What is a ceiling air vent deflector?

Ceiling air vent deflectors are devices that fit over air vents, diverting airflow away from the ground and across the ceiling line. Some air vent deflectors are fitted with filters to help with air quality.

Ceiling air vent deflectors help users avoid cold drafts that cause illnesses in the workplace and help to maintain a clean ceiling. Deflectors are made of either light metals or plastic, usually weigh less than 3 pounds, and can easily be installed or removed with no tools at all. Air vent deflectors also preserve the circulating air volume within a room while maintaining the balance of its ventilation system.
