I do my painting from home. and i have alot of ventilation and I have created my 25x25 steel building into a positive pressure filtered air booth. there is only an Intake fan with large filters and then my exhaust (which doesnt have a fan has filtration as well as the outgoing air gets directed into a trough of water to collect any un filtered paint still in the exhaust air. This makes my painting more neighbor friendly. LOL.
