Hello Lori Decker,
You may prefer ceiling fans for the space and air flow issue, as long as the ceilings are high enough and there is not the risk of equipment getting stuck or being flung back down. I would shy away from mist for the mold issue, since you are already dealing with sweat. Have you suggested a cold wet wrap around the wrist or neck for personal cooling?… that can do wonders. As long as no one is getting sick, warm rooms help the heat acclimation process for summer, anyway; maybe that will help the clients work through, also. Floor fans seem to only help the ones who are blocking the air flow.
Take care and stay cool; do you want winter back, already? 🙂 Where is the snow when we need it?

If possible, you want to be able to move air into and out of the room. The optimal arrangement would be to have the cleanest possible air moved into the workout area and the air from the room moved back out. Filtered air is most likely your best bet and there are fans that have air filters. If the air quality in your area is good, then bring air in from an outdoor source (hopefully your building has a air quality controlled ventalation system) and then use another fan to move air back out of the room. In room fans just circulate the air around the room and create cooling by evaporating sweat on the skin. Using a system to bring air in from a freaher source and move air across the room and back out to move the exhaled air (which contains moisture, odor and CO2) from the room is much more beneficial.
