WASHABLE FINE DUST FILTER MODULE USING NANOFIBERS
Document Type and Number:
WIPO Patent Application WO/2022/145604
Kind Code:
A1
Abstract:
The present invention relates to a washable fine dust filter module using nanofibers, the filter module comprising: a filter member (10) having a multi-layered structure that includes a nanofiber layer using nanofibers and is corrugated at regular intervals; and a water-repellent treated filter frame (20) for accommodating the filter member (10). The filter module manufactured using the nanofibers according to the present invention can remove fine dust in the nanofiber layer and an MB filter layer, and thus increase filter efficiency. Also, the filter frame is treated so as to be water repellent, and a hot melt coating layer is applied to only a portion of the thickness of the upper and lower sections of the filter member, such that a user can use the filter module by freely and repeatedly washing the filter module with water (a washable function is imparted). In addition, filter performance can be effectually maintained even after the filter module is washed with water, and thus the present invention has the effect of enabling repetitive washing and regeneration.
