Does a studor vent let air in or out?

How do I redirect air from a floor vent?
When it comes to accurately redirecting vents, a vent deflector is an ideal choice. Place it over the vent to guide air away from a wall, window treatment or other surface and toward the center of the room. A vent extender, on the other hand, helps move more air out from a vent that’s under a piece of furniture.
Can you put furniture over a floor return vent?
