Can You Disinfect a Surgical Mask to Wear Again?

Surgical or medical masks are intended for single-use purposes, which means they are designed to be discarded after a single use. However, in the face of a shortage of new supplies, some are seeking ways to reuse these masks. This article explores whether it is possible to disinfect a surgical mask for reuse, weighing the practicality and effectiveness of such a practice.

Understanding Surgical Masks

Surgical masks are often made of multiple layers, typically three ply, and are constructed of either woven or non-woven materials. The primary function of a surgical mask is to prevent the user from spreading droplets that could contain pathogens. They are designed to be discarded after a single use to maintain their efficacy and reduce the risk of contamination.

Disposable and Washable Masks: Disposable surgical masks are designed to be used once and then thrown away. On the other hand, washable cloth masks can be cleaned and reused, but this is not the case for disposable paper masks, which can crumble if exposed to moisture or cleaning agents.

Washing vs. Disinfecting Surgical Masks

Wearing a surgical mask more than once is not recommended due to its design and materials. If the mask is washable, it can be safely laundered and sanitized. However, if the mask is made of waterproof or paper materials, it should be discarded after a single use. Masks are inexpensive, but they cannot be made without compromising their protective properties.

Sanitization Methods for Surgical Masks

According to the CDC, there are specific methods to sanitize and reuse surgical masks. These methods include:

Room Temperature Drying: After use at home, carefully remove the mask by the ties and place it in a paper bag for three days to allow the mask to dry completely. This process can help reduce the risk of microbial growth. Storage: Store the dried mask in a clean, dry place for future use. It is recommended to use the mask for up to five sequential uses before discarding it.

It is also crucial to ensure that the mask is not worn out or damaged before reuse. Any wear and tear can compromise the mask's efficacy, making it less protective.

Company Recommendations and Supply Chain Issues

While it is possible to reuse surgical masks under certain conditions, it is essential to consult the product description or follow the manufacturer's recommendations. As companies address supply chain issues, masks are not currently in short supply, but it is always best to practice responsible use.

Mask Disinfection vs. Cleaning: Some people mistake spraying disinfectants or washing surgical masks as a viable disinfection method. However, this can damage the mask's integrity and reduce its effectiveness. Spraying with disinfectants or washing with water can cause the mask to break down, compromising its protective properties.

The Last Word

In conclusion, while it is possible to disinfect a surgical mask for reuse, it is important to do so carefully and with the proper methods. The CDC provides detailed guidelines on how to safely reuse masks, emphasizing that even when reused, a mask will never be as effective as it was when new. The best practice remains to use disposable masks as intended and to prioritize personal and public health through responsible mask use.
