That air filter will move such a small volume of air, it's basically useless unless you're in a small closet.

Well, my experience refutes that opinion, but yes, it sized for a smaller room or less polluted larger areas.

My office is approximately 12' x 12' x 8' or 1,152 ft³. That means the room's air would (theoretically) completely pass through the filter every 20 1/2 minutes. As the article explains, even the lower quality filter in the Ikea air purifier is so close to 100% efficient that it isn't worth worrying about, so completely filtering the air three times per hour is nothing to sneeze at...

And the cost is negligible - the fan might cost $0 to $10, filters are $20/year, and electricity usage is around 2 watts or probably under $2/year.
