Abstract

The present invention relates to nanofiber based non-insertable nasal filter. The joint geometry of the nasal filter designed enables easy usability and enables application on nasal periphery in one go. The nasal filter provides multilayer filtration for particulate matter between 2.5PM and 10PM aerosols with high efficiency and may be used in industries, by traffic police, by commuters for daily use and people with pollen allergy.

Description

technical field [0001] The subject matter described herein relates generally to the field of nasal filters. More specifically, the present invention relates to nanofiber based externally administrable nasal filters and methods of making the same. Background technique [0002] Nature maintains a balance between soil, water, air and all living things in the world. Any type of imbalance in the biosphere leads to environmental pollution. Over the past decade, the number of motor vehicles has increased rapidly, causing an increase in air pollution due to exhaust from internal combustion engines. Diesel engine exhaust is a major cause of smog and smog layers in many large towns and cities. [0003] Apart from this, several other reasons for the increase in air pollution levels are rapid industrialization, urbanization, use of motorcycles, agriculture and nuclear energy programmes. Among these, motorcycles using diesel and low-quality gasoline are the main sources of air pollut...
