The LifeSaver is a water filtration device that uses various filters to screen out even the smallest viruses as well as bacteria, contaminants, and pathogens. Available in several different sizes to suit personal, family, travel, and emergency disaster use, these filters can clean 750ml of water in less than a minute, transforming polluted water into life-saving hydration. Although they were quite expensive when first developed, they have dropped in price to be much more affordable, and have been put to great use in communities all over the world.
