I hear unusual noises, such as rattling or wheezing, from my Dyson air purifier. It might be that the clogged filter is causing the issue. How do I check if the air filter is clogged?

If your Dyson air purifier is rattling or wheezing and you suspect a clogged filter, here's how to check:

The Dyson air purifier's indicator light should be checked first. The red or flashing light indicates your air filter needs cleaning. Check the filter indicator light on most Dyson air purifiers.

Air purifier airflow indicators are another sign to look for. Airflow may be reduced if the machine is clogged. If airflow decreases, clean your Dyson filter.

As you mentioned, strange air purifier noises can indicate a dirty filter. Clogged filters may make rattling or wheezing sounds preventing airflow.
