Review title: Effective, doesn't make water taste too bad
Product review: I've used these several times over the past year, and compared to other chemical water treatments they're relatively painless. You don't have to force yourself to down chemical-tasting water.To the earlier reviewer who mentioned treatment time: 4 hours is a worst-case scenario mandated by the EPA for killing one type of organism (cryptosporidium) in water that is both very cold and very dirty. All bacteria and viruses, except cryptosporidium and giardia, are killed in 15 minutes (even in cold water). Cryptosporidium and giardia are both killed in 30. In cold, very dirty (cloudy) water, it can take 4 hours for a full crypto kill.
