Ventless dryers aren't as good as vented. Takes longer to finish a load. In your kind of house, I bet your hose in just sticking out a window or in a sink?
Ventless heat pump dryers are the most energy-efficient option, using up to 70% less energyI wash
then i use dryer for just 30min
then i throw it on the clothesline when its hot and still a bit wet
dries in 4hours
This method also makes your clothes last 3 times longer
