The Maison Berger So Neutral refill 1 liter (416012) delivers 40 hours of diffusion and 160 hours of fragrance performance. This 33.8-ounce formulation contains isopropanol as the active ingredient for the catalytic purification process that eliminates odors and refreshes indoor air.

This neutral solution purifies air without diffusing scent and allows you to adjust fragrance intensity by diluting other Maison Berger fragrances. The isopropanol-based formula is classified as highly flammable liquid and vapor that may cause serious eye irritation. Proper handling and storage procedures must be followed for safe use.

Compatible with most Lampe Berger models, this refill works exclusively with Maison Berger Paris catalytic lamps and Air Pur 3P burner systems. Essential for cleaning burners between different fragrances and maintaining optimal lamp performance. Burners should be replaced every 200 uses or annually for best results.
