Apparently your writers are complete retards.
Alcohol is produced by yeast and yeast alone.
Vodka is distilled from a simple sugar mash and collected as a neutral spirit at ~95% (190 proof) and is then diluted to achieve its commercial proof - typically 40% (80 proof).
Charcoal filtering improves flavor by absorbing fusil oils and other cogners. That's it.
If charcoal filtering increased alcohol content, then you could run beer through a brita and make whiskey.
Can you do that? No?
Then maybe Deirdre should quit sucking down Belvedere vodka and log-off for long enough to do just a wee bit of research before she posts inane bullshit on your blog.
