My preferred method is to take a strong fan and put it inside a cardboard box with a hole cut just big enough for the fan to eject air from the box and make a vacuum. Then you simply need one filter big enough to cover the top of the box, not four filters, it still works great!
Squirrel cage style fans are typically going to be more effective at making a pressure differential too just because of the shape. A good strong floor fan, the kind for drying out puddles, is absolutely fantastic for this.
Beyond that a good N95 mask will do wonders for making life more bearable while out in public! They really do manage to scrub out a lot of the particulates if you get a good fit and they come in cool colors these days.








When used correctly drones do what paratrooper used to do, create pressure and chaos a distance away from the main fight in areas that are supposed to be safe. This prevents the enemy from concentrating on you even if the drones by themselves won’t win the thing, kind of like throwing a beehive at someone you’re in a fight with and now he has to worry about you as a primary threat but can’t ignore the bees or they become a cumulative exhausting threat.
Don’t worry, our leadership has fired anyone capable of understanding how to use our weapons the way they’re supposed to be used so now we’re going to follow the Russian route of ‘just throw it all at the enemy to make room for more stuff to throw at the enemy’ because the point is not to win but to grift the military budget.
