There is provided a system for cleaning a contaminated airflow. The system includes a macro-contaminant separator that creates substantially macro-contaminant free airflow, a micro-contaminant separator that creates a substantially contaminant free airflow from said substantially macro-contaminant free airflow, and a germ controlling device that kills or controlling any germs remaining in the substantially contaminant free airflow. The macro-contaminant separator may be a cyclone-type contaminant separator. The micro-contaminant separator may include a micro-particle filter, an odor adsorber, or both. The germ controlling means may be an ultraviolet light source.
