If Twitter goes down soon, I might as well post the tabletop box. It still needs little feet (there is a filter below, so 2 complete 16x2). My nicest box yet.
It goes to the center of the table, separating both sides. It will be paired with a large flat box above the table. Build pictures. White cardboard structure, Anaglypta relief wallpaper, black paint. The box can also be used standing on a small side.

We are clearly in this for the long run. Air filters will be there for a while. Why not try to integrate them in the furniture ? Inspi @ee_kelsey
A Starkvind is a perfect fit below a Raskog trolley for a single filter box with a plenum. You could even use the pretty bamboo top. Starkvind fit tightly in the large side of the cheap triangular Vesken shelves (<10€). Block the other sides with fans in cardboard using tape: you have a filter shelf.
With a bit of coaxing, you can convince a Starvind to fit in a narrow Billy. #ikeahacks #CorsiRosenthalBox

Getting somewhere for elastomeric respirator style ! #steampunk vibe but P3 protection based on GVS Elipse P3. Now the right color elastics. Thanks to @nickelpin
for inspiration, paint advice. Angelus paint and finish, Games W. acrylics for deco. #Elastomeric, #respirator A short description of the process. You can find a few pictures here, but I had some trial and error process and even with the final ones, no warranty it will hold long, as @nickelpin also explained very well !
