Our take on the Mc815-3 Magnetic Vent Cover 3 Pack

This is a three-pack of flexible magnetic sheets sized 8 by 15 inches, made to stick over metal floor, wall or ceiling register vents and block or redirect airflow. The magnet holds to the steel grille without screws or tape, and the sheet can be trimmed to fit smaller vents. It is a low-cost fix for rooms that get too much heat or cold, not a powered deflector. No current store price was provided, so check the live comparison before buying.

Questions and answers

Will it stick to my vent?
Only if the grille is steel or another magnetic metal. Test with a fridge magnet first. Plastic, aluminum and painted wood registers will not hold it.
Can I cut it to fit?
Yes. The flexible sheet can be trimmed with household scissors to fit smaller vents. Cut slightly larger than the opening so the magnet has metal to grab.
Does blocking a vent save energy?
It can redirect air to rooms you use, but fully sealing many vents can raise pressure in the ducts and strain the blower. Close a few, not all.
Is it better than a plastic deflector?
A magnetic sheet blocks or partly covers a vent. A deflector aims the air. If you want air sent toward a sofa or bed rather than stopped, buy a deflector instead.
How many vents does the pack cover?
Three, one sheet per vent at 8 x 15 inches. Larger registers may need two sheets or trimming to fit.
