Adjustable Air Conditioning Vent Cover

To my surprise, this actually works. It was easy to install and it appears to be made of quality materials. My office air vent is the type with concentric square vent blades: a small square in the middle, then larger squares as you out, of the overall size that Teak Isle specified their cover is made for. Their vent cover cuts out about 90% or 95% of the air flow. The only slight weakness is that, at least on mine, to open or close their adjustable vent cover you have to use some force; it is not easy but I soon got the hang of it. That may be unavoidable, as if it were looser it may cause problems? Perhaps not. I also have to stand on a desk to reach the vent cover to open or close it, but that's a different matter. I usually stand first on a solid chair, then go from the chair to the desk.... I go nice and slow. I don't think you could open or close it using a broom handle while standing on the floor. It requires too much pressure. Our department manager is small and not so agile; she has not ordered one because of the adjustment issue. On the other hand, I assume most people would rarely need to adjust it once they go the size of the opening right. This vent cover worked so well completely closed that my office began to smell stuffy from lack of air flow, so each evening before going home I open the vent up again. My problem is actually not being cold. I have dry eyes, and the breeze from the open vent was not so pleasant. Teak Isle solved that problem and I am grateful. I have read elsewhere that one should not block too many vents on your system as that could damage things.

I ordered these for our offices as there was a girl that was always freezing in her office regardless of what the temperature was set on. We installed two of them in her office and completely blocked off the air flow into her room. They work very well, her room stays much warmer even when the A/C is running. They actually work so well that my boss wanted some for his office after we installed the first set. Now that their offices are nice and comfortable my office feels like a walk in freezer, due to more air blowing out my vents. The servers, DVRs and a lot of other computer systems are in my office though, which is good for them, so I just bundle up and keep myself warm. If you are not just trying to divert the airflow and actually want to stop the flow of air entering specific rooms then I suggest these simple to install air blocking vents. There are no tools required to install and they took me one or two minutes to install.

Although I feel it's too expensive, it's the only product available like it. I'd give it 5 stars except they cut one too many corners and it came up just a tad too small. I installed it easy enough by pushing up on the vent cover and slipping it in the grid. However, it kept slipping out due to it being just a tad too small. If I pushed it into one corner it would slip out of another. To correct the problem I bought some metal braces at the local hardware store and slipped those into the corners to keep it from slipping out. That fixed the problem. Now I can open and close the vent without it slipping out. Bear in mind, if the air pushes through your vent as hard as it does in my office, you are going to hear white noise when the vent it closed. I would rather have the noise than the cold air. I included a picture of it with the braces. I bought 3 different sizes of braces to see what would work. They all work, I would need at least 2. I intend to remove them one at a time and spray paint them white so they will blend. Overall I'm happy as I've been looking for a solution like this for years. If I change jobs, I'm taking it with me!

This is exactly what I needed to keep me from freezing all day, every day at my desk. They fit perfectly over the vents above my desk. I was able to install them myself by popping them in...no tools and no talent needed. lol Two hours after they were in I had someone in my office asking about them. Another hour later our fixer guy asked me to order 4 more because the girls were bugging him to install them over their desks/vents. If you have air blowing on you and you're tired or being cold while at the office I would highly recommend this cover.

The item is made of heavy and flimsy plastic. It is center heavy and does not stay in place as shown in the picture. It is differently not worth the $45. This product would have been better, if it was made from harder plastic. Good design, but bad quality.
