How to make an Evaporative Air Cooler out of a Box Fan! Evap./swamp coolers are great for dry climates. step by step instructions will show you how to do it. can drop temperatures up to 30F. for added cooling use ice/cold water. can be solar powered. note: the fan can still be used like a regular fan even after the conversion. the cooling pad is very porous and has almost no effect on the fan motor or the volume of air that flows through the fan. Note: To see video of my latest "box fan" design, visit my youtube channel video page and look for "Homemade Evaporative Cooler! - "whole room" Super Cooler! - up to 30F drop! - Easy DIY"

i tried this a few summers ago. this is a great vid. gave me some ideas to finish this. note: some ppl say dont use swamp coolers in humid climes . when my dad was a young boy on his farm in ohio usa, ohio can get very hot and humid, he would soak a sheet and cover the window and put a fan on it . instant cool. thanks

Ha ha. We used to drive to CA from AZ in the 1960's during the night and use water soaked anything in front of a partially open window. IT WORKED better than nothing. Alternatively, we would roll up all the windows until we were dripping in sweat, then roll them all down and for a few minutes, we were cool! That's natural swamp cooling at its finest....

thanks. the plastic window planter box is a great idea (even if you don't recirculate). you could elevate the fan maybe 6" off floor and then slip the planter box directly beneath the bottom of cooler pad to catch the residual water.

I've seen a lot of these things but this one by far looks the most promising for good results, great video man :)

Very cool. Great idea!
@tomlovin8931 8 years ago

This is great for low humidity places like Arizona. The water in the pad pulls the heat out of the air coming in. The air comes in moist and cool. You could cool a big room and more just with this.
