White Claw’s New Vodka is “Triple Wave Filtered”?

When I was reading reports on alcohol industry news, I came across an article about the launch of White Claw’s new Vodka product. White Claw claims that the Vodka is “Triple Wave Filtered”, which is described in the article, “…filtered three times with water pressurized to 6,000 pounds per square foot to simulate the power exerted by 3- by 30-foot ocean waves, hence the Triple Wave branding.”

How does this kind of filtering work?
