Dyson Pure Cool Link™

Let's get your machine working.

See all steps

Replace the filter

Ensure the purifier is unplugged. To replace the non-washable filter unit, complete the following steps:

Press both buttons to lift the loop amplifier.

Remove the old filter assembly. To dispose of your old filter unit place it in your household waste bin.

Lower the new filter into the housing and the complete unit onto the main body.

Lower the loop amplifier onto the base until it clicks and locks.

When you have re-assembled your purifier, press and hold the 'Standby ON/OFF' button on the remote for 6 seconds.

  • A clockwise rotating pattern will be shown on the LED display
  • Once the loading pattern is complete, the purifier will return to its normal usage

Is there anything else we can help you with?

WiFi information and serial number

Write down the purifier's WiFi password before proceeding with any checks. The serial number and WiFi information can be found in the following locations

On the front of the instruction manual.

On the remote control packaging.

On a removable sticker on the front of the purifier.

On your purifier, located underneath the filter.

The purifier's password is made up of numbers and lower case letters only, so '0' is definitely the number zero.

The number '1' and the letter 'l' (L) may look similar, as may the letters 'j' (J) and 'i' (I).

Factory reset

As a last resort, you can factory reset Amazon Echo to give it a completely fresh start. There is a reset button next to the power adapter. You'll need to use a pin (or something equally small and pointed). Simply hold the button in until the light ring turns orange.

Please note, this will wipe everything and your Amazon Echo will need to be set-up again. This action should only be used as a last resort.

Installing and setting-up Alexa

To get started with Amazon Echo, place the device in a central location (at least eight inches, or 20cm, from any walls and windows). Plug the power adapter into Amazon Echo and then into a power outlet. The light ring on Amazon Echo turns blue and then orange. When the light turns orange, Amazon Echo greets you.

Next, you'll need to downlaod the Alexa app. Go to the app store on your mobile device and search for 'Alexa app'. Then select and download the app. Launch the Alexa app and ensure the account details are filled out. In the Alexa app, open the top left menu. Select 'Settings', then 'Set up a new device'. On the top of your Echo, press and hold the 'Action' button for five seconds. The light ring turns orange and Echo will connect to your mobile device.

Back on the Alexa app, select home Wi-Fi network and enter your home Wi-Fi password. Select 'Connect'. A confirmation message will appear in the app.

Tip: If your Amazon Echo doesn't connect to your Wi-Fi network, unplug and then plug the device into a power outlet to restart it. If you still have trouble, reset your Amazon Echo to its factory settings and set it up again.

Try talking to Alexa. You'll find that you can now use your Amazon Echo device. To get started, say the 'wake word' (Alexa) and then speak naturally to Alexa. Once you've set-up the Dyson skill, remember to use the trigger word (Dyson), preempted by the command 'ask/tell'. For example, "Alexa, ask Dyson purifier to turn on".

Your Amazon Echo device is set to respond to the wake word "Alexa" by default, but you can use the Alexa app to change the wake word at any time. In the app, go to 'Settings', select your Amazon Echo device and then select 'Wake Word'.

Connecting for different product combinations:

If you have the Dyson Link app and Alexa app both installed, and your Dyson machine and Amazon Echo are both connected, but your Dyson skill is not enabled:


Ask Alexa to enable the Dyson skill, or search for Dyson in the skills section of the Alexa app. Then select the 'Enable skill' button. Allow the Alexa skill to access your Dyson Link app account. Enter your Dyson Link app account details and select 'Allow' on the confirmation screen.

If you have the Dyson Link app installed, your Dyson machine is connected but the Alexa app is not installed and your Amazon Echo is not connected:


First, check the Wi-Fi signal strength where your Amazon Echo is positioned, by using a device known to be working. Remember to place your Amazon Echo at least eight inches away from any walls or windows, in a central location. Ensure the power adapter is plugged in and switched on.


The light ring on the Amazon Echo will turn blue then orange. When the light turns orange, Alexa greets you. Next, download the Alexa app to set-up your Amazon Echo.

In the Alexa app, open the main menu and select 'Settings' and then 'Set up a new device'. Press and hold the 'Action' button on your Amazon Echo for five seconds. The light ring will turn orange and Echo will connect to your mobile device.

Next, select your Wi-Fi network and enter your Wi-Fi password. Then press 'Connect'. A confirmation message will display in the app.

Currently, the Dyson skill and voice control for Dyson connected machines are available in the UK and the US only.

