I need to rid the air in my shop of dust, best suggestions?

I own an electronics repair shop. However, it is very dusty in here. I would really like to purify the air of any dust or dirt, so it does not settle on electronics waiting for parts and what not. I am basically wondering… Products like the Ionic Breeze Air Purifier… do they really work to get rid of all the dust? I once saw a friend had one in his house when his mother was on oxygen and she couldn’t breathe in any dust at all.

So should I look into getting an Ionic Pro, or is there another product I should look into, I would rather not spend TOO much, but I don’t see anything near 0-0 being a problem investing in.

Thanks for any help, it is much appreciated.
