A few days with this thing. Love it. With some slight modifications, made air guides from tape, upped the total output to 500ml/hour, +20% .
It was leaking alot of airflow on the two sides and top of the filter holder.
The unit is very open and easy to clean. The Ultrasonic had so many little crevices and places where the hand can't get into, this one is just 1 big tub.
No white dust everywhere this is hugely beneficial.
