High Strength Magnetic Vent Cover For Wall and Floor Air Vents 8.5’’ x 15’’ Double Thickness PACK OF 4- Double Thick To Block Air and Can Be Cut Down To Smaller Size ( Not For Ceiling Vents )

For some reason these covers have a slight curl on both ends and only the middle part adheres to the wall vent. So air escapes from the 2 ends. I only put up 2 of the 4. The 2nd one does not stick at all anymore. I don't know why. I've had these for over a month now. Maybe they would work better for a floor vent.

I don't use my front room. So I bought these covers to help push the warm air into the rooms I do use. These were a perfect fit. Nice weight. I had to laugh when it asked if it was easy to install for the review process. Yes, you lay them down, the magnet does it thing and attaches. Cannot get any easier, unless of course it would unpack itself.

I can't believe that I've just discovered this product. My AC vent got broken and I couldn't block the airflow, so my friend recommended me this product and I am very very happy with the results. The magnets are strong and the vent covers stay in place completely blocking the airflow without any hissing noise.

Wow, they really do stick to wall vents. The short ends curl a little bit and wouldn’t flatten out, but it’s very shallow, hardly affect its performance.Just wish the price was a bit lower for mass produced sheets of magnet.

I use these to keep the vents covered on one end of the house so a lot more heat goes to my Dad's rooms in winter. In summer I cover his vent to keep the cooler air out from the air conditioner.

This is dangerous, it does not stick well. If it falls it the edges are sharp. It will not hold and might fall on your head.I already Tried a few things and cut the edges trying to make it stick. But not worth the risk. Went in the trash.

They were sturdy, but they didn’t stick to the vent. They kept falling off, so I had to duct tape them onto the vents. I am very disappointed.

As long as you cut these to the size you need they adhere well and keep the draft out.
