ENJOY YOUR FAVORITE ESSENTIAL OILS: Made of ecological bamboo wood, it contains a natural organic absorbent which repels water, humidity, bacteria, and mold. This absorbent allows the diffusion of oils to the ambient air, without needing an energy source, such as batteries, electricity or heat. Absorbs and encapsulates essential oils quickly to allow a diffusion which lasts in time, compared to other diffusers with absorbent pads, volcanic beads or clay which do not diffuse very long.
