Pura Blinking Red and Green [TRIED-AND-TRUE FIX!] (2024)

If you have a Pura diffuser, you may have noticed that it sometimes blinks red and green. This can be confusing, but it’s not a cause for alarm. A Pura diffuser blinking red and green usually indicates that it’s offline.

While the specific meaning of this indicator may vary based on the diffuser model, it commonly signals issues related to connectivity, low water levels, or other operational aspects. Let’s explore how you can troubleshoot and fix your Pura device’s red and green blinking issue.

1. Check Your Wi-Fi Connection

For the Pura diffuser to work properly, it requires a steady Wi-Fi connection. Any issues with the connection means the device and app can no longer communicate.

Plug your diffuser into a power outlet
Connect your smart device to the same Wi-Fi network as your diffuser and open the Pura app
Go to “Settings” and select “Wi-Fi”
Check that the Wi-Fi network name (SSD) and password are correct

If the Wi-Fi network name or password is incorrect, update the information and try again:
- Open a web browser and type your router’s IP (check the router’s back or bottom for this information)
- Enter your router’s username and password (located next to where the IP is written) to log in to the configuration page (the default username and password are usually “admin”)
- Select the “Wireless” option (for other routers, it might be the “Wi-Fi Settings,” “WLAN,” or “Wireless Security” option)
- Create a new password in the “Wi-Fi Password” box
- Enter a new Wi-Fi network name

1.1 Check Network Requirements

For the Pura diffuser to work correctly, your network connection must be compatible with the device.

Pura only works on a 2.4 GHz frequency and will not work on 5.0 GHz, therefore:
- Log in to the router’s configuration page
- Click on “Wi-Fi Settings” (or a similar option)
- Toggle on “Band 1 (2.4 GHz)”

If you’re using a hidden network, you must manually enter the network’s name in the Pura app
You can use MAC address authentication by manually adding your Pura diffuser’s MAC address into your network configuration
Ensure you have a consistent power source to maintain a strong connection with the local network

1.2 Reset the Router

A simple reset often fixes most malware problems that could interfere with the network connection. Note that this reverts the router’s username and password to default.

Locate the button labeled “Reset” and ensure the router is on
Press the “Reset” button for about 20 seconds
Wait for a few minutes as the router resets and all lights turn green or white
Check whether the Pura is still blinking red and green

2. Update Firmware

Updates are essential to improve Pura’s stability and security. The manufacturer may release firmware updates periodically to fix bugs or add new features.

Plug your diffuser into a power outlet and connect it to the same Wi-Fi network as your phone or tablet
Open the Pura app
Tap on the “Settings” icon in the bottom right corner of the screen
Tap on “Firmware Updates”
If there’s a firmware update available, tap on “Update”
Wait as the firmware update begins and the diffuser restarts

3. Troubleshoot the App

4. Check the Water Levels

If you encounter performance issues with the diffuser, check if it has sufficient water in the reservoir. Running a diffuser with low water levels can lead to damage, affecting the device’s efficiency.

Unplug the diffuser from the power outlet
Remove the diffuser’s lid
Check the water level indicator on the side of the diffuser:
- If the water level is below the MIN line, refill the diffuser
- If the water level is between the MIN and MAX lines, the diffuser is good to go
- If the water level is above the MAX line, remove some water
Use filtered or distilled water to refill the diffuser (don’t use tap water as it contains minerals that can clog the diffuser)
Fill the diffuser until the water level is just below the MAX line
Replace the diffuser lid
Plug the diffuser back into the power outlet
Check if it’s still blinking red and green

5. Clean the Diffuser

Regular maintenance is crucial to keep the diffuser functioning optimally; clean the device every two to four weeks, depending on how often you use it. Don’t use harsh chemicals to clean the diffuser, as they can cause damage.

Unplug the diffuser from the power outlet
Remove the diffuser lid
Remove the fragrance vial from the diffuser
Wipe down the inside and outside of the diffuser using a damp cloth
If there’s any oil residue on the diffuser, use a mild soap and water solution to clean it
Rinse the diffuser with clean water
Dry the diffuser with a clean cloth
Reinstall the fragrance vial and the diffuser lid
Plug the diffuser back into the power outlet

6. Reset the Diffuser

When you reset the diffuser, it might be restored to its factory settings. This means all your settings, such as the fragrance and Wi-Fi settings, could be deleted, and you’ll need to set them up again.

6.1 Soft Reset

A soft reset only checks and fixes issues with the diffuser without deleting settings or user information.

Open the Pura app and click on the three lines above the diffuser you’d like to reset
At the bottom of your screen, select “More”
Click “Fix My Diffuser” to begin the reset

Press and hold the “Reset” button until the nightlight starts blinking blue
Click “Continue” in your app to follow the remaining steps

6.2 Hard Reset

A hard reset will wipe all your settings, so back up or write down any information you’d not want to lose, such as your Wi-Fi logins.

Open the Pura app and select the diffuser you want to reset
Select “More” at the screen’s bottom
Click “Forget Diffuser” to begin the reset
