I see lots of chemistry youtubers doing things that make me cringe these days, and no one even uses proper filtration systems to keep toxic chemicals out of the environment or worse, their lungs.

Well no more of that: This simple open source bubbler is an affordable way that toxic gases and hazardous particulates can be removed, partially or entirely, from a gas stream. For powders simply add surfactants and perhaps ultrasonic agitation, and for gases, simply add something to the liquid that reacts with those gases readily, or a fluid in the column that absorbs them. Keep in mind chemical and plastic compatibility charts, and use at your own risk, but hopefully this helps make the world a safer and cleaner place.
