Why do i head a humming sound when the device is in use ?
There is a fan located on the back of the air purifier that sucks air through the filter and blows our clean air. Don’t worry, it’s normal.
Where in the room should i place the Air Purifier for optimal results?
What if my room is larger than the effective area?
Do you have any other efficiency tips?
How can i switch off the night light?
