Thank you for this video. The Dyson DC1100 Pro he recommends for air quality monitoring has changed my shop routine. My 1500 particle count of airborne particles 0.5 microns and larger proved that my air quality was poor. 3000+ is considered very poor. When I used my shop vac to clean up after a cut, particle count jumped up to over 50,000. After cutting one piece of wood, it jumped up to over 5,000. If nothing else, I have learned that my shop is dirty, I have to clean it up, then I need to figure out how to create ventilation better than what I thought.
Maybe a worthy final act for an old guy with lungs ruined largely by breathing wood dust for 45 years would be to edit Bill Pentz's text and reformat it into columns for a better internet experience. There's no doubt Bill is a giant in understanding this aspect of industrial health. His insights are the hard-won products of rigorous and tenacious investigation. The man deserves some award that does not presently exist. Read him in small doses if you must but, above all else, understand what he has learned and has attempted to share with us.
Yes, but not all woodworkers live in a climate or neighborhood where outdoor machining is possible and many of us are living the most common hobbyists's dream, spending more than 40 hours a week in the shop.
I"m tired of all you guys getting free shit from these companies,then not really giving a fair review. For people that have to spend $2-4 grand on a system and if it sucks try to sell it and explain why and not lose your ass. So how about show it in action and that it actually does what the sales and Bill Pentz says it does. Thank You
Your objections seem justified to me. I'd like to see air quality analysis both before and after the Clear Vue installation. My understanding of the situation is that any tiny particles are hazardous and no system gets them all. Further, ardent hobbyists and full time woodworkers may find cumulative lung damage a matter of life and death. Cumulative is the operative word here though I used to mock wood dust warnings saying, "Oh, yeah, a whiff of sawdust is another thing that will kill you." Statistically speaking, my understanding now is that there is no entirely safe level of exposure. The question becomes how much safety can you afford.
My conclusion from reading through Pentz's website was that woodworking indoors is simply not safe. Dust collection at the port does not get all the dust - do you have a hood over every machine? - and sub-5 micron particles continue to be a danger on the floor, on your clothes, etc. Pentz seems to me to conclude that all woodworking should be done outside and while wearing a respirator. Very depressing!
