Maintenance replacements
I'm aways thoroughly confused by the multitude of part identification numbers, many of which reference the same (?) parts but use different part numbers. I dread ordering consumables and then determining where they go in the filtration system.

Easy filter maintenance
We just replaced our APEC RO filters on schedule. We appreciate that we receive easy to follow instructions each time we reorder filters. We need the reminder of the process. We also appreciate how quick and easy a job it is.

RO replacement filters
I have enjoyed my APEC RO system for over a year and recently replaced the stages 1-3 filters. Everything is working great and I am extremely happy with the quality of the system and the filtered water. I no longer worry about the forever chemicals and pharmaceuticals in my drinking water now which gives me peace of mind every time I pour a glass!!

Auto reorder is great
I signed up for auto reorder for filters about a year ago. It is great because I don’t have to keep track of when it’s time to replace my filters. When the new filters arrive, I just put them in.

Not A Good Experience
I have ordered many times from your website and then the last time I was set up for auto renewal without knowing it. The filters showed up and I was charged for them when I did not want them yet. The website is deceiving in that you have to uncheck a box to not be on auto renewal. You have a good product at a good price. You do not need to use these business practices to grow your business. I am disappointed that this happened and may choose another supplier for my filter elements.

Our water tastes SO much
Our water tastes SO much better. I continue to test just with a TDS meter. It continues to be 0. It was 325 without Apec. We love it!

Filter replacement
I live in Monterey, CA. When I gained access to the pre-filters, I was appalled at the dirty state of the sediment filter. I am very glad to have the APEC reverse osmosis system. I was so appalled that I took the filters to the CalAm water office to show them how dirty they were. They didn't take responsibility for the state of the water and blamed me for not changing the filters more often!

Great product
We love our APEC RO system. Changing filters is easy and we have great clean water! The autoship every 6 months means I don't have to remember to place an order.
