Homemade Evap./Swamp Air Cooler - DIY AC (air cooler) - Low tech. Very Effective!

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).

You saved my life - moved into a manufactured home and the a/c system is still being worked on and the heat hit Las Vegas earlier than it should have!!! Life saver!!!

It's 100 plus now. My AC unit broke and this DIY cooler hack saved the day!

[gundog]

That's old school effective. I've been to countries where they put long bolts of cloth in towers with open/ ventilated tops that pushed the cool air into the structure and allowed for hot air to escape. Been doing it for thousands of years and it still works. Cheers

Great idea!
Could dry your laundry this way too, and you'd be multi-tasking :)

Our friends in Europe could really use this tutorial right now. :)

WOW! We don't have many hot days in the west coast of Canada so most of the buildings don't come with AC, although recently we've been hit with many bad heat waves, last year we had ~700 people die from a sudden record-breaking 49.6C (121F) heat dome, and this year we're having one of the longest stretch of hot weathers. I'm so lucky to come across your video, this literally can save lives. Thank you so much for sharing!

Wow! Fantastic. Our A/C went out the height of the day in Phoenix. A cool 106! Was ready to hit friends or a hotel. But decided to give this a try. A fan, a couple of wet towels, and a foldable double-wide bed frame. Working like a charm. After watching a couple episodes of Survivorman last week, this ain't nothing. LOL. Gonna rough it out!! Thanks so much for sharing!!

This is awesome! I just did this with some laundry and I wondered if anyone else had done this. Such a great idea, after the laundry is dry I think I'm going to wet some towels like you did!

Heck of a lot easier than diy'ing something, especially in the UK where it's only unbearable for a few weeks or so. Many thanks!

Saw this on Reddit and sent it on to friends in the UK right now. Thanks!

This evap method is great for killing stale heat in a room, all you need is to place one unit at higher elevation at least overnight and it works just as good as a cheap air conditioner. I didn't have much props to hold the cloth so on mine I just wrapped the fan with 2 wet boxing handwraps, and left space at the bottom of the fan for the cold air to sink. Getting a thermostat to benchmark the results too but already noticing the difference after leaving it running overnight.

You sir. Have just saved my life. I have my hat off to you. I just did this. And it's pretty amazing.

I was wondering if this sort of arrangement would help humidify a greenhouse and keep the temperature in check. Thanks to you I have the answer without doing the experiment. Very useful.

This would work soo much longer, and with less upkeep, if one end of those towels was resting in a bin of water, as it will naturally wick along the fibers, keeping it wet as long as the bin has water in it.
Cotton and nylon are the best for wicking water.

Thanks! All stuff I have in this room with me, already. Better than when I tried the fan over a hole in an ice chest lid and the fan almost fell in, while plugged in.

[Galvaxatron]

This is an amazing trick.
Alas it is way too humid where I live for this to work.

[tailwind]

cool. i lived in the philippines and that is how we did the "AC" hook up.

[Morcaiden]

I'll try it if ever gets that warm. We've had a cool summer, which is odd. Might end up with a summery autumn.

[jojocrater]

This is genius, thank you for sharing ❤️

I usually just drape the towel over the back of the fan with a bowl or container of water sitting on the floor and towel dipped in to keep it going for longer. It also works better when more of the air is being drawn through the towel.
