Will mosquitoes enter the outer circulation of the car?

The external circulation of the car will not enter mosquitoes, and it is protected by a filter. When the air is good, the external circulation can be properly opened. This also contributes to health.

The external circulation state is to use the fan to suck the air outside the car into the car, that is to say, the air channel outside the car and the inside of the car are circulating, and the air from the fan comes from outside the car. Sometimes I feel that there is still wind when the fan is turned off, because the owner has set up the external circulation. When driving in the city and encountering congestion, the car will be filled with tail odors, which is caused by the use of external circulation.

The internal circulation state is to close the airflow channel inside and outside the car, there is no airflow circulation without turning on the fan, and the airflow inhaled when the fan is turned on only comes from the inside of the car, forming the airflow circulation inside the vehicle. The internal circulation is mainly to prevent external dust and harmful gases from entering the car in a timely and effective manner, such as blocking the harmful exhaust gas discharged by the vehicle in front of it through smoke, dust, odor areas or when the vehicle is driving densely and compactly. Another function is heat preservation.

Internal circulation for traffic jams.

The outer circulation of the car does not bring in mosquitoes because there is a filter. So rest assured.

This won't happen, it's all the air conditioning system working, and there is no chance of mosquitoes getting in and out.

The outer circulation of the car, under normal circumstances, will not remember the name, rest assured, the external circulation of the car, under normal circumstances, will not remember the name, rest assured, will not.

If you don't open the windows, the inside of the car is still relatively sealed, and mosquitoes will not enter.

Yes. Because the external circulation state is to use the fan to suck the air outside the car into the car, that is to say, the airway outside the car and the inside of the car are circulating, and in the dusty road section, or windy weather, in the external circulation state, the dust blown by the wind is easy to enter the car, so that the dust in the car increases.

The internal circulation is mainly to prevent external dust and harmful gases from entering the car in a timely and effective manner. Therefore, the use of internal and external circulation should be combined with air conditioning and heating.

For example, if you drive at high speed, you feel that the air in the car is turbid and uncomfortable, and you can't open the window, so you should use the external circulation to get some fresh air in. In winter, if the heater feels too hot, you can turn off the fan and turn on the external circulation, which not only maintains the temperature in the car, but also has fresh air. If the air conditioner is turned on to reduce the temperature in the car, do not turn on the external circulation at this time, but turn on the external circulation at intervals to replace some fresh air.

In addition, when driving in the city, traffic jams during rush hour, especially in tunnels, should use internal circulation as much as possible. When the car starts to drive at a normal and constant speed, it should be turned on to the external circulation state. When encountering dusty road sections, don't forget to close the external circulation to block the external airflow while closing the windows.

It is best to set it to an internal circulation state when parking at ordinary times.
