What does the Levoit air purifier red light suggests(not on filter ) ?

If there is continuous red light on the Levoit air purifier then it suggests that there are too much pollutants in the air and the air purifier is taking some time to clean the air of the room.

In order to fix this the air purifier will increase its speed for sometime until all the pollutants are removed and will be back to its normal speed once the air is cleaned.If you want,you can also increase the its speed manually .

Once all the air pollutants are removed the colour of the right will be green and then turn to blue.

Even after certain time like couple of hours if the red light is still there on the air purifier then it suggests that the air inside the room where you have kept the air purifier is very polluted and is beyond the technical capability of the air purifier.

This can be checked by moving the air purifier to a different place which is less polluted than the previous one and checking the light status.

Also make sure that the air purifier is not kept near the vent or a window as the air near the vent contains more pollutants.
