Water Pasteurization Indicatorwapi_case-1 (Duplicate)

Have you ever heard of a WAPI? It is a very simple, yet useful tool for emergency preparedness.

The WAPI (Water Pasteurization Indicator) is a specialized thermometer used to indicate when water has been heated to the pasteurization point and is safe to drink.

A WAPI has a temperature-sensitive wax in a transparent tube that melts and drops to the bottom at 150° F (65° C). Once that temperature has been maintained for five minutes or more, the water is then safe for consumption.

Simply plug the glass cylinder into the bottom hole in its case and float in the water container to be pasteurized.

Extensive research has shown that dangerous pathogens and microbes, such as E. coli, Rotaviruses, Giardia, etc., are killed when exposed to more than 150° F, and don’t need to be heated to boiling (212° F).
