I bought a humidifier at Walmart for twice as much as these. I am going to order them promptly. I know they work because of where I live, in a very arid desert. If you live anywhere near water, even lakes like where I used to live in Kansas, these will not work. Since they run on moisture and cool accordingly, but if you live where it is high humidity and dew point, NO, they will not work. Out here most people have swamp coolers (maxi humidifiers) and only use A/C during Monsoon season.
New Orleans, Miami, California, WOW. Nope, not for you.
Bottom Line: Yes, I would recommend this to a friend
