47cm wick length.
This is the best catalytic burner ever produced. It sips oil sparingly, releases more fragrance, reveals very subtle fragrance notes, and cleans the air more efficiently than the old Lampe Berger burner.
The new Air Pur System 3C wick/burner is on the cutting edge of technology; the result of 5 years of research, offering improved performance. The new model guarantees improved fragrance diffusions with a higher intensity, more rapid elimination of odors (67% quicker!), optimal elimination of airborne bacteria, improved ease of use (you can now use your lamp when completely full), and reliable and optimal performance thanks to the skillful use of the synthetic ceramic material.
