Lemme go send my air intake through a time machine and as long as the weather keeps changing we can use that to drive air through a filter!

No need for a time machine (or being snarky - I did say it's just for comparison, didn't I? I think it does put the "very high pressure" into perspective)

That said, your time machine idea could be simply implemented with a large, airtight box. Simply put the filter over it and weather changes will push and pull air through the filter with two orders of magnitude more pressure than this little fan. Volume of filtered air will depend on the volume of the box though, so better get a large one.

If you had a time machine you might as well just skip the filter and pull in air from before the industrial revolution directly
