Culligan Water

This weekend at a fishing tourney I won a Culligan Preferred Series 350 water system during a raffle.
Just wondering if anyone knows off hand if its 'cleansed' water is safe enough for top offs?
Thanks.

I don't think so. It appears to just be a large 0.5 micron carbon block filter. It's just one, of the 5 stages of filtration you typically get on a RO/DI system.
