When a Pura diffuser blinks green and red, it’s basically throwing an error code : something is wrong with power, Wi‑Fi, or the fragrance cartridges, and the device has gone “offline” until you fix it.

What the green and red lights usually mean

Most recent guides and how‑to videos agree on a few common interpretations:

  • Alternating red and green usually means a connectivity or general malfunction error (often “offline”).
  • Green by itself is normal: power on/startup or successful connection.
  • Red by itself (blinking) often points to an internal error, cartridge problem, or firmware/Wi‑Fi issue.

Think of the red+green combo as: “I’m powered, but something important isn’t working, so I won’t run properly.”

Most likely reasons your Pura is blinking green and red

From recent troubleshooting guides and tutorials, the blinking red/green pattern usually comes from one (or more) of these:

  1. Wi‑Fi / app connectivity problems
    • Weak Wi‑Fi signal where the diffuser is plugged in.
    • 5 GHz–only or incompatible network (Pura generally expects 2.4 GHz, no hidden SSID, no special login or MAC auth).
 * Outdated Pura app or firmware causing sync problems.
  1. Device is “offline” in the Pura app
    • The app can’t see the diffuser at all, even though it has power, which triggers the red+green error indication.
  1. Empty or low fragrance vials / cartridge issues
    • Cartridges inserted incorrectly or not detected.
    • Cartridges empty or faulty, making the device flag a malfunction.
  1. Power or internal hardware glitches
    • Loose outlet, surge, or short internal fault.
 * The diffuser’s internal sensors detect a malfunction and use the red/green flashing as a diagnostic code.

Quick step‑by‑step fixes to try

These are the common “DIY” steps owners use before contacting support.

  1. Check power and reset the device
    1. Unplug the Pura from the wall.
    2. Wait at least 30–60 seconds.
    3. Plug it into a different outlet if possible.
    4. Press any reset button on the device (if present) and see if the pattern changes from red/green to solid green or off.
  1. Inspect and reseat the fragrance vials
    • Open the diffuser, remove each cartridge, and look for leaks, cracks, or obviously empty vials.
 * Wipe away any residue, then firmly reinsert the vials until they’re fully seated.
 * If one looks damaged or very low, try running the device with a known‑good cartridge.
  1. Fix Wi‑Fi and “offline” issues
    • On your phone, turn Wi‑Fi on and stand next to the diffuser; you should see strong signal bars.
 * Make sure your router is broadcasting a 2.4 GHz network and not just 5 GHz; also avoid hidden SSIDs and networks that require extra login (username/MAC auth).

 * Restart your router, wait a few minutes, then reopen the Pura app and see if the device comes back online.
  1. Update the Pura app and firmware
    • Go to the App Store or Google Play, search for “Pura,” and tap Update if available.
 * Open the app and check if it prompts a firmware update for the diffuser; complete any update and then test again.
  1. Perform a full factory reset (if the manual supports it)
    • Some guides mention holding the reset button for several seconds until the light changes pattern, which triggers a factory reset.
 * After resetting, re‑add the diffuser in the Pura app as if it were new.

If, after all that, the device still blinks red and green continuously, that’s a strong sign of a deeper hardware issue, and you’ll likely need to contact Pura customer support or request a replacement, especially if it’s under warranty.

Mini FAQ and forum‑style notes

“Is this a common problem?”
Yes. Multiple troubleshooting articles describe blinking red/green as a frequent complaint with Pura aromatherapy diffusers, usually tied to Wi‑Fi or cartridge problems and often resolved with simple resets or network fixes.

“Can I still safely use it while it’s blinking red/green?”
You generally shouldn’t rely on it while it’s in an error state, since the code indicates either connectivity loss, incorrect operation, or a possible internal fault.

TL;DR:
Your Pura is blinking green and red because it’s in an error/offline state, most often due to Wi‑Fi/app issues, empty or mis‑seated fragrance vials, or a power/firmware glitch; walk through power reset, cartridge checks, Wi‑Fi fixes, and app/firmware updates, and if the lights persist, reach out to Pura support as it may be a hardware fault.
