The filter must be changed regularly for the machine to function properly. When the filter icon continually appears on the navigation screen, you must replace the filter before using your Wellbox® again. Warning: Never use Wellbox® without a filter. Impurities sucked into it can seriously damage your Wellbox®. If you have any questions please call us at (701)223-9936 or Toll Free (800)355-2956
