Thanks for the suggestion. two years ago the apartment above us broke a pipe during the cold winter, it ruined the lower basement apartment where I live. the restoration company fixed the place up, but less than 2 weeks after moving back in i noticed the smell. i informed the land owner of the problem but she ignored it saying the same thing as yourself get a bigger dehumidifier.
the dehumidifier i use can dry out our bathroom (after a shower) in less than hour, from 50%+ humidity to 30% normally i empty the tray after a long shower. our extractor fan in there is also quite good. but I wanted to test how well the dehumidifier would work. and was not surprised by the effectivness considering its strength.
in the slightly larger salon / sitting room, where i have my TV, and soft ( the problem area) its just a little under double the size of the bathroom. I use a powerful floor standing fan to help force extra air towards the dehumidifier, creating a kind of circle of air flow in the room. so the exhaust of dehumidifier blows clockwise around the room, the fan is on the other side continuing the flow of air back towards the dehumidifier.
I know for sure the restoration team did not treat the floor properly. but I informed the land owner who did nothing about it. so I feel when I leave it will be their problem.
But until then, its my problem. I was thinking of attaching a funnel like whats on a clothing dryer to the exhaust of my dehumidifier and just taping it to the hole in the floor where my electric heater is. but i'm not sure how effective this will be at airing out under the floor.
