(More customer reviews)I did a one week kayak/camping trip through the Amazon rainforest and purchased the Lifesaver 4000 to supply all the drinking water for myself and the two friends who joined me on this trip. The filter performed as described on their website and I was more than happy with the quality of the water that it produced.
One thing to note is that the water won't necessarily be crystal clear - but it will be safe to drink. We were filtering 'black water' from the rainforest (ie water that is stained black due to decomposing leaf matter) and the filtered water was slightly cloudy - but only really noticeable when compared against a bottle of tap water. Taste-wise, it was fine. From what I have read, no portable water filter is capable of producing crystal clear water in these conditions so I don't count this as a negative against the Lifesaver bottle.
Pumping the water was easy and didn't require much effort. Five or six pumps and then you could sit back and watch whilst the water came out of the teat, then as the flow slowed, a few more pumps. By the time the bottle is 3/4 empty, I would have to refill it. You could let the last quarter trickle out, but it was quicker to top up the bottle again as the water flowed out quicker once you re-pressurised the bottle. I should point out that our guide commented that it was the 'best' water filter he had seen based on how little effort it took to get a steady stream of water pumping out the bottle. He said that the filters he saw other groups bring normally required constant pumping to took forever to fill a bottle.
After the kayak trip, my friends and I continued to travel throughout South America for the next 3 months where we used the bottle for all our drinking water (since we didn't trust the mains water). None of us got sick for the entire trip which I put down to the filter working effectively given other travel companions did. Admittedly not scientific proof, but good enough for me - and I would definitely take such a filter with me if I was visiting places like the countries in South America again.

Developed in response to natural disasters such as 2004's tsunami and Hurricane Katrina, and in response to the world's increasingly threatened supply of clean, drinkable water, the Lifesaver 4000 Ultra Filtration Water Bottle is a simple-to-use, chemical-free water purification system that removes water-borne pathogens and reduces chemical residues from the water making it safe to drink anywhere. The world's first all-in-one ultra filtration water bottle, the Lifesaver Bottle makes easy-to-use, portable water filtration a reality for travelers and outdoors people everywhere.
The Lifesaver bottle eliminates the need for iodine tablets, tedious boiling, chemicals, tubes, shaking, scrubbing, waiting, and effort from the water purification process. The bottle uses a long-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 has a unique feature, which shuts the filter off when the cartridge has expired so you can get the maximum life out of your filter without the risk of drinking contaminated water.
The Lifesaver Bottle filters out all water-borne pathogens using a filter with holes 15 nanometers across to prevent even the smallest viruses, 25 nanometers across, to cross the filter, eliminating the need for chemicals to treat the water. The Lifesaver Bottle is fitted with a 4000UF replaceable purification cartridge that removes bacteria, viruses, cysts, parasites, fungi, and all other microbiological water-borne pathogens from your water.
The Lifesaver bottle also comes with an activated carbon filter made of a high specification activated carbon block, which reduces a broad spectrum of chemical residues including: pesticides, endocrine disrupting compounds, medical residues, and heavy metals such as lead and copper. The Carbon filter also eliminates bad tastes and odors from contaminates such as chlorine and sulphur. The carbon filter is designed to last for approximately 250 liters.
In addition to the purification cartridge and carbon filter, the Lifesaver Bottle is supplied with a pre-filter disc. The pre-filter disc protects the membranes of the purification cartridge from objects such as gravel, 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 those hard to reach areas like cracks in rocks or shallow puddles.
Exceptionally easy to use, the Lifesaver Bottle filters water on demand at the time of collection. Simply unscrew the base, dip the bottle in the nearest water source, 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 clean water can be drank immediately, directly from the Lifesaver bottle or poured into a separate container for storage. Designed to work at any angle and in any axis, not only are you able to drink from the bottle in any position, but you can also fill mugs, water bottles, pans, and other water storage vessels from any position.
The Lifesaver Bottle utilizes failsafe technology to protect you from drinking contaminated water toward the end of the filter cartridge's life. As the cartridge approaches the end of its life, the bottle requires a greater number of pumps to induce water to flow. When no more water can be induced to flow despite continuous pumping, the cartridge has expired and 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 will cause the flip lid to bulge. If pumping continues, then the teat will open and release the water and the pressure.
Due to its unique pneumatic action, the Lifesaver Bottle can be used to direct a jet of sanitized water directly onto a wound, cleaning away any other contaminants, allowing for levels of wound irrigation never before possible in the field.
Winner of the "Best Technological Development for Future Soldier System Enhancement" at Soldier Technology 2007, the Lifesaver bottle has earned the trust of the armed forces in delivering safe water anywhere in the world. Tested and approved for use by the United States EPA, the UK Water Compliance Guidelines, and the European Drinking Water Directive Council, the Lifesaver 4000 Ultra Filtration Water Bottle is a portable water purification system that you can rely on.
