I ordered stuff off amazon to make my own. I dont like the hose one doesnt cool mine down enough.
evaporation of water only cools the air down about 20 degrees.... The finer the mist the better the job. the way to get fine mist is to have High pressure nozzels. Not cheap.
Ideally Water comes out of the house at about 60psi.... Good enough to wash your hair in the shower.... will blow the heads off the low pressure nozzles. But then you have nmy case where I had to put a pressure regulator on the water main.... because the pressure was turning my inside faucets ON... jsut a drip or two.... At the time I had 80 psi coming out.
Here are some Answers to how this all works. Yep they are trying to sell you stuff but the FAQ is good.
