Short YouTube clip (single-speaker) advising on air filter choices and trade-offs: high-efficiency filters can restrict airflow, while very cheap filters only stop large visible debris and fail to capture the fine, invisible particles of concern.

And it's not very good at all because, you know, only thing it's stopping is sandwich bags and Coke cans and anything else you throw at it. Yeah, it's 100% efficient at stopping that. But 98% of what we're trying to stop are the particles you cannot see.
