Unbox your new Dyson filter. Remove any packaging or plastic wrapping.

Align the new filter with the housing and then put it back to the base of the device.

The filter should fit snugly inside the base. Ensure it is seated correctly and evenly all around.

Place the top section back onto the base. Align the two parts and twist the top section clockwise (to your right) until it locks into place.

Plug the device back in and turn it on to ensure it’s working properly with the new filter.
