Pure and simple.

Refill your Lékué to-go bottle with these activated charcoal filters made from 100% all-natural coconut shells. The filter removes substances that give your water those unpleasant musty and metallic flavors, all while conserving minerals like magnesium and calcium. Each one lasts 30 days, and since you’re getting a four-pack here, you can say hello to four months of fresh, clean-tasting H2O.
