Re: Annual Meeting
I'm guessing Advent might be 14 x 14 x 16 (maybe 18), not counting the
vestibule. Probably want around 250 to 300 cfm.
Looks like a BlueAir 311 or Coway Mighty would be appropriate CFM.
Wirecutter likes both, and looks like they rate Coway higher principally on
price.
BlueAir might be quieter - I didn't find dB ratings for the Coway.
I'd be in favor of going ahead with the BlueAir 311. I'm happy to order
one and be reimbursed sometime.
