As noted in previous reviews, these air vent covers aren't magnetically strong enough to cling to an air vent with air coming out of it. Hell, I couldn't get them to stay on even then the air wasn't blowing, much less when it was blowing.

For air returns, these would probably work okay if the magnetics were strong enough to hold it to the register.

If you are using it for floor vents, it is fine, but I have a vent on the ceiling and it does not stay up.

The problem is that when packed three together, the magnetic fields are weakened. I found two covers placed with the right polarity stick to a ceiling vent better. You also need to cut them to the vent size to reduce weight.

It's a good idea but the solution needs refinement.

Unfortunately, these cover are not magnetic enough to support their weight in a vertical position, which is what I bought them for.

All the prior reviews are acccurate and these don't work as advertised for the purposes of covering wall vents. However as weak as these magnetic covers are they can potentially work for you. Here's the solution I found that works ok:

1) First make sure to cut them exactly to size...the smaller the better as this allows them to hold their own weight much better.

2) Double them up. After you cut it to size use 2 covers back-to-back on wall vents. They will hold this way.

If all else fails you can always use those mini-magnets which are obscure and powerful enough to hold these up and get the job done.

The Vent covers were flimsy, and the magnetic coating was weak. When placed over the vent covers, they flew off as soon as the hot air was blowing. A waste of money

We have used them successfully on ceiling registers in an area with strong airflow. As long as you close the register and make sure the cover is trimmed to fit, they stick very well. They can easily be trimmed with scissors or a utility knife to fit the register closely.

But you cannot simply slap on a whole sheet on top of a register and expect it to work. The illustration Amazon shows is very misleading in this respect. If you are not prepared to trim them, don't buy them.

One problem can be registers that have a lot of paint buildup. And of course they only work on steel registers.

If covering the supply registers doesn't cut airflow enough, try covering the returns as well.

Attempted to install these on three ceiling vents. The magnets are not strong enough to keep them connected, even with the air off. Don't waste your time or money. Buy a roll of duct tape and create trailer home ambiance.

DO NOT BUY ANY TYPE OF MAGNETIC VENT COVER, THEY STAIN YOUR CARPET.

A cheaper and BETTER solution is to remove the vent cover and use aluminum foil or plastic wrap and cover/seal the bottom. Then, put the vent back in place. You may get slight air leakage out the sides, but it's still A LOT LESS than these STUPID STAINING COVERS!!!!!!!

TRIED TO PLACE ON A AIR VENT AND THE COVER KEPT FALLING OFF. DON'T WASTE YOUR MONEY.
