From the individual perspective the first thing to note, is if you are not infected then a facemask of the sort most people are wearing is going to be more of a hinderence than a help and potentialy more likely to cause you to become infected.
Your best stratagy short term is "Self issolation" but you need to stock up on food and water and flu medications as well as the likes of dioralyte and certain vitimins and minerals and keep as far away from other people as possible.
There are ways you can make air filtration units using wet filters and disinfectants or bleaches in essence they are half a dozen or more plastic meash screens down which water with disinfectant or bleach added flows however this causes them to get into the air, thus you need a second filter using activated charcoal ot similar to absorb the chemicals.
Whilst HEMPs filters are used in hospitals for cleaning air, like face masks they are not upto the job of cleaning out viruses from air.
Theres not much more to be said on the matter unless you can find a way to keep sick people outside of a given perimeter so those inside remain disease free.
