This is an open source community effort to develop a range of low-cost air quality monitoring and remediation tools. Welcome!

Join in by:

  • Reading about goals and asking great questions
  • Trying (and critiquing) our community-made how-to guides
  • Posting your own how-to guides and mods
  • Building on others’ work; hack and remix the kits to refine and expand them
  • Submit your improvements for inclusion in an upcoming starter kit release or add-on
  • Serving on a Research Review Group for a 3 month period


State-by-state info sheets on indoor air quality assistance and governance (work in progress!)


Activities should include a materials list, costs and a step-by-step guide to construction with photos. Learn what makes a good activity here.
