Pocket handkerchief with improved hygiene, comprises two partially connected layers for filtering out virus-containing aerosols expelled during sneezing

摘要

A multilayer pocket handkerchief, with improved hygiene, is such that during sneezing (a) the nose is located between two partially connected handkerchief layers and (b) aerosol-containing expelled air flows between the layers and preferably (after utilizing the filtration effect to remove aerosols) escapes from openings provided at the side and bottom (rather than only upwards).
