Zusammenfassung:The invention provides a formaldehyde detection method and a formaldehyde detection device, and relates to the technical field of formaldehyde detection.The method comprises the steps that if first concentration information is larger than or equal to a first concentration threshold value, air purification equipment is started; acquiring second concentration information of formaldehyde; according to the first concentration information and the second concentration information, whether the activated carbon filter is replaced or not and whether a chemical formaldehyde removal agent is added or not are determined; determining the dosage of a chemical formaldehyde removal agent and the number of replaced activated carbon filters; after the chemical formaldehyde removal agent is added and the activated carbon filter is replaced, the air purification equipment is started, and formaldehyde concentration information is continuously detected; when the concentration information of the formaldehyde is lower than or equal
