There is provided a system for cleaning a contaminated airflow. The system comprises a macro-contaminant separator (20) that creates substantially macro-contaminant free airflow, a micro-contaminant separator (50) that creates a substantially contaminant free airflow from the substantially macro-contaminant free airflow, and a germ controlling device (61) that kills or controlls 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 (51a), an odor adsorber (51b), or both. The germ controlling means may be an ultraviolet light source.
