Magnetic Vent Cover –8" x 15.5" Extra Thick Wall/Floor/Ceiling Vent Covers (4-Pack) That Will Reduce Sound, Very Flexible, and Will Stick to Your Vents – Made from Premium Magnets by Kelbert

These are quality magnetic vent covers. They are weighty. They have some heft to them; they are not cheap which was exactly what I was looking for to do the job. I only needed about 1/2 the size of one cover. The area I needed covered was a vent in my shower directly above the shower head. There was a lot of strong air coming out of the vent, the sound of the air was loud, and it was cold which made it very uncomfortable to shower. The entire vent measures 8" x 8". All I needed was a pair of scissors to simply cut it with ease to fit, no problem. I stood in the tub and applied the vent cover to the vent and the sound and forced air coming out stopped immediately. I was totally amazed and am so grateful that this issue is now 100% resolved. Now I can go into my bathroom without the extra air and annoying sound. It's wonderful to have a normal bathroom. I also appreciate the little message in the package from the Kelbert family. It shows that they care and do good business. I will hang onto the message and if I need anything again, I can refer to it and use the email address they provide. So yes, I would for sure share their information with anyone that has a need for their products. I am a very happy customer. Thank you, Kelbert family.

I bought these for my uncommon ~4x15 vents (outside measurement) on the ceiling downstairs because it gets way too cold down there when the air conditioner is running to keep the upstairs comfortable. The magnets are very strong. They stick well to my ceiling vents, even over the screws used to mount them. I tested with the air conditioner running and they show no signs of coming off.I did cut these in half with a 15-inch ruler and a utility knife. I scored lightly along the white side, then folded in half slowly (white side out) until the two halves were flush, then folded in half the other way until they snapped apart. They fit perfectly without any further modification directly over the vents. They are very white, so be aware of that if you're concerned about the color matching your paint.I've never bought vent covers before, but these are a quality product and I'd buy them again without hesitation if I needed more.

I tried a brand from Home Depot & it was TERRIBLE.I saw that this Vent Cover was from a small family business and felt like they were much more likely to product a quality product and I was 100% right.The owner could literally sell a x2 set of these for $20 and they would still be better than thecompetitors on the market.I bought this for a large CEILING vent register, NOT the floor or the wall.It took me a lot of time doing product research before I settled on the "Kelbert" Brand but it was 100% worth it.What stood out to me- Product Quality- Thickness- Magnetism StrengthI did actually spend a lot of time cutting these to perfectly fit my vents but I wouldn't have rather done that with any other product on the market.*You will have to cut it to perfectly fit your vent in order to have the best direct connection for optimal air tight results.Even thought this looks like a bot might have written this, it was 100% a real review, lol.(Wasn't in the mood to upload a picture but I did 100% use these)

I love this product it worked exactly how it should I have no issues with how it works my issue is after several months I noticed the panels are losing its magnetic hold it’s getting weaker for some reason. I have them over a grate in my bathroom going vertical and now they are starting to slide down but not by much

I live in the basement of a house and its always cold downstairs. I bought these to cover up the vents so the AC wouldn't make it freezing down here and these have been a perfect solution. You can cut them to size with regular scissors and even cut out a notch easily for the vent adjustment knobs. The magnet is plenty strong. They never fall off, even when I put it on the main vent with the strongest air flow and they are also easy to remove when you don't need them anymore. They also work well for keeping noise from going between 2 rooms as it blocks most of the noise from travelling through the vents. Great purchase.

These magnetic vent covers were expensive, but worth it. They completely seal the vents and do not fall off when used on wall or ceiling vents. They are very heavy, but the magnets are so strong that they do not budge once placed. Also nice is that the material is flexible so that it will contour to bulges or imperfections in the vent grate. I did end up making cuts in the covers so that the wheels knobs that open/close the vents does not create so much of a bulge that air would leak. I give these a 10/10. Only downside is that they are a bit expensive. But for me, totally worth it since they work so well.

Used this to cover metal vent in my kitchen, works great.

I needed these because in the winter, when the warm air blows on my bed, it wakes me us every time. I close the vent, but covering them lets me get uninterrupted sleep, even though other members of the house prefer a warmer temperature. . These vent covers are twice as thick as the ones I purchased from a home improvement store. I was surprised by the heaviness of the box. I worried they would not stay on, or be too hard to trim. They are perfect! Trimming was earlier than I expected with regular scissors.. They clung to the vents like passengers to life vests on a sinking ship. Problem solved.. I can see their thickness and sturdiness would be perfect for use on floor vents too. Highly recommend these.
