Are B2 filters reusable?

Depending on what you use your B2 Mask for, the filters may be good for multiple uses.

Depending on what you use your B2 Mask for, the filters may be good for multiple uses. For example, if you only use it for short trips to the supermarket or other occasions where physical distancing is possible, your filters will last up to one month. However if you use it for a day-long shift in a workplace with frequent contact with the public, you should probably change the filters daily. See the article "When should I change my B2 Filters?" to better understand what is right for you. 

While B2 filters can be temporarily removed in order to clean the facepiece, they are not meant to be cleaned and reused themselves. If they are ever temporarily removed from the facepiece, please do so with clean hands and place them somewhere clean.
