LifeStraw® Family 1.0

lifestrawfamilyteaserimageLifeStraw® Family 1.0 is a powerful, high-volume 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.

  • Converts microbiologically contaminated water into clean, safe drinking water
  • Filters up to 18,000 litres of EPA-quality water, enough to supply a family of five with clean drinking water for three years
  • Removes virtually all bacteria (99.9999 percent), protozoan parasites (99.99 percent) and viruses (99.999 percent) that can contaminate water
  • Reduces turbidity (muddiness) by filtering particulate matter larger than 0.02 microns
  • Made of durable plastic
  • Doesn’t require electrical power, batteries or replacement parts  
  • Uses hollow fibre technology which meets the standard for the “highly protective” category of safe water interventions by the World Health Organization

How It Works

    • 780 million people in the world lack access to an improved source for drinking water1.
      VF2011Carbon4Water 2083
    • 61 percent of people in sub-Saharan Africa still don’t have access to safe drinking water1.
    • Lack of access to safe drinking water contributes to the staggering burden of diarrheal disease worldwide.
    • Nearly one in five child deaths – about 1.5 million each year – is due to diarrhea1.
    • LifeStraw® also addresses cryptosporidium which was recently found to be a leading cause of diarrheal illness in children under five and is attributed to higher mortality in children under two4.
    • Point-of-use (POU) treatments such as LifeStraw® Family can accelerate the health gains associated with the provision of safe drinking water to at-risk populations. 
    • Improvement of drinking-water quality, such as point-of-use disinfection, could lead to a 45% reduction of diarrhea episodes2.
    • Among all point-of-use water treatment methods, water filters have been shown to be the most effective for reducing diarrheal diseases3.
    • LifeStraw® Family is the backbone of the LifeStraw® Carbon for Water™ campaign in Kenya, which is providing more than 4.5 million Kenyans with sustainable access to clean and safe drinking water.

    LifeStraw
    ® Family uses advanced hollow fiber technology. Water is forced through narrow fibers under high pressure. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, protozoa, and other contaminants are trapped inside the hollow fibres and are flushed out by backwashing. This is a highly efficient method of filtration.

    1. Feed water bucket with prefilter has 2 litre capacity for filling with unpurified water
    2. The 80 micron textile prefilter removes coarser particles and is easy to clean
    3. Halogen chamber releases low-level chlorine to prevent membrane fouling
    4. Plastic hose is one metre long. Gravity creates sufficient pressure on the membrane cartridge in order to reach a high flow rate
    5. Ultra filtration takes place in the membrane cartridge – a pore size of 20 nanometre retains bacteria, viruses, parasites and fine dirt particles
    6. Blue tap is turned to release purified water
    7. Backwashing of the membranes is done by squeezing the red bulb three times and releasing the dirty water from the red tap
    8. Exit valve disposes the dirt and impurities

    NOTE: Water from the red exit tap should never be consumed.
