This water purifier can supply a family of five for three years, providing 4,750 gallons of clean drinking water. It's lightweight (1.6 lbs.), portable and has a flow-rate of 9 - 12 qts. per hour. It filters to 0.02 microns, removing a minimum of 99.99% of viruses, bacteria and cysts. The unit requires no electrical power, batteries or replacement parts and it has an easily cleaned pre-filter and purification cartridge. It is perfect for home use and for base camping and vehicle camping.

Here's how it works: Using its 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, viruses, protozoa and other contaminants are trapped inside the hollow fibers and are flushed out by backwashing.

  • The feed water bucket (2 qt. capacity) is filled with water.
  • The 80-micron textile pre-filter (inside the feed water bucket) removes coarser particles and is easy to clean.
  • Water passes through the meter-long blue PVC hose and gravity creates sufficient pressure on the membrane cartridge in order to reach a high flow rate.
  • Ultra filtration takes place in the hollow fiber membrane cartridge - a pore size of 20 nanometers (0.02 microns) retains bacteria, viruses, parasites and fine dirt particles.
  • The blue tap is turned to release purified water.
  • You then backwash the membrane by squeezing the red backwash bulb 3 times with both taps closed and then releasing the dirty water from the red tap. Water from the red tap should never be consumed.
