Smart air - How big are pollen particles
Pollen particle sizes typically range from 10 microns up to 200 microns — about the width of a human hair. That makes them pretty ‘large’, as far as particles go. They’re bigger than most smog, PM2.5 and soot particles, but smaller in size than heavy dust and sand-like particles.
Can DIY Masks Protect Us from Coronavirus?
DIY masks to protect against from viruses sounds like a crazy idea. Data shows masks work incredibly well, and they’re also really cheap. Surgical masks cost a few pennies, and they’re capable of filtering out 80% of particles down to 0.007 microns (14 times smaller than the coronavirus).
Can Masks Capture Coronavirus Particles?
There is a lot of conflicting information. Do surgical masks capture coronavirus particles? Fortunately, scientists have already accumulated hard data on air pollution masks that can answer these questions.
