How often should a mask be changed to most effectively fight COVID-19?

Since the beginning of the pandemic, masks have been identified as one of the most effective and essential measures to prevent the spread of the virus. This article will answer many questions regarding this wonderful means of protection.

What is the difference between N95, KN95, KF94 masks, surgical masks and cloth masks?

The main difference between these masks is the level of protection. N95 can filter out at least 95% of airborne particles and has been approved by the National Institute of Occupational Safety and Health (NIOSH). The KN95 type respirator has the same protection as the N95 but has been manufactured internationally. Surgical masks can block 42% to 51% of airborne particles. Cloth masks can block from 3% to 43% depending on the material and number of layers.

What type of mask should I choose?

Choosing a mask should be based on your comfort, the level of risk of the environment and the activity you are doing.

How often should a mask be changed?

Masks can be used for quite a long time, especially in the case of frequent use. However, you should not use them for longer than 1 day, which means you should change the mask every day. Besides, it should be noted that you should not touch the mask with your hands to avoid contact with dust particles in the air.

Can masks be washed?

Water can damage N95, KN95, KF94 masks and surgical masks. Cloth masks can be washed with regular laundry detergent. It is important to note that the cloth mask must be completely dried before reuse.
