How do I clean or replace the filter on my Dyson Gen5detect™?

If you're encountering a blockage or loss in performance with your Dyson Gen5detect™, it could be because you need to clean your filter. To do so:

  • Remove the filter by turning it anticlockwise. Gently pull it away from the machine.
  • Before washing your filter, tap it gently over a bin to remove any loose dust and debris.
  • Wash the pleated paper element of your filter first, under warm, running tap water, with the foam element facing downwards.
  • Next, wash the foam element of your filter, under warm, running tap water, with the foam element still pointing downwards.
  • Holding your filter on its side, run warm water over the outside of the foam element, gently rubbing your filter to remove the dirt.
  • Repeat washing until the water runs clear.
  • Empty the filter and shake firmly to remove excess water. Keep shaking until there’s no water coming from the filter.
  • Place the filter on its end and leave it to dry for at least 24 hours in a well-ventilated, warm place.
  • Don’t dry your filter in a dishwasher, washing machine, tumble dryer, oven, microwave or near a naked flame.
  • After cleaning your filter, thoroughly wash your hands using anti-bacterial soap.
  • Check that the filter unit is completely dry.
  • To refit, position the filter unit in place on the main body and turn it clockwise until it clicks into place.
