How much is the indoor in addition to formaldehyde? How much does a test cost?

200 yuan is tested once, and in addition to formaldehyde is around 500 yuan. At present, the biggest decoration pollution in decoration is formaldehyde, which is quite harmful to people's health. Therefore, appropriate measures must be taken to reduce the content of formaldehyde. Although many products that control formaldehyde are under the banner of "high technology" and "environmental protection", some inferior chemical synthetic substances are used. Although these products can eliminate formaldehyde to a certain extent, they may also produce other pollutants again, leading to secondary pollution. Therefore, consumers must be vigilant when purchasing formaldehyde control products. For example, chemical air treatment products are obtained by artificial synthesis, many of which are aromatic compounds. Almost all aromatic compounds contain benzene ring compounds that have been proved or suspected to be carcinogens. In addition, many chemical products are oxidizing and corrosive, which are easy to damage utensils, as well as operators and residents. When the coating of closed shielding products is aging and the weather is hot and humid, the coating will be easily damaged, releasing harmful substances such as formaldehyde and becoming a hidden "time bomb" in the family.
