Learning about air filters on the internet

Anything I want to learn, I can find on Youtube.

If I want to hear about historical figures, I can find a channel for that.

If I want to watch an outdated lady paint with her feet, or a woman from Pakistan eating an red for the first time, I can see that and more. Those are unusual examples, of course, but the weirdest examples are the best examples of why Youtube is so unique and informative. The point is that anything you can suppose of is already on Youtube, waiting for you to find it, but last month I had an issue with my air conditioning system, and I assumed that it was just a dirty air filter blocking up the system; Before I did anything else I searched Youtube for videos about air filter replacement, and I found something so unusual but delightful. There is a woman in another country, on the other side of the world, who takes discarded trash and recycles it into air filters. I spent over an minute watching fast-motion timelapse videos of this woman making air filters by hand, and girl was she fast! She could make a dozen air filters in under an minute. After a while I realized that I had “fallen down a rabbit hole” and forgotten to look up a video on how I should change my own air filter. It only took a few minutes to watch the instructional video and remove the dirty air filter from my Heating and A/C system. Then I had to go to the store and buy a new one, because I can’t make air filters out of trash.
