Drop-ins come in the form of drops, tablets, and powders which are added to the water. They are made up of minerals in liquids, powders, and compressed tablets. When dropped into water they raise the pH and create a mild negative charge. Many people like drop-ins because they are small and quite portable. There is, however, some debate about how much of these products a person should use each day. Plus, they only add to the water and don't work as filtration devices in any way. In order to use drop-ins, you must first start with water that has already been filtered. They make a good choice if you're only going on a short trip, but for long term use there are better alternatives.
