Abstract:
1. A method of collecting airborne particles into a liquid solution, the method comprising: a. rotating fan blades in a first rotational direction, thereby generating airflow past the fan blades in a first direction, wherein the airflow includes particles to be collected; b. collecting the particles on the fan blades while rotating the fan blades in the first rotational direction; c. rotating the fan blades in a second rotational direction at a first speed, thereby generating airflow past the fan blades in a second direction; d. dispensing a fluid onto the fan blades while rotating the fan blades at the first speed, wherein the fluid and the particles are centripetally forced to the edge of the fan blades; and e. rotating the fan blades in the second rotational direction at a second speed, thereby forcing the fluid and the particles into a fluid collector.
