Winter Noir

All Pura fragrances are compatible with every Pura diffuser model, including the Pura 4, Pura 3, Pura Plus, and Pura Car.

Each fragrance vial lasts approximately 350 hours of use depending on your intensity settings and room size.

Fragrance longevity can vary slightly between diffuser models due to differences in airflow and diffusion technology, but all models are designed to provide consistent, long-lasting fragrance.

To extend your vial's life, consider lowering the intensity setting, scheduling fragrance-free hours, and placing your diffuser in a smaller room.

We recommend choosing a frequency that aligns with your usage. Most customers find that a monthly or bi-monthly subscription works best depending on their intensity settings.

Use two complementary fragrances and schedule them to alternate throughout the day, or assign different scents to different times — one for morning freshness and another for evening relaxation.

Your Pura app will notify you when a vial is running low. You'll also notice a decrease in fragrance intensity as the vial nears empty.

Most Pura users run their diffuser for 8–12 hours per day at medium intensity, which provides consistent whole-room fragrance coverage.
