Exactly the reason you stated. When you shut the fan off it is stagnant air. That is why the air seems fresh when the fan is on. Particulate matter does not suspend in the air, the fan keeps the air moving.

the fan accelerates the air flow around you. This allows your body to eliminate calories faster. But of course it will work only if the air is at least a bit colder than your own temperature.

when the air rushes over your oily or perspiring skin, the moisture evalorates and cool the skin. turning off the fan stops the air movement.

It doesn't always feel that way ... if it's humid it still feels stale if you ask me...
