We spend 90% of our time indoors and the air in most of our homes contains formaldehyde. Formaldehyde exposure can worsen health. This app works with color-changing badges to allow users to measure their indoor formaldehyde exposure. The app provides information on recommended formaldehyde levels and tips on reducing exposure if the concentration is high. Users will also be given the option to upload their results and complete a survey to create a national database of formaldehyde levels. The survey will ask about housing characteristics and also include the option to report health symptoms.

We are currently looking for interested individuals to beta test our app! Please click on “Beta Test” above if you want to help us out.  We would love your feedback.

Creation of this app was funded by National Science Foundation (NSF) grant 1645048. This app was created by the authors and has not been reviewed by NSF.
