[ The embodiments in which an exclusive property or privilege are claimed are defined as follows:] [1.] A ventilation assembly unit adapted for use with an unsealed housing comprising, in combination:a housing;an air intake port positioned at a base of said housing, said port being functional to receive contaminated airflow therethrough;a fan member positioned directly above said air intake port and immediately downstream therefrom and being functional to blow contaminated air from said airflow in an upward direction at a predetermined rate through said ventilation assembly unit;a filtering medium contained in a canister, said canister being insertable in sealing engagement within said housing and releasable therefrom and being positioned above and immediately downstream of said fan whereby air from said fan passes therethrough;means for retaining said filtering medium within said canister;an intermediate air intake port positioned immediately upstream of said fan and fluidically between said fan and said filtering medium to direct air therethrough;an exhaust port at the top of said canister for venting substantially odourless air after passage through said filtering medium into the atmosphere;said air intake port, said fan member, said intermediate intake port, said means for retaining said filtering medium within said canister, said filtering medium, and said exhaust port being superimposed and in coaxial and fluidic downstream alignment one with another so that fan downstream pressure is applied directly to the interior of said housing and contaminated air drawn from within said housing to which said ventilation assembly unit is attached is filtered and is exhausted as substantially odourless air.
