Many people think that turning off their air purifier when they are not present or during the night is a sensible energy-saving measure. However, it is actually recommended to keep it running constantly. Some air purifiers have the function of releasing ozone and increasing humidity, so special attention should be paid to this. Leaving an air purifier on all day or running it around the clock can cause the indoor ozone concentration to exceed the standard, and the humidifier head is prone to bacterial growth.
Therefore, it is not recommended. You can identify if ozone is being produced by checking if there is any odor in the air outlet after letting it work for a period of time. For optimal performance, all air purifiers must operate continuously. When the air purifier is turned off, indoor air pollution returns to its original state.
This way, you can ensure that your home's air quality remains high at all times.
