Yes you can. B2 Mask does not contain an exhalation valve or air vents. All exhaled air is filtered.
B2 Mask complies with guidelines set by airlines and governments concerning face coverings in enclosed public spaces. It protects both the wearer and their environment in several ways:
- All inhaled and exhaled air is filtered through B2 Filters, which remove >99% of particles 0.1 micron and larger.
- Full seal around the mouth and nose.
- No exhalation valve.
- No vents.
The images below show how circular B2 Filters are installed in the facepiece, which seals around the mouth and nose. The filters are the only path for air to go in or out of the mask, providing superior protection to cloth face masks.
