HEPA filter, old/new.

When I’m thinking about good (somewhere between low- and high) #tech, I’m also thinking HEPA. Randomly fabricated fibers that randomise and trick the movements of particles.

Air purifiers are part of the #solarpunk future. Not only to be equipped for #wildwires. #airpollution

*Edit: great typo: #wildwires instead of #wildfires!
