Lifestraw Personal Water Filter is a new invention by Switzerland-based Vestergaard Frandsen Group. It’s a compact water filter, which, according to the manufacturer, eliminates at least 99.9% of waterborne bacteria and protozoan parasites.
This product is very useful and practical, not only for backpackers, hikers, hunters, adventurers and travellers, but also in emergency situations.
Water is filtered through small tubes, hollow-fiber membranes.Those membranes contain small pores, which prevent bacteria and other pollutants larger than 0.2 microns from passing through. Lifestraw is designed to filter up to 264 gallons (1,000 liters), after which the pores will eventually clog and the water flow will be disabled.
Apart from its practicality and compactness, the great advantage of this water purifier, among others, is the ease of use. It allows you to drink water directly from streams and puddles, and you don’t have to wait for water to be filtered, because it happens immediately. When used for the first time, Lifestraw’s membrane has to remain in the water for 30 seconds, before you start drinking. The water will start flowing after 3-5 seconds.
Lifestraw has no batteries or replaceable parts; it doesn’t contain any chemicals or additives, so it will not leave the after-taste that is usually common with water purifiers. It can be used periodically, and in such a way it can last for up to 5 years, or 1 year if used actively.
The Lifestraw’s effectiveness was tested at the University of North Carolina, and it has been proven that it will prevent bacteria, such as Escherichia coli B and Enterococcus faecalis, the MS2 coli phage virus, iodine and silver to damage the health of the person who drinks the contaminated water. However, Lifestraw will not filter parasites like cryptosporidium of giardia, and heavy metals, such as fluoride or iron.
Lifestraw was launched in 2005 and it has won many prestigious awards. Filters have been sent to Pakistan, Africa, South America and Haiti, for disaster aid, while in North America it has been available from 2011. watch video below
