Large Area Evap. Air Cooler! - DIY AC Air Cooler! - Simple "Box Fan" Conversion - works great!!

We live in Arizona...... Perfect solution for my small insulated garage/workshop..... Humidity averages between 2% and 15%..... these swamp coolers will not work in a humid environment but are fantastic in dry places like AZ

Built these overseas while stationed in hot climates. Works very well. Nice vid!

This design works! in desert areas, this adds moisture to the area making the blown air feel cooler.

These were called "swamp coolers" back in the day. I never thought about trying to build one. Awesome idea. Thanks for sharing. I'm going to try this.

PVC piping... a gift from the Gods.

Great job. I have seen a number of this type of swamp cooler being made but yours is probably the cleanest and easiest of the bunch.

Everyone keeps saying "add ice" but it would melt in a matter of minutes. I know because I'm from Arizona and very familiar with the "swamp cooler" idea, and have had many in the past. This really looks like an easy build and although I now live in a house with an $8000 A/C unit, I still prefer swamp coolers. Right now humidity is up in Arizona so swamp coolers aren't effective, but I may consider this for my bedroom at night beginning in mid September when it dries out again.

It's too bad how A/C has taken over swamp coolers in Arizona, but I always hear the same reasons: A/C units have become much more efficient, the air outside is dirty and not healthy anymore to breath, A/C units require less maintenance. I still think the feel of moist air is so much nicer than the artificial chill of A/C units.

Love your idea! My house is literally under trees and it stays cool all the time! People grow more trees! That helps stops global warming!

this will be perfect using big ice cooler from thrift store instead of storage container because you can put ice and water without moist coming out

We use to cool our entire house with a full size roof swamp cooler. That was in northern California where the air was fairly dry most of the year. Once the rice patty farmers flooded their fields, the humidity was too high for the swamp cooler to be very effective. Most people don't realize swamp coolers in dry climets will reduce the air temp indoors by up to 20 degrees for a fraction of the cost of AC units. Plus the humid air causes dust to drop to the floor, keeping the air cleaner and the house much more dust free. The best way to use a swamp cooler is to pull dry air from outside from a window or in our case the swamp cooler was on the roof, and crack a window at the other end of the house which pushes the hotter humidified air out of the house. I had a similar roof mounted unit in Las Vegas. It kept the mobile home I was renting at 76 to 78 degrees while outside it was 98+.

I've been suffering all summer with air conditioning issues so I'm gonna do this when I get BK from my trip to help ty so much this is awesome

Update to my previous comments: I built this using 1/2" PVC that was on hand and an 18-gal Rubbermaid container i had. I used a 6" desk fan (on sale), a water cooler pump from Wal Mart, $14.88, a water cooler pad and a half hour before I go to bed, I add 2 blue ice and 2 pro pak "freezies" to the water. 10 min later, I turn the cooler on. The pump and fan are plugged in to an extension cord because the unit is on the far side of my RV bedroom. The fan has a three-prong plug, which is plugged into an adapter (dollar general), then into the ext. cord. 2 nights ago, I recorded 90 degrees inside the bedroom at bedtime. 1/2 hr after turning the cooler on, it was 80 degrees- comfy and sleep-able. I now need to get a timer so it's not too cold when the outside temp drops. Where am I? I'm in the Four Corners area of New Mexico, near Farmington. This thing does work- my total expense has been around $30. If I bought everything new, it would be around $50, still less than half of a commercial water cooler/evaporative cooler. Thank you again for this design- it's a lifesaver!

I'm sitting next to one of those now :)

Try ice blocks or icy water, makes a whole lot of difference.

Wow nice. Thanks for sharing. Im living in a country with humid and hot weather.

Very clever!!!!! Thanks for the info!

I bought a few of the things I needed to make this last summer and finally built it today! seems to actually be working

I gotta build one for my fifth wheel. It should work well here in NM.

And don't forget to open windows on the end of the house, to allow the air to move completely through.

Wowee, I think this model looks easiest for me to put together. TY!

Love it! Swamp coolers have been around for a long time. Nice to see a DIY version of one.
