2 How to Disinfect Masks in the Microwave
First, use disinfectant solutions such as 0.9% saline solution or diluted 90-degree alcohol to spray on the mask. This step aims to moisten and disinfect the outer surface of the mask.
Spray the disinfectant on the mask
Place the mask in the microwave oven with the surface sprayed with disinfectant facing up. Set the microwave to microwave mode, and do not turn on the grill function. Use a microwave oven with a power of 800W for effective disinfection.
Run the microwave for 1 minute. The microwave energy will penetrate the layers of the mask and kill bacteria and viruses.
Note: During the microwave operation, it is recommended to keep a close eye on the process to detect any abnormalities and prevent potential fire hazards.
Disinfecting the mask in the microwave
After 1 minute in the microwave, take the mask out and wait for it to cool down before wearing it as usual. At this point, your mask is ready for reuse.
Research shows that up to 99% of bacteria and viruses on the antimicrobial mask are eliminated using this method.
