What GMO said, but you'll likely need other mitigation steps. I've found that reducing the temperature during wash (if you use CIP this should be relatively easy). Most people think higher temperature is always better, but that really isn't the case. In some cases higher temperature hurts your cleaning effectiveness, and many cases you just waste the energy to get it that hot without helping the cleaning efficiency.
So...do what you can to reduce water and temperature. As for dehumidifying if your ventilation isn't set up well, and the filtering ability you may be best off using a dehumidifier in the area to knock the down humidity. If your capital budget, or if you can get buy in, see if the ventilation system can be upgraded in that area. It could be something as small or simple as a larger blower motor for the HVAC. Just keep in mind you don't want it recontaminating your cleaned surfaces so filtration is key.
