What if you were in a crisis situation and you needed water but you couldn’t wait for it to boil? What if your fuel choices were limited? A great solution to keep in your survival kit is a water pasteurization indicator (WAPI) to help ensure that you will always have safe water to drink.
A Water Pasteurization Indicator (WAPI) is a simple thermometer that indicates when water has reached pasteurization temperature and is safe to drink. The WAPI can be used on a campfire, with charcoal, propane, or with any type of fuel.
The Multi-Fuel WAPI comes with a high-temperature molded polypropylene case which serves as a carrying case for storage and as a float to enable the WAPI to be submerged in the water. In use, the transparent tube is removed from the case and snapped into the hole provided in the bottom, with the wax end up. The case is placed in a pot, pan or jar that has been filled with water. When the wax has dropped to the bottom of the tube, the water is pasteurized and thus safe to drink.
The WAPI can be reused hundreds of times.
