What type of mask should be used to prevent bacteria?

To protect against pathogens, you can choose medical surgical masks, N95/KN95 masks, medical protective masks, children's medical masks, or daily protective masks. Appropriate masks should be selected based on different situations to effectively block bacteria in droplets and aerosols. If you have symptoms such as fever or cough and need to visit crowded places, it is recommended to prioritize high-protection-level masks and seek medical attention promptly.

1. Medical Surgical Masks: These masks can filter droplets and block certain bacteria. They feature a waterproof outer layer, a filtration middle layer, and a moisture-absorbing inner layer. Suitable for daily commuting, shopping, and other common scenarios, they meet the pathogen protection needs in most situations.

2. N95/KN95 Masks: With a filtration efficiency of over 95%, these masks effectively block pathogens in droplets and aerosols. They are suitable for use during hospital visits, when in contact with infected individuals, or in high-risk environments. Their protective performance exceeds that of standard medical surgical masks.

3. Medical Protective Masks: Meeting higher protection standards, these masks offer both strong filtration and tight sealing. They are designed for healthcare workers when treating patients with infectious diseases and are capable of handling high-concentration pathogen exposure. The general public may also use them under extreme risk conditions.

4. Children's Medical Masks: Designed according to children's facial features, these masks provide a better fit to prevent air leakage and ensure effective protection. Made from softer materials, they reduce skin irritation and meet children's needs for infection protection during daily activities or medical visits.

5. Daily Protective Masks: Suitable for low-risk settings such as walking near home, these masks can block dust and some droplets. Although their protection level is lower than medical-grade masks, they provide adequate basic protection in areas without significant outbreaks.

Masks should be replaced regularly in daily use; reuse should be avoided. When storing, fold the clean side inward and avoid touching the contaminated surface. Wash hands before wearing, dispose of the mask immediately after removal, and maintain cleanliness and hygiene to ensure optimal protection.
