Replacing the HEPA filter
We recommend replacing the HEPA filter every 12 months, or sooner if needed. Always turn off and unplug your machine. Press both catches on either side of the air amplifier and lift off. Remove the filter and dispose of in a household waste bin. Lower the new filter into place and reassemble your machine.
-
Replacing the battery
Start by removing the screw on the back of the remote. After the screw has been removed, push down on the bottom of the remote to release the battery cover. Replace the battery and click the cover back in place, then secure with screw.

Frequently asked questions
We recommend replacing the HEPA+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 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.
