Do you have a lot of undesired moisture in your house? Maybe in your bathroom, toilet, living room or bedroom, for example? Why not put a humid absorber in every room! The humid absorber extracts the moisture in the room and collects it in the container. When the humid absorber is empty and the container is full of water, you can empty the container and put a refill bag in the humid absorber container. A refill lasts about 1-3 months. This Starter Set contains a tray with 12 refills. This will last you for a long time!
