Surgery plume filter device and method of filtering

A filter device for treating an airstream containing gaseous and particulate materials from a surgery plume comprising:

• an elongated filter body having an inlet port and an outlet port and an airstream passage therebetween for accepting and exhausting the surgery plume airstream;
• an internal solution reservoir formed inside the filter body and positioned in-line with the airstream passage to fill a portion of the passage for intercepting the airstream;
• a charge of a reactive solution being contained within said reservoir;
• a rupturable membrane positioned in the airstream passage for sealing said internal solution reservoir, said membrane being rupturable upon impingement by a flow of the airstream in said airstream passage;
• the intercepted airstream and the reactive solution operably interactive for forming and breaking down a foam inside the filter body;
• the filter body configured to contain the foam and expose the airstream to the foam for a time period sufficient to effect removal of gaseous and particulate materials from the surgery plume airstream;
• whereby the filter device exhausts the treated airstream into the atmosphere through the outlet port generally cleansed of certain agents in the surgery plume.
