How small is a micron, and why does it matter?

Airborne particles are usually described in microns. Generally speaking, the human eye can see debris and dust that are approximately 25 microns in size. To understand just how small this is, consider that a single hair from your head averages about 70 microns in diameter or 30 times larger than the largest fine particle.

Article: Micron Ratings in Filters: FleetFilter

Most filter manufacturers will try to offer the ratings on their filters, but many do not. Of the four brands FleetFilter sells (NapaGold by Wix, Fram, Luberfiner, Baldwin), only Wix publishes a nominal micron rating and a beta ratio of their filters.

A basic guide to particle characterization

Particles are 3-dimensional objects, and unless they are perfect spheres (e.g. emulsions or bubbles), they cannot be fully described by a single dimension such as a radius or diameter. In order to simplify the measurement process, it is often convenient to define the particle size using the concept of equivalent spheres. In this case the

What size particle is important to transmission of COVID

If particles of concern are larger than 8-10 microns, improving the building ventilation system will have a very modest benefit, and could in fact create drafts that spread larger droplets – apparently an important factor in several restaurant case studies, where the zone of infected people was non-uniform in the room and roughly consistent with major air currents.
