The advanced filtration system removes the majority of contaminants from the water that can cause birth defects, cancer, fatigue, headaches, and other health problems.

Better For The Environment Than Water Bottles

Water bottles are an inexpensive and unsustainable solution to clean water. Most water bottles, 80% at least, end up in landfills, or even worse, in the ocean. Reducing plastic consumption is essential to ensuring the health of the world for generations to come.
