A '''cloth face mask''' is a non-medical makeshift face mask. They have been used widely during the [[COVID-19]] pandemic by civilians. They have been shown in a randomized trial done in 2015 to filter only 3% of infectious material, compared to surgical masks which filtered 56%. Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection. While the CDC and WHO promotes them, the only possible way they would work requires [[social distancing]] to work.
