Abstract: An image projection device includes a replaceable air filter placed near an opening of a housing, a switcher for switching step by step a working area of the air filter, an air-speed meter for detecting a pollution level of the air filter, and a controller for controlling the switcher. When the air-speed meter detects that the pollution level of the air filter reaches a given threshold, the controller prompts the switcher to switch the working area of the air filter, and then detects a pollution level of the air filter after the switchover for determining whether or not the working area before the switchover needs to be switched.
