Wildfire Safety Research: An Evaluation of DIY Air Filtration
CIRI
The Chemical Insights Research Institute of Underwriters Laboratories, with the support of the Office of Research and Development at the U.S. Environmental Protection Agency conducted a study assessing the potential fire risks of operating DIY air cleaners. Specifically, this study evaluated the risks of fan overheating and potential fire ignition resulting from different fan/filter test scenarios. Five different electric box fan models (approximately 20"x20" in size) were tested with a filter attached to the back side of each fan.
