Problems solved by technology

[0003] The problem of the air filter in the above-mentioned conventional example is that the life of the air filter is short
That is, the initial collection performance should be improved, but the smaller the fiber diameter of each layer, the more significant the increase in pressure loss due to long-term use, and the user has to replace the air filter every few years.

Abstract

This air filter is provided with a base part (12) and a fiber layer (13) that is arranged on the surface of the base part (12). The fiber layer (13) is configured of a first nanofiber assembly (13a) and a second nanofiber assembly (13b). The first nanofiber assembly (13a) is arranged at the farthest side from the base part (12), and the weight per square meter of the first nanofiber assembly (13a) is higher than the weight per square meter of the second nanofiber assembly (13b). In addition, the first nanofiber assembly (13a) has a larger average fiber diameter than the second nanofiber assembly (13b).

Description

technical field [0001] The present invention relates to an air filter, an air cleaning device having the air filter, and a manufacturing method of the air filter. Background technique [0002] When viewed from the windward side, conventional air filters have an upper layer, a middle layer, and a lower layer in which multiple layers of fibers with large fiber diameters are stacked in order (for example, refer to Patent Document 1). [0003] The problem of the air filter in the above conventional example is that the life of the air filter is short. That is, the initial collection performance should be improved, but the smaller the fiber diameter of each layer, the more prominent the increase in pressure loss due to long-term use, and the user has to replace the air filter every few years.
