The rise in global temperature is closely related to greenhouse gas emissions. In the current situation, carbon footprint accounting is particularly important, but its development is not yet sound and it lacks pertinence to industries.

[0003] Air filters are widely used in the construction industry, and their carbon footprint is part of the carbon footprint of buildings. As one of the main objects of carbon reduction and emission reduction, clarifying the carbon footprint of air filters in buildings will play a positive role.
