Efficacy of treatment in a rice cooker-steamer including 8-10 minutes of heating and 5 minutes of steam vs dry heat at 100°C for 15 minutes in an oven for decontamination of methicillin-resistant Staphylococcus aureus (MRSA) and bacteriophage MS2 on 3M 1860 N95 respirators, surgical face masks, and cotton and quilting fabric cloth face masks. 10-μL aliquots containing 106 colony-forming units (CFU) or plaque-forming units (PFU) of the test organisms in the simulated mucus suspension were spread to cover an area of 1-cm on inner and outer surfaces of the N95 respirators and surgical face masks and on 1 surface of the cloth masks.
