For the Stadler Form Mia fragrance diffuser, you can use essential oils or fragrance oils specifically designed for aroma diffusers. We recommend using high-quality oils that are compatible with electric diffusers to ensure optimal diffusion and preserve the product's lifespan.

It is important to avoid using oils that could damage the equipment or alter the performance of the diffuser. Recommended oils are generally indicated in the product documentation or on the manufacturer's official website.
