In order to keep your water purification drops fresh and effective, keep both bottles in a cool, dark place. Do not allow them sit in direct sunlight or near sources of heat.

Your kit is best-kept in a pantry or in the refrigerator.

For infrequent use, we recommend storing your bottles with the bottle cap securely fixed.

For longer term storage, it is best practice (most ideal) to store each bottle without the droppers in-place. The cap that is included on each bottle at the time of delivery ensures that the contents are not exposed to air.
