The results, reported in the journal BMJ Open, show that a lot of the materials generally used for non-clinical face masks are effective at filtering ultrafine particles. N95 masks have been extremely effective, although a reusable HEPA vacuum bag actually exceeded the N95 efficiency in some respects. A staff of researchers has examined every thing from t-shirts and socks to denims and vacuum luggage to find out what kind of mask material is most effective at trapping the ultrafine particles which will include viruses corresponding to SARS-CoV-2, the virus which causes COVID-19.
