Michael Feldstein, a former disaster-restoration pro who founded air scrubber company Jasper, talks with Chris Williamson about why indoor air quality is becoming a top health concern. He traces his path from mold and wildfire cleanups, where cheap purifiers failed to stop recontamination, to building a quiet, good-looking scrubber.
Key claims: indoor air is five to ten times dirtier than outdoor air; CO2 above 1,000 ppm brings brain fog; a 150-person community test found 25 more minutes of sleep and 18% deeper sleep. Culprits include shoes, cooking, fragrances, candles and diaper pails. Free fixes, home-buying cautions, mold-testing nuance and Jasper's school and workplace studies round it out.
