What Does F With 3 Bars Mean On Dyson Fan?

If your Dyson fan displays an “F” with three bars, it’s signaling that the HEPA filter needs to be replaced. The error code will appear on the lower front part of the device, and it will remain there until you reset the filter light indicator after replacing the filter.

In addition to the on-device error, Dyson will notify you through their app when it’s time to change the filter. The app provides guidance on how to replace the filter and where to purchase a new one. To access these features, download the Dyson Link app to your mobile device.

How Often Should You Change The Dyson Air Filter?

The HEPA filter in a Dyson fan typically requires replacement every 12 months, though more frequent changes may be necessary depending on the environment where the fan is used. For instance, placing the fan in a kitchen or near an open flame can reduce the filter’s lifespan.

Under normal usage of about 12 hours per day, the filter can last approximately 4,000 hours. Failing to replace the filter will lead to a buildup of pollutants, causing a bad odor to circulate in the room.

Dyson also offers a warranty that covers defects in the filters for the same 12-month period. These replacement filters are compatible with Dyson tower, desk, and personal fans. It’s important to purchase only genuine Dyson filters that are suitable for your specific fan model.

Here are some tips to keep in mind when buying a filter:

1. Identify your Dyson fan’s model number.
2. Purchase only from authorized Dyson retailers.
3. Consider buying filter sets to save money if possible.
