Your Pura flashing red and green is basically an error code : it’s your device telling you something’s wrong and it needs attention, most often with Wi‑Fi, power, or the fragrance vials.

What the red and green lights usually mean

Most Pura diffuser guides and tutorials agree that alternating or blinking red and green lights point to one of these:

  • The diffuser is offline or can’t connect properly to Wi‑Fi or the app.
  • There’s a general device malfunction (internal error).
  • Fragrance vials are low, empty, or not seated correctly in the device.
  • There could be an electrical issue: bad outlet, loose plug, or internal damage.

Think of the red‑green pattern as your Pura’s “check engine” light for connectivity and basic hardware issues.

Common causes people report on forums

From troubleshooting guides and community tips, here are the problems users most often run into when they ask “why is my Pura flashing red and green”:

  1. Wi‑Fi or app trouble
    • Pura diffusers can go into a blinking red/green state when they’re offline or can’t talk to the Pura app.
 * Outdated app versions, router changes, or using unsupported networks (like 5 GHz only, hidden SSID, or login‑gated networks) are common culprits.
  1. Power glitches
    • A loose plug, bad outlet, or a brief surge can make the device misbehave and start blinking.
 * Sometimes simply unplugging and re‑plugging into another outlet calms it down.
  1. Fragrance vials / cartridges
    • If a vial is empty, not clicked in correctly, or its sensor isn’t reading, the device may throw an error pattern.
 * People often fix the blinking just by reseating or swapping the vials.
  1. Hardware or internal error
    • Internal malfunctions, electrical shorts, or damaged components can also trigger the red/green flashing.
 * In stubborn cases, users end up needing a replacement from customer support.

Step‑by‑step things to try

Here’s a practical checklist you can follow at home before contacting support:

  1. Check the basics (power and outlet)
    1. Unplug Pura for 30–60 seconds, then plug it back in firmly.
 2. Try a different wall outlet to rule out a bad socket.
 3. See if the lights behave differently after a fresh power cycle.
  1. Inspect and reseat fragrance vials
    1. Remove each vial, check that it’s not obviously empty or damaged.
 2. Reinsert them until they’re fully seated and you feel a solid click.
 3. If one looks suspicious, swap in a new vial and see if the blinking stops.
  1. Fix Wi‑Fi / “offline” issues
    1. Open the Pura app, make sure it’s updated to the latest version from your app store.
 2. Check that your phone is on a supported Wi‑Fi network (typically 2.4 GHz, not hidden, no extra login page).
 3. If the diffuser shows as offline in the app, walk through the reconnect steps or remove and re‑add the device.
  1. Perform a reset (if your model supports it)
    • Many guides suggest holding the reset button (or main button) for several seconds until the light pattern changes, then going through setup again in the app.
 * After resetting, re‑configure Wi‑Fi and schedules from scratch.
  1. When to contact Pura support
    • If it still flashes red and green after power cycling, reseating vials, fixing Wi‑Fi, and resetting, it may be a deeper hardware fault.
 * At that point, most guides recommend reaching out to Pura customer service with your model, serial number, and a description of the light pattern.

Quick FAQ style recap

  • Q: Is my Pura broken if it’s flashing red and green?
    Not necessarily. Often it’s just offline, needs a reset, or has a vial/power issue you can fix yourself.
  • Q: Can I still use it while it’s blinking?
    Many guides suggest resolving the error first, since the blinking usually means it’s not operating correctly or consistently.
  • Q: Do I need a new device?
    Only if the blinking persists after you’ve tried power, vials, Wi‑Fi fixes, and a full reset—then support may recommend a replacement.
