Entering the third year of the COVID-19 pandemic, the latest nationwide surge in infectious diseases presents many challenges.

One of them is for the continuous and proper supply of masks, including the N95 breathing mask, which is often used in healthcare and other settings.

In a new study at Stony Brook University, researchers discover that N95 can be disinfected and reused using readily available methods using a dry oven in environments where new masks may not be available. did.

To address the shortage of N95 masks during a pandemic, many institutions were forced to look for other alternatives to protect healthcare providers and their patients.

In the study, the team found that treatment of N95 face masks with dry heat was sufficient to inactivate COVID-19 and these masks filter aerosolized particles for potentially exposed workers. Showed to maintain the ability of.

Researchers used dry heat sterilization to disinfect masks because many medical facilities may have more access to heat than other decontamination methods.

In contrast, other disinfection methods, including treatment with hydrogen peroxide vapor, may be equally effective in specially equipped facilities, but are usually not available in most hospitals and outpatient clinical care facilities.

The team also tested the autoclave, which is widely available in most hospitals and is a proven method of sterilization, but found that it failed to fit the respiratory system to the user’s face.

Therefore, researchers have ruled out autoclaves as a safe way to decontaminate N95 masks.

The team emphasized the importance of both optimal disinfection and mask conformance in the findings, and if other decontamination alternatives are not available, N95 masks after dry heat treatment to ensure the safety of health care workers. It suggests that it can be reused.
