Making a Corsi-Rosenthal box using computer fans (12-V 0.9A) that will serve as an economical air purifier that serves to reduce the risk of transmissions in classrooms. #COVIDisAirborne
@jcagar I still believe a network of such PC fan/filter fixtures within a space is compelling to explore (akin to lighting design). A factory roll of MERV-13 or MERV-14 can most economically/simply achieve a desired fan/filter surface area ratio through simple shapes and construction methods. Scale/array to achieve desired CADR. The question remains how performant such a design is compared an equivalent box filter. (I gave my supplies away in hopes of that answer.)
