The US Center for Disease Control (CDC) cites the N95 respirator standard as part of the advised protective equipment in their Covid-19 FAQ and their SARS guidance (SARS being a similar type of Corona virus). Which suggests that an N95 or better respirator is acceptable.
The CDC also states the the KN95 Respirator is equivalent and approved to use as an alternative to N95 Respirators. 3M also stated that the KN95 Respirator is equiovalent to the N95 model. CDC Link here. 3M link here.
