3. Will the detector cause cross-infection when multiple users use it?

According to the principle of the infrared temperature monitor, the body temperature can be measured without touching the skin. During the measurement, both the measuring person and the measured person are wearing masks, so the risk of cross-infection is very low.

4. Can the air purifier filter viruses?

At present, the air purifier commonly used in the market is composed of a fan and a filter device. The fan is to inhale the air in the home, while the filter device is to remove various pollutants by adsorption and then discharge the filtered air.

So, air purifiers don't necessarily filter out viruses.

It is recommended that under normal circumstances, the family carries on ventilation to the indoor air every day, through natural ventilation or mechanical ventilation, but in the current temperature is lower, window ventilation should pay attention to the risk of cold caused by large temperature difference between indoor and outdoor.
