Jesus Christ, I don’t even want to know right now. Hahaha

Shouldn’t that “but” be an “and”?

If you aren’t already, you should be prioritizing air quality in your home. This means frequently opening windows to change over the air if possible — though I understand it’s not always possible due to humidity or pollen. You should also invest in some sort of air filtration system that will remove airborne dust. On a budget, this can be achieved by taping a filter to a box fan.

Indoors is basically a closed system until and unless you open it up.

All of the above will also reduce the risk of spreading airborne disease as you keep the concentration lower.

I found a YouTube link in your post. Here are links to the same video on alternative frontends that protect your privacy:
