Chinese National Standard GB6223-86UDC614.894:
Except for the Japanese standard (0.06-0.1 microns), the above inspection standards are tested with a particle size of 0.3 microns.
The EU standard test flow rate is 95L / min, and the US standard is 85L / min. China's national standard uses a suspended particle size of more than 90% of less than 5 microns, more than 70% of less than 2 microns, and a flow rate of 42.5L / min. In the testing and certification of filter media, the "worst case" idea is adopted, that is, the conditions when the laboratory is doing the testing experiment are set to the worst conditions

The activated carbon in a good chemical filter box should be packed densely, with a small particle size and a large specific surface area, so that the anti-virus time will be long.
At the same time, it must also consider the small breathing resistance and comfortable wearing.
1. The mask is contaminated with foreign objects such as blood stains or droplets.
2. The user feels that the breathing resistance becomes greater.
3. The mask is damaged.
4. Dust-proof filter cotton, when the mask is close to the user's face, when the user feels that the breathing resistance is very large, it means that the filter cotton has been filled with dust particles and should be replaced with a new one.
5. Anti-virus filter box, when the mask is in good contact with the user's door, when the user smells the poison, it should be replaced with a new one.
6. Ordinary masks wear: activated carbon masks can generally be used for 2 days, n95 can be used for a week. If the mask has not been worn for a long time after cleaning, it is better to wear it again.
