How To Adjust Temperature On Dyson Pure Cool

With the use of its remote control, you can adjust the temperature on the Dyson Pure Cool in two ways:

Setting the airflow speed

You can control the airflow through the fan's speed and airflow direction. 

  1. In the remote control set-up, locate the airflow speed (left side, second from the top), and air direction (right side, second to the bottom) buttons.
  2. Point the remote control to the sensor on the front side.
  3. Press the (+) or (-) to increase or decrease the airspeed to your comfort. You can set the fan speed between 1-10.
  4. By pressing the air direction button, you can change the flow from front to back or vice versa. Heating only works if the airflow direction is to the front, otherwise, the item is in fan mode.

Controlling airflow distribution

To help regulate the temperature, airflow distribution is a factor. On a Dyson Pure Cool, you can choose to oscillate. Just follow these steps:

  1. Press the oscillate button that is right below the airflow speed button.
  2. Set oscillation. You can choose between five settings: steady,  45°, 90°, 180°, and 350°.

Manipulating the temperature of this appliance is pretty easy. The remote control interface is very user-friendly.

If you notice your Dyson air purifier not cooling effectively, it could be for the following reasons:

  1. There may be an obstruction.
  2. Your filters need replacement.

Do not worry, though—there are ways around these problems. Here are some troubleshooting tips for you.

Clear obstructions

You need to check the loop amplifier and main body of the appliance.

  • To remove obstructions from the loop amplifier, clean using a damp or dry cloth.

Is your Dyson air purifier making an unusual sound? Know what noises you can expect your Dyson Pure Cool to make and which sounds you should be worried about.


Expect your purifier to make clicking sounds when switching airflow direction. This is normal and not a cause for worry.

Low humming noise when off

Even if the purifier is off, its monitors the air quality, temperature, and humidity level continuously. The low humming sounds come from the small fans that maintain airflow for monitoring purposes. 


If you hear a whining or whistling sound coming from your purifier, turn it off for 10 seconds. Ensure the power cord is securely plugged in at the center of the base. Switch it on again and retest. If the whistling persists, check the filter.


For grinding or grating sounds, contact your dealer.
