This is the new (beta) Inline Rich Wikis system. Use the "pencil" buttons after different paragraphs to edit inline, and report problems here

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

Resources

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


Activities

Add an activity  or request an activity guide you don't see listed

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