Shelf life: Stored under proper conditions, an unopened Purifier Cartridge has a shelf life of 10 years. After a cartridge has been used, it lasts at least three additional years.
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.
