Cool inventions like the Lifesaver water filtration water bottle are making water purification easier. Remember the water purification bike… not so easy. The lifesaver bottle by Michael Pritchard will purify 4,000 to 6,000 liters on a single (replaceable) filter. The filter will eliminate bacteria, viruses, parasites, fungi, and other microbiological waterborne pathogens.
“The invention, which won an award from Well-Tech, has a replaceable filter that’s good for 5.5 years, based on 2 liters a day. Filtering 750ml of water takes just under 1 minute, and once the cartridge expires, the unit will shut itself off. But before it can be truly effective for the masses in developing nations, something will need to be done about its $460 price.”
