What does everyone do to help reduce dust getting in your cabinets? I have gone as far as using rubber stripping on the seams of the doors in the past and still use them in the dry months of the desert northwest. This little thing though has made a big difference in one cabinet I have tested it in for the last 3-4 months and it is only about 8 inches tall. About the time I determined it was effective Amazon was out of stock on them but they finally came back into stock today so I ordered 3 more for my other displays. It is the only one I could find that was this size and plugged into a AC outlet.
