In the PDF they say that if the filter gets too hot it becomes impermeable to water. So I guess if the steam is too hot it wouldn't work.
On the other hand, if you just let any aqueous solution sit for a while in a container sealed with the filter on top, you get a stronger solution over time. They say they tried it with booze and yes, it works. Useful if your end product will evaporate quicker than water.
Cool... but will they find actress with a fine enough ass to play Jenna?
