In order to keep your water purification drops fresh and effective, keep both bottles in a cool, dark place with stable temperatures. 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.
If you are not intending to use all of your kit within a month's time, we recommend storing your bottles with the cap on, and the droppers kept to the side. You can gently rinse your droppers for longer term storage.
It is ideal to store each bottle without the droppers in-place where possible. The cap that is included on each bottle at the time of delivery ensures that the contents are not exposed to air.
