We did try that. Didn't do much for us. Thinking back to my high school chemistry teacher (back when dinosaurs roamed the earth, according to my kids), one of his favorite mantras was "like dissolves like". Seemed like tomorrow's fuel would be the kitten's meow for cleaning the gas. Didn't do much for us. But maybe somebody else can make it work. Our coarse dry filter material (stuffed into a piped steel drum) is just cheap insulation, unfaced batting, R13 I think. Our new wet filter is right before that (and right after the heat exchanger). Really all embarrassingly low tech but very cheap stuff and seems to be working for us.
