For water purification tablets, well, let me quote Red Green: "The human kidneys are a remarkable filtration system."

The date of manufacture is stamped on the side of the iodine potable water tabs. The link below explains how to read it. They should be replaced every 4 years if unopened and stored in reasonable conditions.
