The cloth fiter on your Broan is an inverted cloth bag, different than this one. The inverted bag has a weight in the middle that hangs down from the top of the unit with a flexible metal band in the top rim. Pull one side of the rim towards the middle and feed into the rim inside the unit. Once one side is in place, allow the band to return to round and sit above the rim. We don't carry the correct replacement for your model, it is wider than our product.
