The LIFESAVER 4000UF bottle is a microbiological waterfilter that uses ultra filtration technology to filter out viruses, bacteria,cysts and parasites from contaminated water sources to produce clean drinkingwater. LIFESAVER technology filters out bacteria to a minimum of Log 6(99.9999%), viruses to Log 4 (99.99%) and cysts to a minimum of Log 3 (99.9%)as specified by NSF Protocol 231, based on recommendations of the U.S.Environmental Protection Agency (EPA). This LIFESAVER bottle is a robust andportable water filter capable of delivering up to 4,000 liters / 1,056 USgallons of clean water for individual use. The LIFESAVER bottle holds up to750ml at any one time is designed to support individuals embarking oninternational travel, adventure challenges and expeditions where the qualityof the water supply is in question. The LIFESAVER bottle was designed to storeand carry dirty water, once water is cleaned there is risk of recontamination.With the bottle, just filter water when you want to drink it. No need formeasuring, waiting or unpleasant distaste from chemicals such as chlorine orchlorine dioxide. Used by expedition companies, explorers, adventurers andpeppers for producing clean water in the most unforgiving of environments -where clean water just can't be guaranteed. Developed in responseto natural disasters such as 2004's tsunami and Hurricane Katrina, and inresponse to the world's increasingly threatened supply of clean, drinkablewater, the Lifesaver 4000 Ultra Filtration Water Bottle is a simple-to-use,chemical-free water purification system that removes water-borne pathogens andreduces chemical residues from the water making it safe to drink anywhere. Theworld's first all-in-one ultra filtration water bottle, the Lifesaver Bottlemakes easy-to-use, portable water filtration a reality for travelers andoutdoors people everywhere. The Lifesaver bottle eliminates the need foriodine tablets, tedious boiling, chemicals, tubes, shaking, scrubbing,waiting, and effort from the water purification process. The bottle uses along-term use replaceable filter, which can treat about 4,000 liters of water,5.5 years of usage if you drank two liters of water every day. The bottle hasa unique feature, which shuts the filter off when the cartridge has expired soyou can get the maximum life out of your filter without the risk of drinkingcontaminated water. The Lifesaver Bottle filters out all water-borne pathogensusing a filter with holes 15 nanometers across to prevent even the smallestviruses, 25 nanometers across, to cross the filter, eliminating the need forchemicals to treat the water. The Lifesaver Bottle is fitted with a 4000UFreplaceable purification cartridge that removes bacteria, viruses, cysts,parasites, fungi, and all other microbiological water-borne pathogens fromyour water. The Lifesaver bottle also comes with an activated carbon filtermade of a high specification activated carbon block, which reduces a broadspectrum of chemical residues including: pesticides, endocrine disruptingcompounds, medical residues, and heavy metals such as lead and copper. TheCarbon filter also eliminates bad tastes and odors from contaminates such aschlorine and sulphur. The carbon filter is designed to last for approximately250 liters. In addition to the purification cartridge and carbon filter, theLifesaver Bottle is supplied with a pre-filter disc. The pre-filter discprotects the membranes of the purification cartridge from objects such asgravel, sand, sticks, and mud, prolonging the overall life of the cartridge.Your pre-filter disc may also be used as a sponge to soak up water from thosehard to reach areas like cracks in rocks or shallow puddles. Exceptionallyeasy to use, the Lifesaver Bottle filters water on demand at the time ofcollection. Simply unscrew the base, dip the bottle in the nearest watersource, and pump the water through the filter to a teat at the other end,purifying up to 750 milliliters of water in just under a minute. The cleanwater can be drank immediately, directly from the Lifesaver bottle or pouredinto a separate container for storage. Designed to work at any angle and inany axis, not only are you able to drink from the bottle in any position, butyou can also fill mugs, water bottles, pans, and other water storage vesselsfrom any position. The Lifesaver Bottle utilizes failsafe technology toprotect you from drinking contaminated water toward the end of the filtercartridge's life. As the cartridge approaches the end of its life, the bottlerequires a greater number of pumps to induce water to flow. When no more watercan be induced to flow despite continuous pumping, the cartridge has expiredand it is time to replace it. The Lifesaver Bottle is designed not to over-pressurize as a safety feature to prevent injury. Over-pumping the bottle willcause the flip lid to bulge. If pumping continues, then the teat will open andrelease the water and the pressure. Due to its unique pneumatic action, theLifesaver Bottle can be used to direct a jet of sanitized water directly ontoa wound, cleaning away any other contaminants, allowing for levels of woundirrigation never before possible in the field. Winner of the "BestTechnological Development for Future Soldier System Enhancement" at SoldierTechnology 2007, the Lifesaver bottle has earned the trust of the armed forcesin delivering safe water anywhere in the world. Tested and approved for use bythe United States EPA, the UK Water Compliance Guidelines, and the EuropeanDrinking Water Directive Council, the Lifesaver 4000 Ultra Filtration WaterBottle is a portable water purification system that you can rely on.
