Staying hydrated keeps your brain sharp and your legs moving so you can hike out to safety days before a parasite could ever make you sick.

Why can't you use a Sawyer or Katadyn hollow-fiber water filter after it freezes?¶

Hollow-fiber membrane filters contain thousands of microscopic straw-like polymer tubes whose walls are perforated with 0.1-micron pores that physically block bacteria and protozoa. When wet water trapped inside those microscopic pores freezes into ice, it expands by 9 percent in volume and stretches or splits the microscopic pore walls open from the inside. Because the internal fibers are sealed inside an opaque plastic housing, the filter looks completely normal on the outside and still flows smoothly, but the enlarged tears allow microscopic Giardia cysts, Cryptosporidium oocysts, and E. coli bacteria to pass right through into your drinking bottle.

How long do you really need to boil water in the mountains to make it safe to drink?¶

According to the US Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and the Wilderness Medical Society (WMS), bringing water to a vigorous rolling boil for 1 full minute (or 3 minutes at high elevations above 2,000 meters / 6,560 feet) kills 100 percent of all waterborne human pathogens, including Cryptosporidium, Giardia, bacteria, and viruses. Even though water boils at a lower temperature at high altitude (for example, 89 degrees Celsius / 192 degrees Fahrenheit at 3,350 meters / 11,000 feet), all waterborne pathogens are rapidly inactivated once water temperature exceeds 70 to 85 degrees Celsius (158 to 185 degrees Fahrenheit).

Does household bleach or first-aid kit iodine kill Cryptosporidium in backcountry water?¶

No. While unscented household chlorine bleach (2 to 4 drops per liter for 30 to 60 minutes) and 10% povidone-iodine or 2% tincture of iodine (5 to 16 drops per liter for 30 to 60 minutes) are highly effective against bacteria, viruses, and moderately effective against Giardia cysts, neither bleach nor iodine can penetrate the thick, triple-layered outer shell of Cryptosporidium parvum oocysts. To kill Cryptosporidium without a filter, you must either boil the water, use Chlorine Dioxide tablets/drops (Aquamira or Katadyn Micropur MP1) with a full 4-hour contact wait time, or use UV light (SteriPEN or 6-hour clear-bottle solar SODIS).
