LifeStraw Family 1.0
[LifeStraw® Family 1.0] (http://www.vestergaard.com/lifestraw-family-1-0 “http://www.vestergaard.com/lifestraw-family-1-0”) is a high-volume, point-of-use water purifier for use in homes without access to clean water from municipal sources. It helps prevent often deadly waterborne diseases for families in developing countries and is effective in emergency settings following natural disasters which can contaminate water

Performance & use
LifeStraw Family achieves ultrafiltration via hollow fiber technology whereby water is forced through narrow fibers under high pressure.
When untreated water is poured into the feed water bucket, the textile prefilter removes coarse particles larger than 80µm. Gravity pushes the water with particles finer than 80µm to flow down the plastic hose towards the purification cartridge. The purification cartridge, which contains a hollow-fibre membrane of 20nm porosity, stops all particles larger
than 20nm but bacteria, protozoa, and other contaminants are trapped inside the hollow fibers and are flushed out by [backwashing.] (http://www.clubrunner.ca/Data/6970/2143/html/111458/e-brochure-lifestraw-and-lifestraw-family-english.pdf#page=9 “http://www.clubrunner.ca/Data/6970/2143/html/111458/e-brochure-lifestraw-and-lifestraw-family-english.pdf#page=9”)

Lifestraw Family units are monitored by trained community representatives employed by Vastergaard. Lifestraw users must be trained on the operation and maintenance of the units. Representatives conduct visits to homes to analyze and report on units that are not operating normally ^Interview ^with ^representative
Replacement systems are available if community representatives determine that the unit is faulty. All units are tracked via QR codes by representatives ^Interview ^with ^representative
Guaranteed up to 18,000 Liters (4,750 Gallons). According to Vastergaard, enough to supply clean drinking water for a family of five for up to [3 years] (http://www.clubrunner.ca/Data/6970/2143/html/111458/e-brochure-lifestraw-and-lifestraw-family-english.pdf#page=12 “http://www.clubrunner.ca/Data/6970/2143/html/111458/e-brochure-lifestraw-and-lifestraw-family-english.pdf#page=12”)

Contamination of filtered water is possible with exposed/improper handling and storage.
The improved performance of this model has been addressed by the new and improved LifeStraw Family 2.0, which is now being released to the market.
