Anti-Fog Respirator - A simplified explanation of the abstract
This abstract first appeared for US patent application 18356443 titled 'Anti-Fog Respirator
Simplified Explanation
- The patent application describes a respirator that consists of a harness and a mask body. - The mask body is made of air permeable material and has a sinus region and a primary filtering region. - The mask body includes at least one nonwoven fibrous web. - The sinus region of the mask body has a higher resistance to airflow compared to the primary filtering region. - The higher resistance to airflow in the sinus region is achieved by altering the intrinsic structure of the nonwoven fibrous layers without adding any additional material to the mask body. - This alteration of the intrinsic structure helps prevent fogging of eyewear. - The innovation aims to improve the functionality of respirators by addressing the issue of eyewear fogging.
Original Abstract Submitted
A respirator that includes a harness and a mask body that is air permeable. The mask body has a sinus region and a primary filtering region and comprises at least one nonwoven fibrous webs The sinus region of the mask body exhibits a resistance to airflow that is greater than the primary filtering region. This resistance to airflow is achieved through an alteration of the intrinsic structure of the plurality of nonwoven fibrous layers in the sinus region without adding additional material to the mask body. The alteration of the intrinsic structure assists in preventing eyewear fogging.
