Can the humidifier be on all night? How long does the humidifier last best?
If the air is dry, you can drive all night, which is not harmful to human health.
The humidifier is mainly used to increase the indoor humidity. As long as the room is dry and the air humidity is lower than 40%, the humidifier can be opened all the time to increase the air humidity. However, if the air humidity index exceeds 60%, it is not suitable to continue to open the humidifier.
Generally, it is appropriate to maintain the indoor humidity at 40 ~ 60%. The humidifier can be used intermittently during startup. Those who are at home all day, 2 ~ 3 hours in the morning and 2 ~ 3 hours in the afternoon; The startup time can be appropriately extended at night.
The humidity in the south is generally better than that in the north, but as more and more families use air conditioners, electric heaters and other heating tools in winter, the indoor humidity is also greatly reduced. Therefore, if conditions permit, it is best for families in the south to use humidifiers in winter.
