I’m a filmmaker, jogger, and environmental/climate/air quality advocate living in Pittsburgh who is enthralled by the prospect of “seeing the air.” I’ve been dabbling with low-cost monitors for years, but those efforts were boosted by a strong air quality community empowered by low-cost monitors like the PurpleAir PA-II and PA-I. My latest film project examines (major) air pollution issues in and around Pittsburgh, and you can read about it and see the trailer here: https://inversiondoc.com/ . The rest of my work can be found at http://lens.blue/about/ . I’m always willing to geek out about all things air monitors. Feel free to reach out if you’re so inclined!
