@Texan_Reverend@kind.social I built one of these a long time ago, when I learned that I had lung damage.
It works excellently. You can use a single filter on a fan if you're too broke to afford 5, but it doesn't last nearly as long.

@Stinkie@mastodon.social Indeed. The four filter arrangement gets better airflow for the fan, and the filters will generally last around four times as long as a single one, if not longer. So, the cost over time is usually better with the full CR Box. If you can afford the up-front cost, they're also cheaper per unit as a 4-pack than they are individually. A single filter is $17-30, depending on the store. The 4-pack is $60 from Costco, making them only $15 each. But if all you can afford is 1, it still works.
