HEPA 14 filters are made (and tested!) to ensure that particles of a certain size are reliably captured. Quarantined if you will. Once captured the virus dies in a relatively short time. (more on that later, but in the meantime don’t fall for the ‘We kill the virus’ hype, it will die of old age on its own once captured)
Virus size is much much smaller than a HEPA filter is designed or capable of capturing. Let’s say that a virus is the size of a marble. Lucky for us, we don’t have to try to capture that directly. You see the virus is contained in spit droplets in the air that are much larger than marbles. More like basketballs. So picture basketballs full of marbles. If we do a good job of capturing the basketballs, we get the marbles too!
Now even the basketballs are small in comparison to say a sofa. But while sofas can only be carried and pushed around, basketballs bounce off stuff, and careen around like a pinball in an arcade game, so they get caught in the HEPA filter too because of Brownian Motion and Diffusion. So a HEPA 14 grade filter will do the job just fine.
We don’t have to make this harder than it is, or more complex just to have a ‘differentiated marketing message’. We aren’t competing with anyone. If somebody comes along that will provide something better and cheaper than BAM Air then Yay! Prove it though, with you know, sciency stuff like data and testing please.
In the meantime, let’s get this into as many classrooms as possible as quickly as possible. You with us?
Stay safe and be kind to yourself and others today.
