Abstract: A system for air decontamination in a three-dimensional space described herein includes an air inlet for drawing in air, an air outlet for administering filtered air, and a filter device for filtering air prior to administration through the air outlet, the system is configured to draw air in a substantially vertical laminar flow from a ground of the space to the air inlet. A filter device for filtering ultrafine particles from a gas described herein includes a first filter medium for absorbing polar liquids but not ultrafine particles; in fluid communication with a second filter medium for absorbing ultrafine particles; and a gas outlet, the first filter medium is configured to allow vaporization of the absorbed polar liquids; the device is configured to guide the gas from the first to the second filter medium and through the second filter medium; and the second filter medium forms the gas outlet.
