Relatives moved into house - no appliance manuals left behind.
Range hood needs a least a new filter, but we have no idea of the make, much less model.
Hood is 46.5" at widest. Has distinctive holes for something (?) on the front -- four sets of two holes, each set with smaller above one larger.
Can anyone identify this thing? What are those holes for? (Pic may be upside down - it is not installed that way!)
Thanks!
