Speaking at TED in 2009, Pritchard estimated that by using the LifeSaver bottle, reaching the Millennium Development Goals of halving the number of people without drinking water will cost $8&nbsp;billion; while $20&nbsp;billion would provide drinking water for everyone on Earth.<ref name=TED>{{cite web |first= Michael|last= Pritchard|title= Michael Pritchard's water filter turns filthy water drinkable|url= https://www.ted.com/talks/michael_pritchard_how_to_make_filthy_water_drinkable|publisher= TED |date= August 2009|access-date=13 September 2009}}</ref>

=== Independent test results ===

In 2007, the LifeSaver bottle was tested by the London School of Hygiene & Tropical Medicine and the results found it to completely filter out all bacteria and viruses.<ref>[http://www.lifesaversystems.com/documents/LSHTM.pdf - London School of Hygiene & Tropical Medicine], lifesaversystems.com {{Webarchive|url=https://web.archive.org/web/20111119231433/http://www.lifesaversystems.com/documents/LSHTM.pdf |date=2011-11-19 }}</ref>

==Use== The bottle's interchangeable filter can purify between 4,000 and 6,000&nbsp;litres (1,050 to 1,585&nbsp;gallons) before it stops working and needs to be replaced.<ref name=Real/> It filters out objects bigger than 15&nbsp;Nanometres—including viruses, bacteria, and cysts.<ref name=Drinkable/><ref name=Purifies/> The carbon filter does not require chemicals.<ref name=Purifies/> The process of filtering the water takes 20&nbsp;seconds, allowing for 0.71&nbsp;litres (1.5&nbsp;pints) of water to be filtered.<ref name=Purifies/> Once a filter has reached its limit, it will not allow contaminated water to be drunk.<ref name=Purifies/> The LiveSaver bottle has been used by soldiers for drinking water as well as cleaning wounds.<ref name=Real/><ref name=Drinkable/><ref name=Purifies/>

To filter the water, one puts contaminated water in the back of the bottle, then screws the lid on. The lid has a built in pump which is operated manually with a hand; the pumping action forces the contaminated water through the nano-filter and safe drinking water collects in another chamber in the bottle. The drinker then opens the top of the bottle from which safe drinking water comes out.{{Citation needed|date=February 2026}}

A much larger version of the LifeSaver bottle, called the LifeSaver Jerrycan, has the same filtering technology. The can allows for the filtration of 10,000 to 20,000&nbsp;litres (2,650 to 5,300&nbsp;gallons).<ref>{{cite web|title= The LifeSaver jerrycan: Performance and technical data|url= http://www.lifesaversystems.com/jerrytech.html|publisher= Lifesaver Systems|accessdate= 13 September 2009|archive-url= https://web.archive.org/web/20090914035209/http://www.lifesaversystems.com/jerrytech.html|archive-date= 2009-09-14|url-status= dead}}</ref> One jerrycan filter can provide water for four people over a three-year span.<ref name=TED/>

== Limits == The bottle can be used to filter urine and will remove all microbiological contamination. However, there will be an amount of dissolved salts that can not be removed. Metals such as iron, and salt from salt water cannot be removed effectively, either.<ref>[http://www.lifesaversystems.com/FAQRetrieve.aspx?ID=35074&Q= LifeSaver bottle Questions and Answers], lifesaversystems.com {{Webarchive|url=https://web.archive.org/web/20111104031455/http://www.lifesaversystems.com/FAQRetrieve.aspx?ID=35074&Q= |date=2011-11-04 }}</ref>
