The post-motor HEPA filter is the last thing your Dyson DC33 air passes through before it returns to the room, which makes it the part that decides what your household actually breathes. This replacement HEPA filter fits the DC33 bagless upright and restores full exhaust filtration on a machine whose original filter has grayed, clogged or started to smell. For allergy and asthma households, and for anyone vacuuming pet dander, it is the single cheapest way to bring a working DC33 back to the filtration level it had new.
A loaded post-motor filter does more than pass dust. It restricts airflow, which makes the motor work harder and run hotter, and it is a common cause of the burning or musty odor owners notice months before they think to check the filter. Filter makers for this model advise rinsing the washable pre-motor filter about once a month and replacing filtration media roughly every six months under normal household use.

Frequently asked questions
Is the DC33 post-motor HEPA filter washable?
No. The post-motor HEPA filter on this model is not designed to be washed and should be replaced when it is dirty. The pre-motor filter is the washable one.
How often should I replace it?
About every six months under normal household use. Replace sooner if you vacuum pet hair daily, if the media looks gray, or if the exhaust has an odor.
Why did my vacuum lose suction even though the bin is empty?
A loaded post-motor filter restricts the exhaust path. Airflow through the whole machine drops, so the vacuum feels weak at every attachment even with a clean bin.
Does this fit the DC33i as well?
Yes, this filter covers the DC33 and DC33i bagless uprights. Confirm your model badge before ordering if you are unsure.
Do I need tools to change it?
No. The post-motor filter lifts out of its housing and the replacement drops into the same seat.
