If you get the same one I did for around 15.00 or so, it comes with a set of replacement nozzles. None of mine have clogged yet though.
You just hook it to a garden hose, and turn the flow down low. The hose will build pressure to keep them going once it is set correctly. They do bleed air very slowly though, so pre bleed the hose before connecting it. I Just kink the hose and connect it.
oops, it's a bit higher now, but this is very close if not the same thing. mine is longer than 10 feet, but I reckon they are just claiming the space of misters

They are meant to be strung in line with each other so you need to find a tiny rubber plug for the nipple on the end. If you have a vacuum plug set it's in there.
It honestly does cool the air for about 20 feet out and about 12 feet wide with the aid of the forced air. about 3-6 feet away it will develop a damp area on the floor, so it does have to be positioned for the best results. Still, all last weekend I had it running on Betty's Hiney with a patio umbrella. The heat was no concern. I turned it off when the sun went behind the trees every night of course.
Tip , obvious but nevertheless I might caution, make sure the fan is turned on before misting. Otherwise mist will go into your fan. For them to work real good I have the misters set at about a 90 degree angle to the air flow. They would spray into the fan if it was off.
