Frequently asked questions

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 purifier 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.

How do I know when my purifier fan is in auto mode?

If auto mode is enabled, AUTO will be illuminated on your purifier fan's LED 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 purifier fan will remain idle until pollutant levels rise.

How long should my purifier fan be turned on for?

Your purifier 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 purifier fan?

Your purifier 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.

Should I keep my windows open or closed?

Your purifier 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.

Does the Dyson Pure Cool™ TP4A purifying fan connect to the Dyson Link app?

The Dyson Pure Cool™ TP4A purifying fan works independently and doesn't currently connect to the Dyson Link app. It does not feature app connectivity.

How often should I replace my filter?

The machine will alert you when it’s time to change filters, depending on use we recommend replacing the HEPA + Carbon filter roughly every 12 months, depending on how often you use it. That’s because over time filters can become clogged with pollutants and even let unpleasant odors back into the room.

Why does my new filter come in two parts and is all black, but the previous filter is four parts and is purple and green?

If this is your first time changing your filter, fully remove the purple and green filter from your machine before replacing it with the new, all-black 360° Combi Glass HEPA + Carbon Air Purifier Filter. Dyson has updated the filter for this machine to a 2-in-1 replacement filter that combines both HEPA and carbon filter as one piece, for even more convenient installation and maintenance.

How do I reset the filter level?

It's important to reset your filter life after you have replaced your filter. To reset your filter life, press and hold the Night mode button on your remote control. The display on your machine will countdown from five, the filter life will be reset and your machine is ready to use.
