It's getting rid of all fine particles emmited by airbrushes. The working area is good for 28mm (1:56) scale models. Lighting on the other hand is very dim. Clearly not enough and extra Lighting is needed. The sound level emmited by the fan is really loud and the fan speed is not adjustable. The fact that it's easily collapsible and has a top handle is surprisingly handy and allows me to store it away from sight when not in use. It takes no more than 30 for the process.
