3M Water Filtration System Info

[armullis59]

My 2016 Adventurer has a 3M water filtration system under the kitchen sink. It had an “A1” filter installed. Well, the A1 is no longer available. I emailed 3M and asked what replaced the A1 filter. The response was the “Aqua-Pure C-Cyst-FF Part # 5610428”.

That filter worked perfectly in place of the A1, even though the new filter was physically longer than the A1.

I too had to change to the new filter a couple of years ago.It was too long so I had to raise the filter mount and replumb one water line.

Thanks so much for the info. We have a 2015 Itasca Suncruiser with the same under sink filtration system. Purchased used and found no cartridge installed. I was about to contact 3M as Winnebago Parts and 2 dealers were of no help at all! What a relief to find the answer right after logging into this forum!
