When your non-washable filter unit needs replacing the appliance will display the pattern shown. To replace the non-washable filter unit, follow these
steps. Ensure your appliance is unplugged. Your Dyson appliance is programmed to remind you to replace the filter unit after 12 months based on
12 hours usage a day. Please note your indicator will activate sooner with more use. The indicator is only a guide. Use in heavily polluted environments
may require the filter unit to be replaced more regularly. Outside air quality can be checked through the Dyson Link app.
