Abstract: A purification system for preventing secondhand tobacco smoke from reaching an ambient environment thereabout. Two components of the system include a smoke entrapment intake hood for aggregating the secondhand smoke and an electrostatic suction filter assembly in communication with the entrapment hood for extracting aggregated smoke from the hood, removing untoward particulate from the smoke, and releasing resulting clean air to the environment. The filter assembly includes at least one particulate filter for collecting smoke-borne particulate and at least one appropriately charged or grounded plate for electrostatically collecting charged smoke-borne particulate. An exit port from the filter assembly permits the release of so-cleaned air to the environment as a negative-ion emitter, positioned immediately inside the exit port, introduces charged ions into the cleansed air.
