Chlorine dioxide can remove formaldehyde. Chlorine dioxide has efficient decomposition and neutralization of toxic and harmful gases such as formaldehyde in the air, and can quickly oxidize and decompose formaldehyde to produce a small amount of carbon dioxide, water and inorganic salts. The free chlorine dioxide ions in the product can be absorbed in the dust in the air and fall down, thus purifying the air.
