Description

technical field [0001] The present application relates to the technical field of air purification equipment, in particular to a filter screen based on formaldehyde purification function. Background technique [0002] With the progress of society and the improvement of people's living standards, people have put forward higher requirements for the quality of life. People's purchase of houses, room decoration, and the application and promotion of petroleum, coal, natural gas, chemical products, automobiles, etc., have brought a certain degree of pollution to our indoor and outdoor air while improving our living standards, especially in recent years. With the increasing luxury, the indoor and outdoor air pollution caused by the extensive use of household chemicals, smoking, cooking and other human activities can no longer be ignored, and the quality of the environment directly affects people's health. However, traditional filter materials have been unable to meet people's requi...
