Magnetic Vent Covers (4-Pack) for Complete Sealing of Residential Standard Floor Vent Covers 5.5" X 12" for Floor Wall and Ceiling Vent Covers RV Residential HVAC and Air Conditioning Vents Black

These are heavy enough and really magnetized!!! GREAT!

These worked beautifully to cover a grill area below my fireplace where cold air was entering from the outside. It is not interfering with the circulation necessary for safety. They were easy to apply and fit the area perfectly and can be removed easily if that ever becomes necessary. The black color matches the finish and the patches are invisible. I am so pleased to have found a solution to a constant winter draft.

It just works on right size and not able to cut off to adjust the size. Good enough to magnetic grab on vent wall and vent floor but doubt works on vent ceiling as not power enough to grab top.

First time ordering these and wish I had these years ago. Solid, the magnets hold in place well and doesn’t leak any air around the edges. Good value for the money.

Yes these work well

It wouldn’t stay on my vents when the air was on. I understand there is some pressure on it but that’s the whole point. I wanted the air to go elsewhere.

I had hoped this would stop air. It will stop some air but isn't strong enough hold to stop the air. It does keep items from falling into the vent if that's what you want it for. I also placed this on a vent on the celling and it stays up on its own. Hasn't fallen down. It's sticky enough. My hope was a stronger hold that stops more air from going through.

The media could not be loaded. These covers are the best! I couldn’t figure out why i was always cold inside the house until i realized cold air was coming from the AC vents. I ordered these covers and now i can walk around without a robe. Now i can save on my heating bill. Works fantastic!
