I've been doing some research into misting systems. I've had one that works off the garden hose with 10 mist nozzles and while is does spray water and drop the temp a little people do get very wet under them.
In my research I've found that if you get a 1000-1500 psi pump you end up with extremely fine water droplets that (apparently) vaporize and cool the air by up to 30 degrees. These things aren't cheap (cheapest I've found is ~$1000 for 10 nozzles) but if it helps cool down these 100 degree days I'd make an investment.
That said, does anyone have a high pressure (with a pump, not just off the hose) misting system? If so, how do you like it? Did you install yourself? Is it worth it and how often do you use it?
Thanks for any advice or opinions!
