Maintaining your machine
How to replace your Dyson purifier fan filter
Monitoring your Dyson filter's life is easy. Watch how you can get this information on your Dyson Pure Hot+ Cool to know when to replace your filter and how to replace it.
Cleaner indoor air, day after day
Over time, purifier filters can get clogged up with microscopic pollutants, and even let unpleasant odours back into the room. That's why we recommend changing your filter when your machine alerts you - so it keeps on running effectively, for a cleaner environment.
Frequently asked questions
Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifying fan's speed settings as the temperature changes. For personal cooling in summer, use settings 4-10. In colder periods, enable diffused mode. It projects air through the back of the machine, to avoid unwanted cooling.
If you're concerned by the brightness of your purifying fan's LED display, consider enabling Night-time mode using your remote control or the Dyson Link app. During operation, a small moon icon indicates that your purifier is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.
If auto mode is enabled, AUTO will be illuminated on your purifying fan's LED display. When your machine is purifying the air, AUTO will be in white. When the air in the room is clean, it will turn green and your purifying fan will remain idle until pollutant levels rise.
Your purifying fan's auto mode is designed to manage the air quality in your home without you having to operate the machine – so it's only on when it needs to be. If you or someone in your home suffer from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.
Your purifying fan is engineered to purify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there is at least a few feet of clearance on all sides so that the air can circulate effectively.
Your purifying fan works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air in your home, which means your machine will take longer to work.
We recommend replacing your filter at least every 12 months for optimum filter function, or sooner if your machine alerts you. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room.
The Dyson Purifier remote contains a button battery. Please read Important safety instructions for product containing button/coin batteries.
