we have be use the Miele brand bag for several year but as the price continue to increase and the quantity in the box decrease decide to give these bag a try . we be very pleased ; the bag itself be good quality , the collar be cardboard instead of plastic . Update 2012 : the most recent shipment be not the EnviroCare brand , even though that be what the photo show , but DVC brand . the bag state it come with 2 different filter but none be inside . the EnviroCare brand seem to be of slightly higher quality .
