Bah. I had some bids in an auction for some HEPA grade 400cfm air filters, with an RRP of £3,995. I was hoping to pay about £25 each for two of them, but after a few days of being in the lead I got pipped to the post while on a work call.

I wonder if anyone makes replacement grilles for box #fans that:

1. hold an #HVAC #filter on the intake side, and
2. shroud the corners of the output side.

This would be awfully convenient for #AirPurification…

A prefab frame for a #CorsiRosenthalBox would also be interesting.
