According to China Press, a recent study by Swansea University in the UK found that if the windows are opened regularly for about 10 seconds and wearing masks, the number of coronavirus particles can be reduced by about 97%, which can greatly reduce the risk of infection in cars.
A few days ago, the British Broadcasting Corporation (BBC) reported that a study by Swansea University found that in addition to the “droplet infection”, the air transmission route in COVID-19 also includes the “air gel transmission” through the aerosol produced when the infected person breathes.
Among them, saliva, snot and other droplets containing water are heavier than aerosols and can fall to the ground in just a few seconds. However, if the aerosol evaporates, the virus can circulate in the air for up to 1 hour.
According to the research, if you are in a car, you can effectively reduce the risk of infection through the difference in air pressure! It is reported that Li Chenfeng, a professor in charge of research at Swansea University in the UK, revealed that the air can circulate more effectively through the air pressure difference between the inside and the outside of a moving vehicle, and the virus in the vehicle can be discharged! If the speed is slower than 48km/h, the ventilation effect is best when all windows are opened.
However, when driving at high speed, the increase of air pressure difference will cause a “tunnelling effect” on the diagonal window, which will make the suspended particles more effectively dispersed. Therefore, at higher vehicle speeds, diagonal windows should be opened instead of all windows.
Li Chenfeng emphasized that this method is very effective. Every 5 to 10 minutes, or when someone coughs or sneezes in the car, it only takes 10 seconds to ventilate, which can reduce the accumulation of virus particles by about 97% and greatly reduce the risk of infection in the car.
However, Li Chenfeng also cautioned that this method should be matched with “wearing a mask all the way”, which is the best method for in-vehicle epidemic prevention. The results also show that wearing masks can reduce the number of viruses in the air by about 90%, and the passengers’ intake of viruses can be reduced by about 70%!
You can also follow the above methods when driving, which can fight against viruses more effectively!
