Are marine Aquarium supplies safe???

[Cvoss]

So we're looking for a way to make our vodka more pure and neutral. I used to have a reef tank in my house so im very familiar with some of the things used in the hobby. Someone had told me that a good way to get your vodka more pure is to run it through an RO / DI system like this

Mostly for the carbon and the micron filters. i always get nervous using plastic with distilled spirits in fear of leeching... What do you guys think?

i also thought of using a reactor like this

To run the vodka through activated carbon....

Has anyone ever tried this? Is it safe? Suggestion?
