Good point. A coffee filter and a #1 lab filter are in the same micron range at 15 to 25..Regular coffee filters for me.

Really, I never had any luck with those little water flow vacuum valves? Was always able to pull a better vac just using my mouth and plugging with tongue. Maybe you're talking of something different. If so, I want one! I'm loving my new 2 stage 5 CFM.You can pull -28.5" Hg vacuum using a faucet aspirator pump to save money on the pump part.
-28.5" Hg is usually low enough for vacuum filtration, but not for evacuating a chamber prior to BHO extraction or post-extraction purging.Really, I never had any luck with those little water flow vacuum valves?
