So I got an advertisement in my inbox to day that was so very misleading I felt compelled to write this post. It has to do with these little boxes being marketed as portable air conditioners. This is reminiscent of that device that claimed to be able to see thru walls.
There is a video on youtube that explains it way better than I can
Now to be fair, these units actually DO work . . . kinda sorta. but they cool the same as any humidifier. The science is, when water evaporates it takes some heat with it . . . but not all that much, and if the air is already high humidity, no water will be removed by evaporation, hence, no heat will be removed.
It amazes me that this kind of thing can be marketed legally, making such outrageous claims. Don’t be a sucker.
Main thing you can do to keep cooler is to CLEAN THE AIR FILTER in your regular real AC units. – JL
