Cleaner indoor air, day after day

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

How often do the filters need to be changed?

The combination filter needs to be changed after 12 months, based on 12 hours’ use a day. The Dyson Cryptomic™ filter is permanent, so you don’t need to change it. 

Is my purifier filter covered by the Dyson warranty?

Yes. Your Dyson purifier filter is guaranteed against original defects in materials and workmanship for a period of 12 months from the date of purchase. Filter units that must be replaced because the filter life has expired are not covered by the warranty.

Does the LCD display stay on throughout the night?

If you're concerned by the brightness of your purifying fan heater's LCD 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.

How do I know when my purifying fan heater is in Auto mode?

If auto mode is enabled, AUTO will be illuminated on your purifying fan's LCD display. When your machine is purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifying fan heater will remain idle until pollutant levels rise.

How long should my purifying fan heater be turned on for?

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.

Where should I place my purifying fan heater?

Your purifying fan heater 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.

Should I keep the windows open or closed?

Your purifying fan heater 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.

Should I change the fan settings in different seasons?

Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifying fan heater'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.

Can I control heating settings remotely through the Dyson Link App?

The Dyson Link App will not control heating remotely due to UL 1278 compliancy: This machine is compliant with safety standard UL 1278, as required by the US Government for all portable connected heating appliances. To comply with the standard, heating and temperature control are not available in the Dyson Link app. Please use your machine’s remote control instead.
