I used this it only to not only filter the air coming into my pass through storage on my RV, but to also block the rain and road grime from coming in. I cut thin plastic squares to seal the open when not in use during travel.

Perfect to be able to cool the pass through when my inverter is running hot!

Super fast shipping, easy to assemble. The filter is easy to clean. I'm an idiot and didn't realize adding the grill would add so much thickness to my fans, making it so not all the fans can fit on the radiator. That's my fault though, I shouldve realized. Great product.

I have an entertainment cabinet with glass doors and multiple media devices (DVR, Surround sound, Xbox, Blueray player) and the cabinet would get quite hot when using the electronics within. I purchased these fans with a thermal controller and they work great. Very quiet and they come on automatically when the temperature gets around 80 degrees. The price was good and the product looks professional after installation.
