US Patent 11771930 Hybrid face mask assembly

A hybrid disposable face mask has a first mask section having a filter area sized and shaped to fit in overlapping relationship only about the mouth area of the wearer and a second mask section having inserts, one for each nostril, sized and shaped to be sealably retained air tight in each nostril. The second mask section can be linked to a valve assembly which opens during exhale and closes during inhale. The first mask section may be supported solely by the second mask section or by separate structure. The combination allows one to eat and drink while breathing through the nose filter.
