"I've been using this APEC water filter for the last 7 years and I love it. The water tastes really good. 👍"
"I am really, not sure how to review this product as I have not yet installed it. The reason I have not installed it yet is because when it arrived, it had such a strong odor that I had to leave it out in my garage. I opened the box, and that was it. For the last few weeks. It has sat in the box in the garage while I wait for the strong chemical odor to dissipate. So I am really, not sure what to do, as I’m not really comfortable in changing out the current filters for these. The chemical odor is disturbing."
"I love my APEC reverse osmosis setup. I’ve had it for several years now and have used only APEC filters to keep it going. Guests and extended family have commented on how good my water tastes. I like the extra crispness in my coffee taste and my wife calls herself a “water snob. ” Only odd thing… My manual and all the flyers included with parts I’ve ordered say “Replace filters 1-3…and 6 every six months. ” I buy the “Filters for a year” package and it has two of 1-3 and one 6. When I inquire as to why, I’m told “you can buy an additional #6 if you want. ” Makes no sense as the flyer in the package I just got still says #6 should change six months. I don’t get it. Is it really a “Year’s filters” or is Apec cheating out on me? BYW: I am very happy with my APEC and have told everyone it’s a good product."
"Service was great. I just ordered the wrong thing. Thought I was getting all six stages but got the year supply instead."
