so good buying more
Have used 3 last year, mainly for shutting air vents in bathrooms. One now needed for vent in living room as now I stay cold all the time. So back for more. What I love is that I can remove the bathroom ones in winter when heat is needed and put back in summer so I don't freeze when I get out of the shower.

These covers do help keep the furnace duct work clean during the summer, which is a big help, and they stay in place - a definite plus.

Does the trick
Conveniently covers vents to keep chilly air from blowing directly on me when I'm sitting in the kitchen or den. Strongly enough magnetized to hold firmly in place. Sturdy construction. I would recommend these. Downside: handling charge added to the shipping plus the tax made this product cost twice as much as the listed price.

This covers a heat vent built into the floor that we prefer not to use. The cover is cut to size, placed on top of the closed vent, and an area rug covers that nicely. Over time, because of repeated foot traffic, the cover has deteriorated slightly, thus the reason to replace it. It's a very inexpensive fix!

Ducts in my small bathrooms leak air even when they are closed so the covers help keep the rooms comfortable. My ducts are small so I can cut them to fit. I've been looking for these cover for a long time.

I have weird sized heat vents and couldn't find magnetic vent covers to fit them. I saw these and the size they were so I ordered 2 sets. I cut them to fit my vents and they were perfect! They are ceiling vents and these hold very well!

Some of my heater/cooling vents are difficult to close completely. Some are located on a high ceiling that needed a ladder to close. Used one to absolutely close the vent directly under an antique cabinet.

In the summer, it sometimes gets too cool in some of my basement rooms, so I need to block the air from the vents.

Thought this might work better than duck tape.
LJay C on May 22, 2018
I live in a mobile home with floor vents. In the summer, the air beneath is warm; in the winter, it's cold, although it's where the heat comes into my rooms. But during hot weather, the hot air isn't welcome, and in winter, all rooms don't always need the warmth. I'm hoping these gizmos will allow me to control this better, and have a tighter rein on my utility bills.

Judy H on Dec 4, 2016
To save a sizable amount on my winter heating bill. I can now turn off the electric heat and use space heaters in the main rooms and cover up the floor vents where the fan puts out cold air, even when the heat is off. This item is extremely hard to find. So glad you had it. Folks, buy them while you can. It is great investment.
