The present disclosure relates to a composition that includes a base layer having an outer surface and a first thickness and a material that includes a plurality of cellulose nanofibers in physical contact with the outer surface, where the composition has an average filtration efficiency of less than or equal to 90% for particles having a characteristic length between about 50 nm and about 100 μm and the composition is characterized by an average inhalation resistance of less than or equal to 35 mm HO as measured across the first thickness and the material.

Cellulose-containing filtration materials and methods of making the same

Disclosed herein are a cellulose particle and a binder, where the cellulose particle has a cellulose core and a surface group, and the binder interacts with the surface group to form a composite.
