When the formaldehyde content exceeds the standard by 2-3 times, no obvious odor can be smelled, and it may also be masked by other odors. Formaldehyde is a gas that is extremely difficult to volatilize and can stay indoors for as long as 3-15 years.

04Maya blue adsorption

Maya blue is a highly efficient formaldehyde removal material that controls indoor air pollution by adsorption and decomposition. The developed pores of Maya blue can absorb formaldehyde and other pollutant molecules, and then decompose the pollution. The decomposition components in Maya Blue can decompose pollutant molecules such as formaldehyde, benzene, TVOC, etc. into harmless gases commonly found in the air, such as oxygen, carbon dioxide, and nitrogen, and then continue to absorb and decompose, forming a virtuous formaldehyde removal cycle.
