Active technology: Electroadsorption, ultra-powdered activated carbon and silver treated zeolites. Unlike standard mechanical filtration, the Ultralight Purifier Bottle is powered by a patented electroadsorptive media capable of removing submicron pathogens and inorganic contaminants. With [ONE PRESS], electroadhesion and ion exchange create a powerful submicron trap for pathogens (viruses, bacteria and protozoan cysts). Additionally, the purifier media contains many embedded layers of ultra-powdered activated carbon which create a large surface area for removing toxins like chemicals and heavy metals. Silver treated zeolites, a natural antimicrobial, inhibit growth and keeps the purifier fresh between uses.

Founded in 2012, GRAYL was inspired by two global travelers, Nancie Weston and Travis Merrigan, and their concerns about global plastic pollution and the poor quality (health, taste, odor, clarity) of water that people around the world endure daily. Nancie and Travis are committed to changing the status quo by making practical and durable filtration and purification solutions.
