I pulled this information together because I was curious to see what was available after hearing that my employer is giving thought to masks or hoods for its employees. What surprised me is that the "good" stuff all seems to be between $150 and $200 and higher. What didn't surprise me, but was remarkable, was the wide variety of hoods on the market. Some are good, others are not, I suspect. I leave to others who know better to opine on the relative merits of each. I suspect a good part of the price is that that is what the going rate for clean air is in a time of crisis.

My opinion only. I would add something said many times before on this forum: equipment alone won't save you; training and mindset are critical to survival.
