Frost King Magnetic Vent Covers, 8" Wide x 15" Long, White

Needed covers for cold air coming in vets. The best thing about these for me, is that the materials did not smell toxic. I am sensitive to chemicals, and magnetic sheeting usually smells, but not these.

can cut to size if needed.

The product works for floor vents, I bought it for wall vent. Will need to exchange for correct item

These have significantly reduced my AC costs. I live in a quad level. Custom sized each one and placed on the ceiling vents in the lower level. Now the cold air blows upstairs and cools the house efficiently. These are strong enough to hold to ceiling vents, just need to press the whole surface on at once.

They are very nice and they serve the purpose

I got this for covering vents. I was surprised at how well made it was. Nice and thick and the magnet works great. I'm very happy with this purchase.

Did not stick properly or work on ceiling metal vents. Will work good with floor vents.

Total waste of money. I can not speak on if these work for floor or wall vents but, for ceiling vents, they do not work. They are too heavy and the magnet is too weak to hold them in place. Extremely disappointed.

This is the worst purchase. They do not even stay on, we tried taping them but as soon as the heat kicks on it pushes the tape off and as you can see in the picture is just a flap. This is the weakest magnet ever and such a disappointment.

As others have stated, the vent covers do not stay on vent. They shouldn't even be called magnetic since it's deceiving. I'm returning mine and will look for ones that actually work.
