My 2 Cents: For all of you that live in second / third world countries where there is a risk of drinking tainted water this product my be for you. The price is a little steep but it does what it is supposed to then it should be worth it. This item might be a little overkill for some of you but better be safe than sorry…
Remember the LifeStraw, a sip-and-survive filtration straw? Here’s another solution for dealing with Gaia’s water woes: The Lifesaver bottle. Michael Pritchard developed the device after witnessing the devastation of Hurricane Katrina, apparently pouring his life savings into researching a chemical-free solution that’s able to purify 4,000 to 6,000 liters on a single filter. We’re not clear if this will work on sea water, but it will elimiate bacteria, viruses, parasites, fungi, and all sorts of 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
