I too use the Dri-Z-Air product. I use it in both my RV and my boat. 1 in front cabin of RV and one in the bedroom. I open all the cabinet doors, drawers, closets etc. so that I get circulation.
Personally, I swear by the product. One thing though, is to check on it a couple of times over the winter. The storage pot at the bottom can fill over the winter (depending on weather) and the liquid is very caustic. I put the whole assembly in a plastic bucket. This insures never an accident from overflow and gives me something to carry it out of the RV so I don't spill it.
