How Does PUR Work?
PUR removes bacteria, viruses, parasites, as well as dirt and
other sediments in only 30 minutes. Most low-cost water purification
methods do not remove all three classes of pathogens: bacteria,
viruses, and parasites. For example, most ceramic filters do
not effectively remove viruses. Most disinfectants, such as chlorine
or iodine-based disinfectants, may remove bacteria and viruses
but only removes parasites with a long waiting time. However
PUR is very effective in removing bacteria (99.99999% removal),
viruses (99.99%) and parasitic cysts like Giardia and Cryptosporidium
(99.9%). PUR also removes arsenic and DDT.
PUR is an easy-to-use product and there are only
three steps.
1. Introduce a 4g sachet of PUR into 10 liters (2.5 gallons) of
contaminated source water.
2. Stir well for 5 minutes and let the flocculent settle for
an additional 5 minutes.
3. Use a thick, 100% cotton cloth without holes to filter the
water.
After 20 minutes, your water is ready to drink or store.
