It is possible to hang a towel above a ventilation vent and let it catch the air’s moisture as it passes by, or place a bowl of water near the vent. If you allow the room to become overly humid, you run the risk of developing a dampness or mold problem.

Is covering a vent a fire hazard?
Because less cool air can pass through the heat exchanger when a vent is blocked, the heat exchanger becomes overheated and expands, eventually cracking. There was a huge bill and a cold house, and the homeowner was unhappy. Blowing hot air into the furnace by blocking a heating vent could result in a fire, but it’s not out of the question.
What happens if you cover a vent?
If you do block the airflow from your vents, there will inevitably be a buildup of air pressure. Eventually, your heat exchanger will crack and release carbon monoxide into the atmosphere.
Can you safely cover an air vent?
Low airflow can cause problems with your heat exchanger, causing it to crack and emitting carbon monoxide if pressure builds up from air being pushed to covered vents.
Can I cover a floor vent with a towel?
The fact that a room is unoccupied should not be a reason to cover vents. In the condition space, it is not yet ready for use. If the only reason you want to cover it is because it has a lot of airflow, then yes.
What can you cover a vent with?

Can you cover a vent in a bedroom?
If you look closely, you’ll see a space between the inner and outer skins of the walls, or what would be the exterior equivalent of a duct. It’s fine to cover the inner skin if there is a gap between the two skins. If it’s like a duct, then I’d also seal off the outside.
