As simple as water from the tap
The easy-to-use plastic design that characterizes the LifeStraw® Family simplifies on-site conversion of large quantities of dirty water into potable water in villages and by families. The primary element is an approximately 30 cm long plastic housing that contains filter membranes made from Ultrason E. They provide ultrafiltration (UF membranes) and remove viruses as well as bacteria from dirty surface water that may have come from rivers, lakes, rainwater collection barrels or puddles.
Ultrason resin for high precision filters
The unique benefit of the high-performance resin Ultrason E in such filters is that it lends itself extremely well to production of membranes with a precisely controlled pore size and thus exactly defined filter characteristics. By using the portable purification station, the risk of contracting gastrointestinal illnesses from dirty water is reduced drastically. According to information from the World Health Organization (WHO), 1.8 million people die yearly from diarrheal illnesses. More than one billion people worldwide do not have access to clean drinking water.
Fill up, filter, and drink
The LifeStraw® Family system is not only lightweight and easy-to-use, but also inexpensive. It is able to purify at least 18,000 litres of water reliably without the need for batteries, electricity, replacement parts, chemicals or complex technology. Water purified by the unit has been tested by the EPA and declared potable. The EPA (United States Environmental Protection Agency) is the agency within the American federal government responsible for enforcing environmental regulations. The products can be quickly and easily distributed during natural disasters. Vestergaard Frandsen worked in conjunction with non-governmental agencies to ship their products rapidly in response to Myanmar’s cyclone Nargis in May 2008 and the Chinese earthquake in August 2008.
