Formaldehyde, as a common indoor air pollutant, has serious harm to human health. Therefore, the research and development of multifunctional formaldehyde purification devices has important practical significance.

[0003] Formaldehyde mainly comes from decoration materials, furniture, paint, glue, etc. It has a pungent odor.