If you have more than one Alexa-controlled Dyson machine, your voice commands should make it clear which one you want to control. You can include a word like 'purifier', 'fan' or 'robot' in your command so Alexa knows which one you mean.

If you have two or more similar machines, like a purifier in your kitchen and another in your bedroom, you can assign location labels to differentiate your machines.

Navigate to your machine's settings by selecting the cog icon on your machine's status screen. From here, select 'Your machine's settings'. If you're using a purifier, select 'Room name' and choose the appropriate location. If you're using a robot, choose 'Robot name' and select a room from the predefined list.

If you own an Amazon Alexa-enabled device, you can control and monitor your Dyson connected machines using your voice. Simply enable the Dyson skill to do this.

To enable the Dyson skill, begin by saying the following: "Alexa, enable the Dyson skill." Alexa will respond: "OK, I've enabled the Dyson skill for you, but it requires you to link your Dyson account." Next, in the Alexa app, search for Dyson skill. Then select 'Enable' and follow the on-screen instructions to link your accounts.

To disable the Dyson skill, search for Dyson skill in the Alexa app and choose 'Disable skill'.

Alexa Voice Remote faults

If the Alexa Voice Remote doesn't pair or work wih your Echo device, here are some common solutions that may help.

Keep in mind that the Alexa Voice Remote is only compatible with Echo and Echo Dot. It is not compatible with other Alexa-enabled devices (such as Amazon Tap or Amazon Fire TV). Please make sure you're using the Alex Voice Remote for Echo and not the Alexa Voice Remote for Fire TV.

First, try replacing the batteries. Sometimes batteries lose charge if they've been sitting around for too long. If you have them, insert two new AAA batteries into the remote. If you insert new batteries into your remote, make sure the batteries are in their correct orientations.

Try to pair the remote again, moving closer to your Echo device. In the Alexa app, open the left navigation panel, and then select 'Settings'. Select your Echo device, and then select 'Pair Remote'. You may also see Forget Remote in the app. This means that a remote is already paired with your device. If your'e replacing your current remote, select 'Forget Remote'.

Press and hold the Play / Pause button on the remote for five seconds to start the pairing process when instructed.

Your device searches for your remote and connects to it within 40 seconds (this may take longer, depending on your connection speeds). When your device discovers your remote, Alexa says, "Your remote has been paired."

Press the Talk button on the remote to see if Alexa responds. If the steps above don't work, you may need to restart your device. Disconnect the power adapter (from the back of the device or from the power outlet), and then plug the power adapter back in to the device. After the device restarts, try to pair your remote again.

When you pair the remote, continue to press and hold the Play / Pause button until Alexa says, "Your remote has been paired."

Wi-Fi connection issues

It is important to ascertain if the issue is with Alexa/Echo, or with the Dyson product. Try asking Alexa a general question, such as 'Alexa, what is the weather for tomorrow?'

Operate your Dyson product manually-use the remote or controls to turn the purifier on, or press the power button on the robot.

Echo’s connectivity status is indicated by the power LED on the bottom rear of the device, with white meaning good and orange denoting no Wi-Fi connectivity. If you’re experiencing intermittent connectivity or non-existent Wi-Fi connectivity with your Amazon Echo, here's what to try.

First, reboot your router and turn your Echo off and on again, waiting at least 10 minutes to give time for them to reconnect. Whilst waiting, you can also try re-positioning your Echo away from devices that may be interfering with the signal.

You can also reduce the congestion on your Wi-Fi network by removing unused devices from the network.
If you have a dual-band modem, you may effectively have two networks set up. Try switching the device from the 2.4GHz frequency to the 5GHz frequency or vice-versa.

5GHz promises less interference, better speeds and a more stable connection and it is often less congested.


Alternatively, 2.4GHz can better for devices that may be further away from the router, especially if the signal has to pass through walls.

Move your Echo to higher ground, like a bookshelf, to avoid signal interference.

Quick fixes

The power LED on the Amazon Echo device shows the current status of your Wi-Fi network. Amazon Echo devices connect to dual-band Wi-Fi (2.4GHz / 5 GHz) networks that use the 802.11a/b/g/n standard. The devices do not support ad-hoc (peer-to-peer) networks.

You can locate the power LED near the power adaptor port on the device. Which light is visible?


Solid white light: Your Amazon Echo device is connected to your Wi-Fi network.


Solid orange light: Your Amazon Echo device is not connected to your Wi-Fi network. See connection faults.


Blinking orange light: Your Amazon Echo device is connected to your Wi-Fi network, but can't access the Alexa Voice Service.

