I have a room that isn't being used and want to block the a/c when we don't need to access the room to save on a/c costs.

I needed to replace the ones I bought 20+ years ago. The ones I had lasted but just got too dirty with age.

I need to stop airflow in my closets.
Elizabeth H on Jun 7, 2018
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.
Catsissie on May 14, 2018
i dont use all rooms in my house. i cant see cooling all of them.

Needed to cover vents to prevent air conditioning from going into basement and not make it to second floor. Worked very well.
Jerrilynn l on Mar 6, 2017
Good idea
Amanda R on Feb 27, 2017
I have birds they do not like cold air on them in the summer and in the winter have some in house that don ;t want their room warm so block it
LINDA LORENE G on Feb 22, 2017
We open our bedroom window and close the registers, but some heat still leaks in and the cold air also can activate the furnace to run
M R on Feb 9, 2017

Rachel S on Jan 31, 2017
The heat in my office is unbearable. With these magnets [which I have had before], I can send the heat on to the next office. These WORK!

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.
Debborah C on Dec 1, 2016

Laura H on Jul 3, 2016
Need a solution to a small vent & Miles Kimball has always provided good products!
Barbara M on Jun 29, 2016
If a vent does not close or stay closed this is wonderful.
Pamela P on Jun 8, 2016
I have a vent over my AC and it pulls all the cool air from this solves the problem.
P E on May 26, 2016
Chosen for obvious reasons--to block, or partially block some vents. Works so-so. Magnetic hold isn't strong enough to keep the cover down when the A/C or heat comes down if the whole vent is covered. It sorta stays down if only half the vent is covered. Have to put a rock on the cover if the whole vent is covered. I was definitely hoping for more...
LINDA S on May 6, 2016
been looking forever, and finally found you
Beth K on Apr 20, 2016
They don't work!! Just the air that flows from the vent blows it off. Not near enough magnetic power. Threw my away.
S J on Apr 17, 2016
We have them in the office but the supplier can not get them any more, so I looked on line and found you guys! Thank you!
Janet B on Apr 13, 2016
In the summer, I can put these on the vents downstairs so that the upstairs is cooler. In the winter, I can put these on the vents upstairs so the downstairs stays warmer.
H E on Apr 1, 2016
Have had these covers in the past and am glad to have more. They are a big help keeping dust and dirt out of the vents and duct work.
GLENDA S on Mar 29, 2016
To reduce heat and air in two rooms that do not need either.
