Desk-size box-fan air purifier shell

Clean the air round your desk with a fan and filter sheets

A small take on the box-fan air purifier. Line the four honeycomb walls with filter sheets, set a 120 mm computer fan face-up in the round opening in the lid, and it pulls room air in through the filters and blows it out of the top. Quiet enough for a desk or bedside.
