"It's good to enjoy a refreshing glass of water without a metallic after taste. I also like the fact I can enjoy my morning coffee and there is no white residue in the water reservoir."
"These filters are amazing! We’ve had this system for a little over 2 years now and have definitely seen and tasted a major improvement in our drinking water. The only issue I have with this system is the fact that the filter 4 housing is extremely hard to get open after not having changed the filler in the time we’ve had it and because there’s no real way to get a good grip on the housing unless you have gigantic hands or an extra set of hands holding it while one person unlocks it. It’s really annoying. Thankfully it was able to be opened after 2-3 hours of trying. Even if there’s supposed to be pressure released from this there is no real way to do that unless it’s opened."
"I feel safe, knowing that these filters are keeping my water clean."
"Easy install,easy upkeep."
"I have trusted APEC system for ten years. I live in New Mexico where the water is hard with a lot of minerals. Since I started using the RO Apec syste, friends and family compliment the taste of our home water and they take gallons of our water to their home. Filters last long time and support has been very helpful. I got a leak for the first time after ten years. . . the cap of one of the canisters had a tiny crack. . . probably because in the last change of filters I overtighten one of the caps. Anyway, with the advice of Apec support I replaced the "system head" and everything went back to normal!"
"I am a little disappointed in the performance of the new filters. The water from the old filters was coming out at 30 PPM, now the water from the new filters is coming out at 70 PPM . Was hoping the PPM would be less. But I guess it's still better than the 650 PPM rural water going in."
"Great customer service"
"is my second purchase of this under-counter system. I had one 15 years ago in a former home. It performs well, was easy to install, and Customer Support is great if you have any questions. Everyone is friendly. My daughter has the same unit and happy with her's as well. Our previous system aged out after 10 years. The tank needed to be changed and it was just as easy to convert the system back to a Roes-50."
"This works!! Don’t hesitate to get one. The sediment found on the old filters was disgusting… and we have RO filtered city water."
"This product works well. . . thanks for selling to us directly rather than going thru a 3rd party!!!"
