Zippy I'm not sure there is a good way around your filtering problem. The more you filter and seal around your cooler, the hard its fan/motor have to work and the less efficient it becomes. The wet media will naturally filter dust out of the air that enters your yurt, but the pads are the filter and will fill up with dust regardless. I will be using my DIY trashcan cooler and just plan to only run it when the wind and dust are at a minimum. I also plan on wrapping the cooler up with something when not in use to prevent excess dust from lining the media.
