 Katadyn Micropur MP1 Purification Tablets By: Katadyn Average Rating: 3.5 Total Reviews: 3 More Information Great product  On: 2008-09-05Perfect for any survival kit. 20 count should give you enough treated water for 5 days. The packaging is heavy duty so you dont have to worry about breaking the package while packing it in your kit. Must have for any survival situation in which you only have the bare minimums. Effective, doesn't make water taste too bad On: 2007-09-30Ive used these several times over the past year, and compared to other chemical water treatments theyre relatively painless. You dont 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. devil in the details  On: 2007-08-13No one has mentioned that one must treat the water for four hours to get the sterility touted. Thats a long time to wait for a drink! Lightweight and effective...  On: 2007-04-06One has to weigh the advantages and disadvantages of this product based on ones needs or requirements. IMO, the pros and cons are... Pros: These tabs weigh only a few ounces, but can treat up to 20 liters. They are very effective at killing off viruses, bacteria, Giardia, and Cryptosporidium(EPA accepted). This product is great if you cant build a fire or boil water. Cons: One tab for one liter so unless you stock up, you can only support one person for 5 days if you use 1 gal. or 4 liters per day for roughly $10. Compare this to 96oz(~56000 drops) of Clorox for $4 and it only takes 16 drops to treat 1gal. of water. Katadyn claims that their tabs leave virtually no taste to the water, but I disagree. There is a very strange taste in the water that is less tolerable than chlorine IMO. Minimum treatment time is 30 minutes for both. Alternative: Boil water for 5 minutes at any desired quantity at virtually no cost! :) |
