The frequency of air purifier filter changes depends on the air quality, usage, and filter type.
As a general rule of thumb, it’s recommended to change the filter every 12 months for typical usage in the home. You will also be notified on the MyDysonTM or on your machine when it is time to replace your filter.
However, if you live in a highly polluted area or have pets, you may need to change the filter more frequently.
It's important to follow the manufacturer's recommendations and check the filter regularly for signs of wear and tear or clogging.
