why is my pura blinking red and green

A Pura diffuser blinking red and green is usually an error signal, most often meaning the device is “offline” or having a connectivity or functionality issue (not that it’s broken for good).

What the red and green blinking usually means

Most guides and the official support pages agree that alternating or simultaneous red/green lights are an error or status code, not a normal operating mode.

Common meanings include:

  • The diffuser is offline or can’t stay connected to Wi‑Fi/app.
  • There’s a general device malfunction or internal error.
  • There may be a problem with cartridges (faulty, low, or not seated right) in some cases.

Think of the blinking as your Pura’s way of saying: “I can’t function correctly until you fix my connection or hardware issue.”

Main causes (why it’s blinking)

From recent troubleshooting guides and how‑to videos, these are the most common triggers people run into.

  1. Wi‑Fi / app issues
    • Weak Wi‑Fi signal where the diffuser is plugged in.
 * Incompatible network settings (5 GHz only, hidden networks, login portals, MAC authentication).

 * Outdated Pura app or firmware causing sync problems.
  1. Power or outlet problems
    • Loose plug, bad outlet, or intermittent power can trigger blinking.
 * Internal electrical glitches or shorts are less common but possible.
  1. Cartridge / refill issues
    • Low or faulty fragrance cartridges can cause red error behavior on some models.
 * Cartridges not fully clicked into place can also confuse the device.
  1. Internal device malfunction
    • Memory errors, sensor issues, or other internal faults that require reset or, rarely, replacement.

Step‑by‑step: quick things to try

These are the common “first line” fixes that support pages and tutorials walk through.

  1. Check power and outlet
    • Unplug Pura, wait ~30 seconds, plug it back into a different known‑good outlet.
 * Make sure any power strip or smart plug isn’t failing.
  1. Inspect cartridges
    • Eject each fragrance cartridge, check for visible damage or leaks, then firmly reinsert until it’s properly seated.
 * If one cartridge looks suspicious, test with a different one if you have it.
  1. Fix Wi‑Fi / “diffuser offline”
    • Move the diffuser closer to your router and check that your phone shows good signal in that spot.
 * Make sure you’re using a supported network (usually 2.4 GHz; avoid 5 GHz‑only, hidden SSIDs, captive portals, or networks needing usernames/MAC approval).

 * Double‑check Wi‑Fi password and reconnect the diffuser via the app’s setup routine.
  1. Update the Pura app / firmware
    • Open your device’s app store, update the Pura app to the latest version, then reopen and let it sync.
 * If the app offers a firmware update for the diffuser, install it and reboot the device.
  1. Perform a reset
    • Many guides recommend pressing and holding the reset button on the device (often for several seconds) until the light changes pattern, then re‑adding it in the app.
 * After reset, go through the setup as if it were a new diffuser.

When to contact support

If you’ve:

  • Checked power and outlets,
  • Reseated or swapped cartridges,
  • Verified Wi‑Fi and app, updated everything, and reset the device,

and it still keeps blinking red and green or shows as offline, it may be a deeper hardware fault that needs official support or replacement.

Pura’s own help pages explicitly say that persistent “Diffuser Offline” with flashing red and green can require working through their troubleshooting flow and then contacting support if unresolved.
