"Works well. Arrived on pallet in proper orientation, standing up. Softener was installed 9 months after arrive, and no issues. I would purchase this item again."
"We are loving not having to haul heavy jugs of water. The water tastes great and is very convenient."
"We've had RO-Hi for 6 years now and we are very happy and glad we installed one. You can actually taste the difference between RO water and bottled water -- it taste fresh and clean, there's a certain sweetness. It gives us a peace of mind that we are drinking clean water -- I don't smell or taste the chlorine anymore. I am giving it only 3 stars not because of the quality of the RO system but for the customer service. I made a mistake of ordering the RO system instead of just the filter, the representative that I spoke did not really help me with the return, instead he just kept discouraging me from returing the system."
"I ordered a new RO-HI water filter to replace an older one and wanted higher water flow. Cannot say the new one was much more flow. Hope that will improve as we use it more. My original order had “Order Protection” added to the order for $8. 35. Not sure how this was added to my order. I called to inquire and asked why I needed it and the person I talked to could not give me a reason as to why I would need this. I was refunded it but still don’t know why I would need it. The website listed on the warranty card does not work so contacted Alec but only got the AI assistant which had no clue on how to help me. Needed to talk to a real person to get it resolved. I would have expected things to go a little better when working with a company who has been around longer."
"The flow rate is amazing! And the taste is even better. Very satisfied with this system, I used it for the dogs, drinking, cooking, coffee and haven’t run low. The system is 100% worth every penny."
"It is awesome, we had elevated uranium levels in our well water and we just had it retested after install and it came back with ND (none detected). Highly recommend"
"Works great! A pleasure to have RO water so accessible."
"This is my second APEC water filter system I have purchased in the last 15 years. The first one ran great for many years. When the flow slowed, APEC support was awsome to help me get it working again. I just purchased the Hi-Flow model and it is amazing. It was easy to replace the old model and it seems like twice the flow of my original. Definitely would recommend!"
"Best product ever. Good quality that produce excellent water"
"I purchase this system for every home I move to!"
