This filter has been in my vacuum for over a year now. With each use I remove dirt and blow dust out of the filter. When using in a humid environment or occasionally super cleaning, I rinse the filter with warm water and dry it with a hair dryer. I also leave it in the sun so there isn't any moisture left behind which can turn into mold. I work in the mold business so it is important that all my filters are fresh and clean. What also makes this filter great is that it is a HEPA filter. The cost of one of these reusable filters is so small compared to using it.
