ABSTRACT:
There is herein described an improved laser smoke particulate/odor filter including an upstream gross particulate portion that both filters and disperses the smoke, a single charcoal odor adsorption portion, a downstream particulate portion for removing smaller gross particles, and a final filtering portion for filtering out any remaining undesirable contaminated particulate. Another embodiment utilizes an upstream particulate portion that filters and disperses the smoke followed by a first and second charcoal adsorption portions of unequal sizes that are separated by a second smoke dispersion member disposed between the first and second charcoal odor adsorption portions.
