Water Treatment Drops

Aquamira is a two-part chlorine dioxide water treatment: mix drops from bottles A and B, wait five minutes for activation, then add to your water. Gear-heads carry it as an ultralight primary treatment or as a filter backup because chlorine dioxide handles viruses and bacteria without iodine's taste or discoloration.
