What's the Cheapest Way to Purify The Air in a Dusty Room?

Question

I have to clean out a dusty room that has windows on two walls. I was going to get an air purifier, but they are way to expensive. Is there a cheap way to get all the dust out? Maybe with a spray or a natural way or technique??? Thanks!

Answer 1

Get a dust mask for yourself, a couple of box fans in the windows, a vacuum cleaner to the ceiling, walls and floor. Use the box fans as exhaust units to get the dirty air out. then when you are done with the cleaning, use the box fans with furnace filters and a moist towel to trap the dirt from the air.  Put the moist towel between the fan and the filter on the intake side of the fan.  This should get most of the dirt out of the room.  It will also help hunidify the room and settle the dust. Total outlay less than $100.
