[0002] The static pressure box is used to control and purify the toxic gas or other gas and dust in the air duct, aiming to provide a stable and safe air environment to ensure human health and safety. Its main function is air filtration and purification. The air filter can remove most of the noise, particulate matter, viruses, fungi and other pollutants to achieve the effect of cleaning and purification.

[0003] The filter screen of the static pressure box in the prior art is difficult to disassemble and replace, resulting in poor purification efficiency when the static pressure box is used for a long time, and the connection is not tight, which will cause unfiltered air to drill out from the connection.
