I suggest Respirators for each member of your household in case of outbreak. HEPA filters in your rooms where you sleep to minimize spread of contagious germs and other allergens.
Plus clean air is just nice.
In the event of an emergency or pandemic theres no telling where it will originate but that its about waiting until the CDC can respond in time before it gets to your neighboorhood. In the meantime while everyone is rushing to buy microbial wipes and face masks your already inside your hermetically sealed home waiting for the end of the world. hahahha HAPPY HUNTING YOU SEE THAT ZOMBIE DUDE!!!
Seal Flu - OUT.
