More Information
Summary:The present invention is directed to a filter device for filtering ultrafine particles from a gas comprising 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, wherein 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. The present invention also encompasses associated uses and methods for filtering ultrafine particles including systems for positioning and integrating the inventive filter devices.
