This project would take 2-3 days to filter the volume of air in a 1,000 sq foot apartment... which is to say it would do nothing of significance. To be effective, you want to change the air something closer to once every 30 minutes.

I agree that it would be silly to expect this thing to purify air for an entire living space.

With a few adaptations, however, it might be good as a soldering station fume extractor. These already exist and are little more than a tube, a fan, and a filter (usually with activated charcoal).

The nice thing about this one is that it's circular and could easily adapt to a flexible tube and you could perhaps stack fans for greater sucking power.
