Planet Detroit: Wildfire smoke is back in Detroit. A cheap, DIY air purifier can help
As Canadian wildfire smoke returns to Detroit, a simple $40 DIY air purifier made from a box fan and furnace filter can help protect your lungs. Here’s how to build one. A well-built homemade air filter will noticeably improve the air quality in a room, though not quite as much as a store-bought machine with a finer HEPA filter, explains University of Michigan School of Public Health professor emeritus Stuart Batterman to Planet Detroit
A homemade air filter takes 10 minutes to construct and uses materials that can be found at most hardware stores if you don’t already have them at home.
