Missouri S&T researchers recommend combination of filters for homemade masks, other PPE
A team of researchers at Missouri University of Science and Technology found that several layers of household air filters can achieve filtration performance similar to masks rated N95 – masks that capture 95% of particles. The researchers studied the filtration performance of non-medical materials and recommend making homemade face masks with a combination of fibrous and fabric materials. They say the materials will sufficiently remove aerosols and avoid the inhalation of fiber fragments generated during the cutting and folding of the filters.
