Abstract: A vapor catching method and apparatus which catches approximately or nearly 100% of visible secondary vapor produced from an electronic cigarette is disclosed. A device embodying the method comprises a casing having an interior space for housing a vapor filter. The casing comprises a vapor intake opening and an exhaust port. The secondary vapor is exhausted through an appropriate filter system housed within the filter casing. In use, an electronic cigarette user sucks vapor through the lip end of an electronic cigarette product and exhales the vapor into the vapor intake opening of the vapor catching device which filters the various vapor chemicals allowing only clean filtered air to pass out of its exhaust port.
