That way, the fan is forcing the same amount of air through a greater number of “pores,” easing the load on the motor. That design costs less than $20, assuming you already have a fan and some tape.īut forcing air through just one filter could put a fair amount of strain on the typical fan - especially if you run it for hours at a time, said Meyer, the Hive76 president.īetter to increase the surface area through which the air travels by building a box of five filters, said Jim Rosenthal, past president of the National Air Filtration Association and chief executive officer of Tex-Air Filters, a filter manufacturer in Texas.

Here’s how to remove particles from the air with the flick of a switch.Īn easy approach tried by some do-it-yourselfers is simply to slap one filter onto a window fan, attaching it with big rubber bands and sealing the edges with duct tape. Centers for Disease Control and Prevention to acknowledge that COVID-19 can be spread by airborne particles - those that remain aloft for a while, rather than settling within six feet - the agency updated its guidance to reflect that evidence this month. Months after scientists called for the U.S. “This is definitely better than nothing,” he said. Waring, who has been following the online discussions, agrees. But if done right, it is a reasonable approach for removing some potentially virus-laden particles from the air, according to air-quality scientists who have been batting around various designs on Twitter.ĭrexel engineering professor Michael S. We can’t guarantee that this contraption will stop you from getting sick. All you need is a window fan, some duct tape, and five of those pleated, cardboard-framed filters that are designed for home forced-air heating systems, as we explain in step-by-step instructions below. (He is a biomedical engineer by trade, so who was I to take charge?)īut, really, it was pretty easy.
I helped hold things while Hive76 president Tom Meyer did most of the work. I built one this month at Hive76, a “maker space” - a member-owned workshop and tinkerer’s paradise, located in a former factory building in Kensington.
