Formaldehyde is a kind of carcinogen. As early as 1995, formaldehyde was identified as a suspicious carcinogen by the international agency for research on cancer (IARC). In 2004, formaldehyde was identified as a class I carcinogen by the international agency for research on cancer (IARC). In June 2004, the international agency for research on cancer (IARC) of the World Health Organization announced in its publication No. 153 that formaldehyde increased from class II carcinogen to class I carcinogen. Long term exposure to formaldehyde can lead to pathological changes and further cause cancer.

The relevant data show that indoor air pollution is 5-10 times higher than that of outdoor air pollution, and there are more than 500 kinds of indoor air pollutants. Indoor air pollution has become the cause of many diseases, and formaldehyde is one of the main causes of indoor air pollution. Indoor air pollution has great harm to human health, so it is urgent to pay attention to it and control it.
