I am accumulating info on building a fume hood .
But in my searching , I am not finding anything about filtering / cleaning the exhaust ?
I did think of an idea for my vacuum pump , maybe I could do the same with fume hood exhaust ?
With the vacuum pump [ pulling a vacuum on gassing filter flasks , etc. ] running vacuum hose through a sealed water container - gases enter submerged tube going into water capture & vacuum pump a 2nd tube above water level out to pump .
With the idea of not harming the pump with refining gases , I did get a very good deal on a chem-lab vacuum pump , any suggestions welcome .
So the same with filtering fume hood exhaust - push through water to help clean up what the fume hood is putting out ?
It is going to be some time in the future before i have space for harsher chemistry , at this time working outside & limiting chemicals to hydrogen peroxide & hydrochloric acid , melting into buttons .
This is mainly for electronics gold & silver recovery [ I do on occasion get other sources of gold & silver ] , but no refining until I can setup a safe lab with a fume hood .
