US Patent 9162173 Air filtration assembly

An air filtration assembly for selectively eliminating smoke from an area includes a housing that may be coupled to a support surface. A motor is coupled to the housing. A fan is operationally coupled to the motor. The motor moves the fan. An actuator is coupled to the housing. The actuator is operationally coupled to the motor so the actuator selectively actuates the motor. A filter is coupled to the housing. The filter is operationally coupled to the fan. The fan draws air through the filter so the filter removes smoke from the air. A screen is operationally coupled to the housing. The screen is selectively extendable from the housing.
