Homemade Evap./Swamp Air Cooler . easy DIY. made using only a fan, towels and a drying rack. very low tech and very effective. dropped 82F air (with relative humidity 8%) down to 59F. dropped overall air temp. in room down about 13 degrees. for more cooling – use more towels. works best in dry climates. the drier it is the better it works. can be used daily or great in an emergency (as many people will already have everything needed). note: can also be used to add humidity to the air (in winter for example, when it can get very dry).
