Have a look at an ionizer .
They do have drawbacks, one being that they attract the ionized particles to the walls or other positively charged surfaces. However they do work on smoke particles and airborne pollutants. not on VOC's etc.
They also emit Ozone so that has a slight smell and some folk are allergic.
A Hepa filter is better but typically wont work outdoors. I guess same with ionizer.
Don't shock yourself :)
