Learn how to build a Corsi-Rosenthal box. The device was created to provide significant reduction in the amount of virus-laden, aerosol particles that are in the air. Follow along as Dean Richard L. Corsi, co-inventor, shows you the major components of this device, and how to build one.
Background:
This air cleaner is a homemade system that is useful for lowering the levels of respiratory aerosol particles
My preferred method is to take a strong fan and put it inside a cardboard box with a hole cut just big enough for the fan to eject air from the box and make a vacuum. Then you simply need one filter big enough to cover the top of the box, not four filters, it still works great!
Squirrel cage style fans are typically going to be more effective at making a pressure differential too just because of the shape. A good strong floor fan, the kind for drying out puddles, is absolutely fantastic for this.
Beyond that a good N95 mask will do wonders for making life more bearable while out in public! They really do manage to scrub out a lot of the particulates if you get a good fit and they come in cool colors these days.
