Nowadays, many fast-moving families use some fast-moving blue stones at home. Fast blue stone is recently developed successfully, and contains Meen marine purification factor, which truly realizes a new breakthrough of adsorption and decomposition in in addition to formaldehyde. The reason why the research and development of fast-blue stone is a breakthrough of formaldehyde treatment means is that fast-blue stone not only contains the decomposition ability of Meen marine purification factor, but also has the adsorption ability better than that of activated carbon, which turns the theory of "adsorption+decomposition" into reality. Fast blue stone is composed of various mineral components, including Meen marine purification factor and cold catalyst purification molecular beam, which can adsorb and decompose many harmful substances such as formaldehyde, benzene and TVOC.
