i have heard about that. and some of the extractors they sell on ebay actually come with a metal type of mesh screen. coffee filters are Great! however, i know there is something a lot better then a bleached white paper filter. and to the person who said im making this hard on myself, im not! in fact if you would have read my post fully you would know i have used coffee filters before, and have been making this stuff for years. i just would like a census on whats the best and what do most people use. if everyone that posted a reply would have given more then a sentence or 2 then maybe your reply would have a little bit of merit. but frankly, if you have made BHO 100 times and used a coffee filter 100 times, i don't think you could help me. i personally think input from someone who has more info, and more experiences is what im looking for. im looking for someone who has made BHO 100 times, but 10 times this way and 10 times this way. i would really like to stir up a conversation with someone who has experience with making the stuff many different ways, many different times. no offence, just what im looking for. so please don't be offended. im a very in depth person, and 1 way is not necessarily the best way.
