    The windows are open

    If the windows are open and polluted air continues coming in from outside, your purifier might not be able to improve the air quality.

    Make sure that all windows are closed.

    The room is too big

    The room in which you run the air purifier is larger than the maximum size at which this air cleaner can operate effectively.

    Make sure the size of the room does not exceed the maximum indicated for your air purifier model.

    New furniture in the room

    When adding new furniture to a room, the air quality might become affected by gases it might emit. These gases should disappear gradually in the next weeks.
