Swamp cooler for home wall

How bad is the humidity created by a swamp cooler? Want to cool my home wall in my basement. Don’t really want to create a hole to pipe out the hot air from an air conditioner. But I’m also skeptical that a swamp cooler would make things better. Anyone have experience using one to cool a smaller room for their homewall?

If you don't have a vent for an AC, you probably don't want a swamp cooler. They need to be able to push air out of the space. If it's an enclosed room, your humidity level will just keep rising. You need a window for a vent. 

Also if you're in an area that's already humid (east coast of the US, etc), this will likely just make it feel more humid and not less cool. The drier the ambient air, the better a swamp cooler will work

Exactly all the things I was thinking.

As Sean said, you must have an exit point for existing air (as you're pushing "new" air, now moistened, into the room). Since it's a basement, do you have a window well, with a casement or slider window? If not, do you have a fan that exhausts to the exterior of the home? If the answer is no to either/both of these, and/or you don't live in an arid region, then sounds like a swamp cooler might not be the best way to go. 

They're absolutely lovely with 2-3 windows cracked 1/4-1/2" around your home, but installing a full swamp cooler for a single basement room seems like a lot. How about just purchase a big industrial fan and plug it in to the wall outlet???

no windows in the room unfortunately. I was looking at the mini swamp coolers on Amazon that don’t have any exhaust tubing. I am in a very arid region, but the humidity buildup in a small room sounds counterproductive. If I do cut a hole for exhaust, it’ll be for an ac unit I think.

Thanks all for the feedback.

DIY minisplit/heat pump. Claim federal tax credit, too. 

I made a DIY redneck swamp cooler with a plastic tub, an aquarium pump, some PVC tubing, and a box fan and a swamp cooler pad. It works best alongside AC as AC also dries the air in addition to cooling it, but the swamp cooler on its own cools the air by 5-10 degrees Fahrenheit. If it would otherwise be 85 or 90 degrees in the house, that's a massive difference. I'm going to build a nicer one for next Summer that's made of wood and doesn't look like a complete hobjob, but I live in a fixer upper single wide trailer, so it rather fits the ambiance. Hopefully the fixer upper will be fixed up enough by next year where the nice swamp cooler also better fits the ambiance. =)

Happy to send you deets on the redneck swamp cooler if you want, but it's really not hard to figure out. Works great. Do recommend. Not sure about these "mini swamp coolers" on Amazon. You need a large surface area for them to be effective. I would be surprised if they were more effective than the redneck swamp cooler you can build for ~$50.
