Shortly after I made the first submission video, I had come down with a cough. This progressed for a week and I hacked up lots of white phlem. Bad sign. Given that I didn't have any other symptoms like a cold or flu would give, It seems much like acute bronchitis due to inhalation of particulate matter. I should have known better than to not use a respirator during the extreme tests. I lucked out and my lung function returned to normal after one week but it was definitely not a fun experience and now I'm anxious of possible long term effects.

The problem in designing and building a homemade wet scrubber is that there is a high chance it doesn't work the first time or as well as you want it to and in this case it gave a false sense of security when sucking up smoke and other shop dusts. My wet scrubber showed results that it could filter down to 2um particle range showing penetration for particles of 1um and below. Sub-micron particulates, namely smoke, was definitely penetrating the filter and I'm sure super fine shop dust got through. I experienced it in a terrible way, unfiltered. I'm praying the dust I inhaled isn't silicon or something else toxic. Also no wet scrubber alone will scrub out VOC's (which is a gas, not a particle) less that VOC is liquid soluble and any combustion product will contain a cocktail of harmful VOC's.

So if you the reader plans to build one of these please please please always use a respirator when testing until you can determine for sure the scrubber is working properly and also do not use the device beyond its cabability. Don't let this device give a false sense of security like I did. Consider yourself warned.
