The Dyson DC18 Slim was built around a tight, compact air path, and that path only works when the exhaust filter is clear. This replacement HEPA filter cartridge, referenced as part 10-2317-02, seats in the DC18 post-motor housing and returns the machine to full exhaust filtration and full airflow. It is the part to order when a DC18 has gone quiet on suction, when the filter cartridge has turned gray, or when the exhaust carries a stale smell.
Because the DC18 is a slim-body upright, it has less filter surface area to spare than a full-size machine, so a partially loaded cartridge shows up as lost suction sooner. Owners often chase a suspected clog or a failing motor when the real cause is a filter that has quietly reached the end of its service life. Dyson guidance for HEPA cartridges of this type is replacement every six to twelve months depending on how hard the machine works.
Built for
Owners of the Dyson DC18 Slim, DC18 All Floors, DC18 Total Access and DC18 Full Kit, plus service techs replacing exhaust filtration during a tune-up. Use it when the cartridge is discolored or when airflow has fallen off with a clean bin.

Frequently asked questions
Can I wash this DC18 HEPA filter instead of replacing it?
No. This post-motor HEPA cartridge is not a washable filter. Washing it can damage the pleated media and it should be replaced when it is dirty.
Which DC18 versions does it fit?
It fits the DC18 Slim, DC18 All Floors, DC18 Total Access and DC18 Full Kit. All of them use the same post-motor cartridge.
How often does it need changing?
Every six to twelve months for most households. Heavy pet-hair use, construction dust or daily vacuuming pushes it toward the shorter end of that range.
What part numbers does this replace?
It is referenced as 10-2317-02 and 911677-02. Either number on your old cartridge indicates the same part.
My DC18 lost suction. Will this fix it?
If the bin is empty, the hose is intact and the brush bar is clear, a loaded post-motor filter is the most common remaining cause of low suction on this model.