If you have multiple devices on your Wi-Fi network, you may have inconsistent Wi-Fi performance. Turn off devices you aren't using to free up bandwidth on your network.

Move your device closer to your router and modem, if it's in a different room or blocked by an object. Make sure your device is away from sources of possible interferance, such as a microwave oven or baby monitors.

(Optional) You could connect to your router's 5 GHz Wi-Fi frequency band (if it's available). Many Wi-Fi devices only connect to the 2.4 GHz band. If multiple devices use this band on your network, your network speed may be slower. You can connect to the less congested 5 GHz band for better range and less interference.

You can restart your Echo device, Internet modem, and/or router to resolve most intermittent Wi-Fi issues. Turn off the router and modem, and wait 30 seconds.

While your network hardware restarts, unplug the power adaptor from your Echo device for three seconds, and plug it back in. Turn on your modem, and then wait for it to restart.

After you restart your modem, turn on your router, and then wait for it to restart. After you restart your Echo device and network hardware, try to connect to your Wi-Fi network again.

Make sure you know your network password (if required). This password is not your Amazon account password. Verify if other devices (such as tablets or mobile phones) can connect to your network.

If not, there may be a problem with your Wi-Fi network. You should contact your Internet service provider, network administrator or the person who set-up your network, for assistance.

Your Alexa device should be on the same Wi-Fi network as your smart home device. Alexa and smart home devices work best on personal Wi-Fi networks. Wi-Fi networks at school or work may not allow unrecognised devices to connect.

You can check or change your Wi-Fi setings in the Alexa app (Please note that an Amazon Echo device and Dyson connected product will still work if on different networks). In order to simplify diagnostics, and for best practice, it is better if they are on the same network.

From the Menu, select 'Settings'. Select your Alexa device. Select 'Update Wi-Fi'. Follow the instructions in the app to update your Wi-Fi information. Note: Some smart home devices can only connect to the 2.4GHZ Wi-Fi band. Check with your smart home device manufacturer for more information.

If you saved your Wi-Fi password to Amazon, but you recently changed the password, you'll need to re-enter your new Wi-Fi password to connect again. By default, your router may use both WPA+WPA2 for security. To resolve connection issues, switch the router security type to either WPA or WPA2 only. If the router also has an option to set the type of encryption, setting it to AES only is recommended.

If your Amazon Echo is unresponsive, or you want to give your device to someone else, you can reset the device. After you reset your Amazon Echo device, you need to register it to an Amazon account and re-enter any device settings to use it again.

To reset your Amazon Echo device: Use a paper clip (or similar tool) to press and hold the Reset button for five seconds. You can find the Reset button at the base of your device.

After you press and hold the Reset button, the light ring on your Amazon Echo device turns orange and then blue. Wait for the light ring to turn off and on again. The light ring then turns orange and your Amazon Echo device enters set-up mode. Open the Alexa app to connect your device to a Wi-Fi network and register it to your Amazon account.

Say, "Alexa, Discover devices". Alexa confirms the start of the search. When discovery is complete, Alexa cofirms the discovery, or says that no devices were found.

If you're unable to access the Alexa app, please try the following:

iOS fix: Begin by restarting your iPhone, iPad or iPod touch. Force close the Alexa app. Then uninstall and reinstall the Alexa app. Once uninstalled, go to the App Store and install the Alexa app again.

Android fix: Restart your Android device. Force close the Alexa app. From the Home screen of your Android device, go to Settings >Apps (or Applications). For some devices, you may need to select Manage applications next. Locate the Alexa app from your list of installed apps and then select Clear Data. After you clear the application data, select Force Stop. Uninstall and reinstall the Alexa app. After you uninstall the app, go to Google Play and install the Alexa app again.

Web Browser fix: Reload the web page. Clear the cache and cookies from your browser. When you clear the cache and cookies, this removes any website settings (such as usernames and passwords) from your browser. Close your web browser and open it again.

If you don't receive a response from Echo, you can:

Check that your Amazon Alexa has power and that the power cable has not become dislodged. Turn upside down to check, as the connector can be hidden by the base.

Check for the 'E' fault on your purifier or for a light ring fault on your robot.

Try asking a general non-Dyson-related question to see if Alexa gives a response. For example, "Alexa, what is the weather forecast for tomorrow?" This can help indicate if the Echo is within range.

Check the colour of Alexa's light ring. If one of the following lights is showing:

Solid blue with spinning cyan lights: The device is starting up.

Orange light spinning clockwise: The device is connecting to your Wi-Fi network.

Solid blue with cyan pointing in the direction of person speaking: Alexa is processing your request.

