North­ern California’s now infa­mous Camp Fire was not only the largest, longest, and dead­liest wild­fire in the state’s his­to­ry, it also pro­duced record amounts of smoke. Schools closed, there was a run on pro­tec­tive masks, and peo­ple were fash­ion­ing do-it-your­self air puri­fiers because there were none left in stores. And it looks like we will only see an accel­er­a­tion of wild­fires in the future. This grim fore­cast has brought a surge in traf­fic to web­sites that mon­i­tor air qual­i­ty like AirNow, Weath­er Under­ground, and Pur­pleAir. This week on Sea Change Radio, we speak with the founder and CEO of Pur­pleAir, a com­pa­ny that sells laser air qual­i­ty sen­sors for home use at a rea­son­able price, and posts all the results in real-time on its site. We dis­cuss PurpleAir’s busi­ness mod­el, its unique brand of crowd-sourc­ing tech­nol­o­gy, and exam­ine the ways that it casts the world in a dif­fer­ent, and some­times fright­en­ing, light.
