How to Replace the Filters on a Dyson - DC04

Are dirty filters harming your vacuum cleaners suction? The most probable cause for this would be the filters in the vacuum becoming dirty or clogged.

Now there's 2 filters in the DC04, there's this pre-motor filter which filters out fine dust particles which can cause allergies. This are washable and must be washed every 6 months, and you do that by just running it under the tap, but if it's really filthy then I'd just get a new one. There's also this post-motor filter which you must be replaced regularly and isn't washable.

If you’re stuck, don’t worry we are here to help with this easy to follow guide. Soon you’ll have your vacuum performing at an optimum level.

This video shows an example on how to remove or replace the part on a typical machine, some models may be different but the procedure should be similar.

  What You Will Need:

Safety Advice

Safety First! Please ensure that you have disconnected the appliance from the mains before starting any repair.

Pre-Motor Filter

  Step 1 - Removing Old Filter

The pre-motor filter on the DC25 is located in the cyclone assembly. To remove the filter, start by removing the cyclone assembly from the vacuum cleaner body, then click open the top cover releasing the filter inside.

  Step 2 - Replacement Process of the Filter

If your filter is mucky as the one shown in our video, just replace it with a replacement filter. However, if you wish to give it a quick clean to reuse the filter, simply run both halves of the filter under the cold tap, drain out the excess water and leave it to dry for at least for 24 hours.

Once it’s dry, simply pop side the filter in and close the cyclone cover.

Post-Motor Filter

  Step 1 - Removing Old Filter

The second filter is the post-motor filter and this is located under the cyclone assembly. As you already have the cyclone unit out of the way, the next thing to remove is the  post-motor filter cover.

  Step 2 - Refitting the Filter

If your filter has become really dirty like the one in this video, then you might just want to get a replacement. However, if you do want to give your filter a quick clean just run it under cold water and tap off any excess moisture before leaving it to dry for at least 24 hours.

Put the new filter in place followed by the cover- making sure the cover lines up with the housing correctly, as it can easily break.

Finally, put the cyclone and bin assembly back on the vacuum, job done!