All lights off: The device is active and waiting for your request, or switched off.

Solid red light: You have turned off the microphones on your device. Press the microphone button to turn on the microphones.

White light: You are adjusting the volume level on your device.

Continuous oscillating violet light: An error occured during Wi-Fi set-up.

If you haven't resolved the issue, you can try checking the colour of Alexa's LED light. The power LED shows the current status of your Wi-Fi network. Please note that Amazon Echo devices connect to dual-band Wi-Fi (2.4GHz / 5 GHz) networks that use the 802.11a/b/g/n standard. The devices do not support ad-hoc (peer-to-peer) networks. You can locate the power LED near the power adapter port on the device.

Solid white light. Amazon Echo device is connected to your Wi-Fi network.

Solid orange light. Amazon Echo device is not connected to your Wi-Fi network. See the 'Wi-Fi connection faults' section for more information.

Blinking orange light: Amazon Echo device is connected to your Wi-Fi network, but can't access the Alexa Voice Service.

If you're still experiencing issues, please check the following:

Is your Dyson machine still working? Check by making a request through the Dyson Link app directly. For example, try setting a fan speed or activating your robot.

Check the latest version of the Dyson Link app is downloaded. Check the latest version of the Alexa app is downloaded.

Try to disable and then re-enable the app via the Alexa app skills page. If this doesn't work, try deleting and then reinstalling the app.

Check your device (phone or tablet) is running the latest/compatible operating system. If not, install the latest vesion to update the firmware.

Check power to the router and connection to wall socket. Check the router signal strength at your Dyson machine's position using a device known to be working.


Is your Dyson machine set-up correct?

Is Echo within range of the router?

Has the network password been changed recently?

Ensure the frequency is 5/2.4. Is the same network for Echo and machine being used?

If the above steps don't work, please read the 'Wi-Fi connection faults' section for more information.

If you're unable to access the Alexa app, please try the following:

iOS fix: Begin by restarting your iPhone, iPad or iPod touch. Force close the Alexa app. Then uninstall and reinstall the Alexa app. Once uninstalled, go to the App Store and install the Alexa app again.

Android fix: Restart your Android device. Force close the Alexa app. From the Home screen of your Android device, go to Settings >Apps (or Applications).

For some devices, you may need to select Manage applications next. Locate the Alexa app from your list of installed apps and then select Clear Data.

After you clear the application data, select Force Stop. Uninstall and reinstall the Alexa app.

After you uninstall the app, go to Google Play and install the Alexa app again.

Web Browser fix: Reload the web page. Clear the cache and cookies from your browser.

When you clear the cache and cookies, this removes any website settings (such as usernames and passwords) from your browser.

Close your web browser and open it again.

Your commands should be in the five 'stages', clearly stated, with a specific single command or question at the end. Speak naturally and at a normal level. The stages are:

Alexa (wakes up Alexa)

Ask/tell (common to all Amazon skills, it will differentiate the end point)

Dyson (trigger word for Dyson connected products)

Purifier/robot (distinguish between products if switching the product on/off, or if multiple products are connected)

Kitchen/bedroom etc. (only necessary for multiple similar products)

To turn on/to enable auto mode/what the air quality is/how to replace the filter (command or question)

If there are multiple commands (Alexa, ask Dyson purifier to turn on and enable auto mode), the request will be difficult for Alexa to interpret, and you may be asked for clarification.

If the trigger word is not used (Dyson) then the request will not work. This is the same if the wake word (Alexa) is not used.

Is your router broadcasting a 2.4 GHz network?

All Dyson connected machines use WiFi to connect to the internet. There are two frequency bands commonly used for a WiFi communication: 2.4 and 5 GHz.

Dyson connected machines only use 2.4 GHz band. Many modern routers support both bands - this is known as a dual band router.

Your router will need to be broadcasting a 2.4GHz network for your appliance to connect.

How to check if your router is a dual band router

Sensitivity settings

Your Dyson Pure Cool Link purifier fan will complete a calibration cycle for up to six days from first use.

Within the settings for the Dyson Link, you can also adjust the target for the air quality sensitivity of your machine.

A more sensitive air quality target will mean that your purifier is active for longer. Some environments may require this in order to maintain a good air quality level.

Please note we would advise allowing your machine to run for at least a week before adjusting the sensitivity settings within the Dyson Link app, to ensure it completes its initial calibration cycle.

Please select the appropriate option

Select settings by swiping up on the home page.

Tap the air quality target option.

Tap on one of the air quality sensitivity options.
