Mains Dehumidifier Q

I have a small-ish mains dehumidifier about the size of a large vacuum cleaner.
It has a tank with a float cut off when full, or it can run with a drain pipe, so either way it can be left on.
Works very well.
Used it in the bus before I got a tent-type garage but haven’t really needed it in there since.
Also used it in the wooden garage and cabin in wet winters from time to time just to stop damp building up too much.

Only downside is when temp is in low single figures it can frost up on the intake filter.
