Just a thought—I’ve been cleaning houses for a living 27 yrs now. When the humidity is above 70% I notice trouble in all aspects of the job. Nothing will dry without smearing, mold starts to grow, smells that usually are not there become noticeable. In general, humidity makes people sick (inside the home). Noticed this throughout my so-called career. I have a de-humidifier in my basement and empty it everyday. After it gets below 60 degrees(yes I’m a cave woman don’t know celsius) I turn it off.
Get one of these, they are marvellous. We’ve had one for years.
