I got this to use in my camper. Right now we are living in it, so the warm air from the heater, creates condensation on the skylight metal since it is so cold.
Moisture is dangerous to campers since they are usually built for lightweight functionality, not built for year round use with more durable materials.
This helps draw all the moisture from the air so it minimizes the condensation on the door and skylights.
It has an auto shut off feature so you can run it and use it twenty four seven. It will shut off on its own when it is full. so you have then chance to empty the collection bucket.
It is working as intended and is heping save our camper so I am happy with this purchase and I woud buy it again.
