Recommendations for mist cooling system for deck?

It's hot on the deck, even at night. Anything to look for/look out for with a mist system for cooling? I'm in Japan, but we seem to have similar products as what I see on Amazon US.

One type is a bar, maybe 3-4 feet long, mounted on a tripod. Height adjustable. The other main type is the 10-20 feet of hose with nozzles that I could mount around the perimeter.

What I like about the tripod type is that I could move it according to need, including breeze direction.

Advice appreciated.

People on some of the FB Ryobi groups are really enjoying these. We have a ton of Ryobi batteries and it would make good sense for us but in the hot muggy East I doubt it would do any good.

Those misting systems (evaporative cooling) only work in places where the relative humidity is low.

Hope you and yours are holding up OK in that heat, Drew. 100 forecast for Friday. Stay cool!

No kidding, we had our misters on (it’s hot and humid right now), it helped a wee bit, but the yard looked foggy.

Thanks lost in space. Yeah, around 100F every day and never below 80F, even in the middle of the night. Worst part is humidity, 65-85% every day.

The high humidity makes me wonder about the misting system, as freeradical noted that they don't work so well in high humidity.

On the other hand, I've seen misters in public places and they seem to work. They certainly feel good. Though maybe because it's a larger open space and kind of an industrial style setup.

The key (as I understand it) for misters to work effectively in humid environments, is that they need to be very high pressure. Last time I researched the market, none of the retail machines were very effective. You need the very high dollar commercial models.

The reason for the higher pressure is that it atomizes the water into smaller/finer droplets, making it easier to evaporate into the surrounding air (and in the process of evaporation, cool it).

We have a hose/brass nozzle system and while it definitely works very well, there are certainly some drawbacks.

It puts out quite a bit of water and makes our whole deck area pretty wet.
If the nozzles are aiming up into an arbor or spraying toward any close by surface it makes water drip in pretty concentrated areas.
If there is any breeze at all it redirects it all over the place and rarely is it exactly where you want it.
And of course it’s not mobile if it’s fixed to a structure like a pergola or something.

I think a mobile floor or slightly above flood level type unit like the one linked above might be more effective.

That said, I have been parking a deck chair under ours daily just to get through these back to back 100 degree days in Northern California. It has been a savior!

We have a 1000psi system brass nozzle with stainless steel tubes. I’m trying to upload the damn picture on here. But file needs to be jpg not jpeg. Frustrating

I bought an inexpensive misting system off Amazon and it worked well for a year. Then we moved to a new house where I tried it again and it worked well for a year but then failed. I replaced it with a higher quality misting system with brass misters but it also plugged. After that I replaced the brass pieces and put a in-line filter in place and that seems to have solve the problem.

Just manually change the file name extension from jpeg to jpg and you'll be fine.

No, the mist wouldn’t be fine enough.
