Will filtering oil help reduce the dirty smoke from my drip system? I climbed up on the roof to install a chimney cap and there is a ridiculous amount of soot in my chimney, I could have grabbed a handfull of it! It is light and fluffy kind of like the soot from when you start an acetylene torch with no oxygen. hopefully someone else encountered this, i realize drip systems arent popular around here but I am on a quest to pefect this one, lol!
