Maintaining your machine
Replace your filter when prompted to keep your machine working at its best.

Replacing the filter
To ensure optimum air purification performance, we recommend replacing your 360° Combi HEPA and Activated carbon air purifier filter every 12 months.

Frequently asked questions
We recommend replacing the HEPA and Activated carbon filter every 12 months. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen.
No. Some purifiers rely on you changing, washing and drying the filters each month. The time spent waiting for the filter to dry is time without a working purifier. With the Dyson Purifier Hot+Cool range, you don’t need to waste time washing and drying the filters. The indicator is designed to remind you when it is time to replace the filters.
Dyson purifiers are optimal when left switched on in Auto mode. This allows the purifier to constantly monitor your air quality, and automatically sense and capture pollutants. It adjusts the airflow speed, only purifying when needed
