For long-term storage, we recommend doing a thorough cleaning of the filter, caps and the soft bottle (this prevents mold from forming):

  • Dissolve 1 tsp of chlorine solution (common bleach) into a container filled with about 1-liter clean water. Remove the carbon capsule and dip the filter, caps and the soft bottle in the container and cover it well. Shake the mix and leave it for a night. 
  • Make sure to rinse the filter thoroughly after this procedure to remove all chlorine residue.
  • Dry all components and store.

After long time storage, fill the soft bottle with water, screw the filter on completely and allow to sit for a few seconds to prime the filter. 

The Flex is now ready to use once more.
