Bridgewater Pura Smart Diffuser Refill Vial – Sweet Grace 0.33 oz

Swap out an empty vial and the Pura app already knows — Bridgewater's Sweet Grace refill uses NFC to register itself automatically, no setup required.

That one detail makes a bigger difference than it sounds. Most smart diffuser refills ask you to open an app, scan something, or manually select the fragrance. This 0.33 oz vial skips all of that. An encrypted NFC tag built into the vial communicates with your Pura diffuser the instant it's inserted, so the app updates on its own and you get straight to enjoying the scent. Sweet Grace is Bridgewater Candle's signature fragrance — a warm, softly powdery blend that's recognizable without being overpowering, and genuinely pleasant across a variety of rooms and settings. If you run a Pura diffuser and you've been hunting for a refill that actually works the way the system promises, this is it.

• NFC auto-detection: Encrypted NFC tag registers with your Pura smart diffuser automatically on insertion — no QR codes, no manual fragrance selection in the app.
• Up to 336 hours of fragrance: Each 0.33 oz vial is rated for 336 hours of run time, giving you weeks of consistent scent before you need a swap.
• Sweet Grace scent profile: Bridgewater Candle's best-known fragrance — warm, lightly powdery, and well-balanced for everyday home use.
• Pura smart diffuser compatible: Designed exclusively for Pura smart diffusers, which offer schedule control, intensity adjustment, and two-vial slots via the Pura app.
• Compact 0.33 oz format: Small footprint that fits neatly into the diffuser without protruding, and easy to store extras without taking up counter space.
• App-controlled intensity: Once inserted and recognized, intensity and scheduling are managed entirely through the Pura app — the NFC handshake just removes the manual step.

Pura smart diffuser refill vials like this one don't require any special maintenance on your part — the vial is sealed and self-contained until it's empty, at which point you simply pull it out and recycle or dispose of it according to your local guidelines. To keep your Pura diffuser itself performing well, wipe the vial slot with a dry or barely damp cloth every few refills to prevent any residue buildup around the sensor contacts. Avoid getting moisture inside the device. Bridgewater Candle Sweet Grace refill vials are designed for single use, so there's no refilling the vial itself — when the 336 hours are up, a fresh vial is the cleanest and most reliable way to maintain consistent scent output from your diffuser.
