Is the air in the car safe enough to remove the mask?

The new coronavirus can survive in the air for a long time and can also form aerosols for large-scale transmission, so personal protection is required. But the problem is that we basically wear medical masks when we are outdoors and do a good job Protection, when we are in a private space, we often subconsciously remove the mask, such as in the car interior. But is the air in the car really completely safe?CN95 Cabin FilterThe manufacturer tells you the answer:

The air entering the interior of the car needs to pass through the car air conditioner filter. Generally, the diameter of the virus is only 0.06-0.14 microns, so when we are in the car environment, the conventional car air conditioner filter can only filter larger dust particles, which are called inhaled particles or airborne dust.
Refers to particulate matter with an aerodynamic diameter of less than or equal to 10 microns. It is often heard that there are PM1, PM2.5, PM10 and other pollutants. Long-term accumulation of PM10 can cause respiratory diseases, such as shortness of breath, cough, asthma, chronic bronchial inflammation, chronic pneumonia, etc.
However, conventional air conditioner filters are not enough to protect against viruses, so it is impossible to ensure that the air is absolutely clean. Therefore, it is necessary to replace the CN95 air conditioner filter element to improve the filtration level of air particles and do a good job in the prevention of new coronary pneumonia.
The current domestic situation of the new crown pneumonia epidemic is still not optimistic. With the return of overseas Chinese living abroad, another wave of infection may be brought. Therefore, the virus has not completely disappeared, and we still need to do a good job in safety protection.
