Bummer. Operating at 25 db would have been really impressive for a room filter but it looks like it’s not even close. Extrapolating from David Elfstrom’s airflow estimates it looks like ~1/2 cfm would put it >40 db, which isn’t great. So if we want to create a satisfactory occupant experience we probably shouldn’t put down the tin snips just yet.
