A conversation with Roman Czech about corona and how cleanroom technology can help.

How do viruses spread through the air?
What are aerosols, what are particles and how do they behave?
How big are the droplets through which viruses can spread?
What technical options can we use to protect ourselves from infection?
What options are there for filtering viruses and bacteria out of the air?
What are the advantages and disadvantages of each option?
What is a HEPA filter and how does it work?
Up to what room size does air filtration work - does the room height also play a role?
How can I get a room virus-free, how long does it take and what happens when an infected person enters it?
What does the air exchange rate mean and which one applies to infected rooms?
Why can't my air conditioning system do this?
Can a HEPA filter like this also be installed in the AC?
Does it also clean surfaces?
How could all this be put into practice, in the office, in everyday life?
