These easy to use Shake Filters work like tea bags, and they'll guarantee you some clean tasting water no matter where you fill up.

Created by Vapur, the company behind collapsible water bottles, you'll just need to drop them in a bottle of water and thoroughly shake them to remove chlorine and other particles that will affect the smell and taste. Make your water taste like Evian anytime, anywhere!
