Should the filter becomes clogged with dust particles, it will reduce cooling fans effectiveness and may result in internal heat buildup and adversely affect the life of the projector.This is an electrically operated long-life auto filter for up to 30000 hours. The projector monitors the condition of the filter at all times and replaces a filter with one automatically when it detects the clogging.
