If this filter works then everything is fine. However, lately there have been a lot of filters in the pack that don't last longer than 2-3 weeks! They should last for 2 months! Today I opened up a fresh filter to inspect it closely and yes there is charcoal dust on the packaging but the filter was also wet and dripped onto my desk. I will consider buying a different brand of mug. Don't believe all the rave reviews.
