Product Description

The Water Pasteurization Indicator (WAPI) is a simple thermometer that indicates when water has reached pasteurization temperature and is safe to drink.

Be prepared in an emergency! This water pasteurization indicator (WAPI) tells you when your water is safe to drink. Suspend the WAPI, wax end up, in a container of water and place in a solar oven or camp stove. The wax inside melts at water pasteurization temperature (149 F). When the wax has melted down to the bottom of the tube, the water is safe to drink. Flip it over and reuse again and again. Ideal for campfires, stove tops, solar ovens, and other methods too!

  • Pasteurize Water & Other Liquids
  • Perfect for Camping, Hiking, Backpacking, Hunting, Fishing, Boating, Camping
  • Bug-Out Bag
  • Essential for an Emergency Kit
  • Reusable
A single unit included. Keep it in your car or in your emergency kit.
