Product review (4 stars): Works well but doesn't last the winter
These wicks only last as long as the amount of calcium in your local water.
I live in Toronto and they last five to six weeks before the unit becomes
to inefficient. I have two evaporators, so I need six wicks per winter. The Amazon
price is the lowest I have found. I love the evaporator because it's the quietest humidification
without the white powder dust the eventually comes from all the sonic units, even the Air-o-Swiss
models.
