Generally obtainable family materials had between a fifty eight% and 94% filtration rate for 1-μm micro organism particles, whereas surgical masks filtered ninety six% of those particles . A tea cloth mask was found to filter 60% of particles between 0.02 μm and 1 μm, where surgical masks filtered 75% . Simulation research generally use a 30 L/min or larger problem aerosol, which is round about 3 to 6 instances the air flow of a human at rest or doing mild work .
