Exposure to air pollution, whether its coming from outside or inside the house, can be very unhealthy. Participants in the ROCIS Low Cost Monitoring Project measure the levels of small particles, radon, carbon dioxide, carbon monoxide and more in their homes and explore possible improvements to indoor air quality through virtual sessions. Anyone interested in joining the LCMP should attend one of our upcoming intro webinars, April 4 at 7 p.m. or April 5 at 10:30 a.m.—attendees can decide whether to join the cohort following the webinar. The cohort sessions run April 18 to May 17.
