1. Different certifications: N95 masks are one of the nine types of particle protective masks certified by the National Institute for Occupational Safety and Health. The anti-particulate mask products sold by 3M in China originate from different origins. In addition to obtaining the certification required by the place of origin, they have also obtained China Labor Safety (LA) certification.

2. Different effects: 95 means that when exposed to a specified number of special test particles, the particle concentration inside the mask is more than 95% lower than the particle concentration outside the mask. 3M anti-particulate masks all use 3M's proprietary high-efficiency filter material (polypropylene material), which can maintain low breathing resistance while meeting filtration efficiency requirements.

3. Different scopes of application: N95 masks are suitable for medical personnel and related staff to protect against airborne respiratory infectious diseases. 3M's protective masks are designed for use by healthy adults.

Notes:

1. The N95 mask is a mask with a breathing valve. The function of the breathing valve is to use it in hot and humid conditions or when ventilation is poor. Or in a work environment with a heavy workload, using a mask with a breathing valve can help you feel more comfortable when exhaling.

2. It depends on personal use and environment, but when breathing difficulty or discomfort is found, the mask is contaminated such as blood stains or droplets and other foreign matter, the user feels increased breathing resistance, the mask is damaged, etc. The situation needs to be replaced immediately.

3. Users should not blindly wear professional protective masks. Wearing such professional protective masks requires training. If you do not understand this knowledge, it is best not to wear them casually.
