Product review (4 stars): Hints to prevent spills
This indoor dryer vent says to add water to the bottom for humidification, but the vibrations of the dryer and the vent "hose" causes it to fall over and spill. As a remedy, I put 2 full size kitchen sponges (antibacterial) into the bottom and wet them with the water and it works just fine! The mass of the sponges keeps it from falling over, but if it does the sponges prevent water spills. It humidifies quite nicely as well. I re wet the sponges (with a funnel) as they dry out
