4. IS THE SOTR NIOSH APPROVED? 
While SOTR is not NIOSH approved, it is tested to the same high standards. SOTR meets the NIOSH requirements for inhalation and exhalation breathing resistance, P100 filtration, and exhaust valve leakage specifications for half mask particulate respirator. 
5. WILL SOTR PROTECT AGAINST COVID-19 (CORONAVIRUS)? 
CDC recommends wearing cloth face coverings in public settings. They also indicate that N95 masks are effective in limiting the transmission of the COVID-19 virus. SOTR provides P100 level filtration – which is greater than N95. Since SOTR is a reusable mask, care must also be taken to clean and sanitize the mask between uses or possible exposures.
