Tips for Troubleshooting Common Issues

Dyson air purifying devices are generally reliable and effective at purifying the air in your home, but like any piece of technology, they can experience problems from time to time. Here are some common issues that you might encounter with your Dyson Air Purifier, as well as some tips for troubleshooting them:

The Air Purifier isn’t working at all:

  • Ensure that the device is correctly plugged into a working power outlet and that there are no issues with the electrical circuit in your home.
  • Confirm that the air purifier is switched on and that the filters are clean and free from blockages.
  • If the above steps do not work, reset the device using the steps outlined in the previous section.

The Air Purifier is producing strange noises:

  • Make sure that all the parts are correctly assembled and that there are no loose components.
  • Ensure the device is placed on a flat, stable surface and not blocked by any object.

The Air Purifier is producing an unpleasant odor:

  • Inspect the filters to make sure that they are clean and do not need to be replaced.
  • Confirm that the device is not being used in an area with strong odors or chemicals that could be causing the unpleasant odor.

The Air Purifier isn’t as effective as before:

  • Ensure the filters are clean and have not reached their end of life. Replace the filters if necessary.
  • Make sure that the device is being used in the correct size room and that it is not being overworked by attempting to purify a larger area than it’s capable of handling.

If none of these steps work, contact Dyson support for assistance.


Resetting your Dyson Air Purifier is essential in maintaining its functionality and ensuring that it continues to provide clean air in your home or workspace. Malfunctions, filter changes, or firmware updates of the device may require resetting the unit, but the process is straightforward and can be completed within minutes.

You can easily reset your Dyson Air Purifier by following the simple steps provided in this blog post and restore it to its previous settings. It is also important to note that if you encounter any issues while resetting the unit or if it still does not function correctly after the reset, you can refer to the troubleshooting section for guidance.


How do I clean my Dyson air purifier’s sensor?

Open the small sensor hatch located at the back of the unit. Use a cotton swab to gently remove any debris or dirt from inside the sensor, being careful not to use liquids or cleaning agents that could cause damage.

Is the Dyson air purifier capable of cooling the room?

While it is true that some models, such as the Dyson Pure Cool, have a fan function that can help to circulate the air and create a cooling effect, it’s important to note that their primary function is to improve air quality by reducing air contaminants. 

Is a Dyson fan also an air purifier?

Some Dyson fans come with built-in air purifying technology, while others do not. Fans that have air purifying technology work similarly to Dyson air purifying systems by blowing air through a filter to capture and remove pollutants and allergens from the air.

Why is the orange light blinking on my Dyson air purifier?

The blinking orange light indicates that the Dyson filter needs to be cleaned or replaced. A clogged filter can cause your air purifier to lose suction or airflow, leading to overheating and damage to the motor.
