title_body: After cleaning a bean to cup machine can I reinsert the same filter?
upvoted_answer: I don't know the machine you're using but it seems like the water filters have a lifetime counted in water litters so you don't have to change it everytime , just when it filtered the amount of water it's designed to.
  
  I think you should try at least once to tell the machine you're removing the filter to see if it remembers how old the filter is but you should probably wait to be near to your filter end to do so because if it doesn't remember how old it is you can just change it for a new one. But you should try to tell the machine , you'd rather loose a filter than bug your machine !
