The Purisoo portable water purifier will purify as much as 1,000 liters (2,000 bottles of water), filtering out 99.9% of bacteria and sediments. One filter cartridge replaces the equivalent of 500 1/2 liter plastic water bottles making this a green way to drink clean water. Fill the 400cc water tank in under 1 minute with clean drinkable water. It also reduces odors and cuts out viruses, even removing rust and urine, all using a manual pump to extract out purified water.
