap water. (Posted on 4/23/2015)

APEC delivers the purest, best tasting, and most economic filters that once can find. Our health is our priority especially with two young toddlers at home who love to drink water. I now can sleep soundly knowing that our family is safe in drinking healthy water because the system filtered 99% of harmful pollutants, hard metals, bacteria, fluoride, etc. highly recommend this system. (Posted on 3/12/2015)

My wife claimed our city water tasted funny so we had spent a long time to research about the filter and we finally found this one. I thought it was a fair price and we installed it pretty easy. It took us about 1 ½ hours to install. I was very surprised that the water taste much better. I highly recommend this product. (Posted on 3/6/2015)

I am very happy with this purchase. The system works well and very quiet. Installation needed prior planning for both size requirements and accessibility. Since we have a very deep kitchen sink, getting to a small area behind to install the faucet took me the most of the time. (Posted on 2/12/2015)

It works great, but it seems there is no enough water to supply for a 4 people family who drinks exclusively water. So, a little bit larger reservoir would be helpful. Water tastes great and refreshing. Overall it had done a great job. (Posted on 1/31/2015)

I love the filter and the water tastes great. Although the unit is much bigger than I thought it will be and I lost much of my under sink storage, I am still happy because the water is so much cleaner. (Posted on 1/9/2015)

The system delivered as promised and the system was very easy to install. The instructions came with detailed diagrams and host of information about the future replacement of the filters. The system has been up and running for almost two month now and the water tastes great. (Posted on 12/21/2014)
