Fireless aromatherapy volatilizes natural plant essential oils containing micro-oxygen through a special constant-temperature vaporization core. It not only produces sufficient fresh pure oxygen, but also releases a large amount of ozone and fragrance. Polyspermine, negative ions and plant aromatic molecules make our polluted environment fresh and healthy. At present, fireless aromatherapy has become the first choice for many countries in the world in purifying the air, improving environmental sanitation, preventing diseases, enhancing physical fitness, regulating brain function and protecting olfactory function, and is becoming popular all over the world.
