These are flat magnetic sheets that stick over metal HVAC vents to shut off or redirect airflow in a room. Each cover measures 5.5 by 12 inches and can be cut with scissors to fit smaller registers. They suit homeowners balancing uneven heating or cooling, or anyone closing off unused rooms. Compared with plastic snap-on vent covers, magnets install without tools and leave no screw holes, but they only hold on steel vents and can be trimmed away by mistake.

Buyers rate these covers well for fit and easy installation on standard steel registers. Complaints center on weak hold on some vents and the need to trim carefully.
These magnetic vent covers block and seal metal vents in the floor, wall or ceiling. They restrict air flow from HVAC vents and redirect warm air in winter and air conditioning in summer.
Each cover is a rectangle that measures 5.5 inches wide by 12 inches long. It is magnetic, so it attaches securely to any metal vent. It fits large side vents and can be cut to size.
The cover can be painted, stenciled or wallpapered to match your décor.
