At present, most cases of VOVID-19 are transmitted indoors, and these infected people inhale particles containing viruses in the air. In order to prevent the virus from spreading at home or in the workplace, it is best not to let the virus enter our living and working areas.

But it is very difficult to completely prevent the spread of the virus, because 40% of the cases have no symptoms, but they can still pass the virus to others, which is difficult to avoid. Although it is very difficult, there is one thing we can do, and that is to maintain indoor air circulation and constantly add fresh air.

As the fresher and clean air enters the room, the more it can dilute indoor pollutants, such as viruses, and reduce human contact with viruses. Not only in the period of COVID-19 outbreak, but also in the general flu stage can effectively resist infection.

There are two ways to improve indoor air quality:

The first is to keep the room ventilated and ensure that it is ventilated at least once every morning and evening, and the ventilation time is at least 30 minutes.

Using an air purifier, the best choice is a purifier that achieves a high-efficiency air particulate filter, and then select the corresponding efficiency purifier according to the size of the room and the number of people.

Both the WHO and the US Centers for Disease Control and Prevention have stated that poor ventilation increases the risk of the spread of the2019-nCov.When the temperature drops and the indoor heating continues to open, the environment we live in will become more muggy, which also poses greater challenges to the epidemic prevention work.Therefore, to use methods within our capabilities to improve the environment is to protect ourselves.
