I am hyped, because I just learned about a low-cost #airpurifier.
CR-boxes.
They use MERV-13 filters instead of HEPA. The trick is simple. These things are slightly less effective in catching particles, but you can push much more air through them. Less resistance 👾. Hence a unit is quiet like a wine fly. And #airpollution is gone with the wind
There’s even a click-baity clip.👇
