Your Synergy S40 series vacuum has captured a full load of dust, hair, fur and other nasty particles, so make sure it all stays locked in the bag with these HEPA media bags.
These bags designed just for the new Synergy S40 models feature the yellow self-sealing bag collar. Remember to replace the bag when it's two-thirds full.
These bags will not fit X9 or G9 models. For those machines, see part SXH-6.
