This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,719.

Summary of the Inventive Concept

A versatile filter assembly applicable to various industries beyond medical devices, providing a comprehensive solution for air quality improvement and pathogen removal.

Background and Problem Solved

The original patent, focused on insufflation systems, has limitations in addressing air quality and pathogen removal in other industries. The new inventive concept addresses this gap by applying the core technology to diverse industries, such as aircraft cabins, public transportation, fire suppression systems, greenhouses, and animal husbandry.

Detailed Description of the Inventive Concept

The new filter assembly is designed to capture and remove airborne pathogens and pollutants from various air circulation systems. In the aircraft cabin application, the filter assembly is positioned between the cabin air supply and outlet, ensuring clean air for passengers. In public transportation, the filter assembly is installed in the air circulation system to reduce the risk of airborne disease transmission. Similarly, in fire suppression systems, the filter assembly removes impurities from the fire suppression agent. In greenhouses, the filter assembly captures and removes airborne pollutants and pathogens from the ventilation intake, improving indoor air quality. In animal husbandry, the filter assembly reduces the risk of airborne disease transmission in animal enclosures.

Novelty and Inventive Step

The new inventive concept is novel in its application of the original filter assembly technology to diverse industries, providing a non-obvious solution for air quality improvement and pathogen removal. The inventive step lies in the recognition of the filter assembly's versatility and its potential to address air quality and pathogen removal challenges beyond medical devices.

Alternative Embodiments and Variations

Alternative embodiments may include adapting the filter assembly for use in other industries, such as HVAC systems, industrial processes, or food processing facilities. Variations may include modifying the filter medium, housing design, or incorporating additional features, such as sensors or monitoring systems, to enhance performance and efficiency.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in various industries, including aerospace, transportation, fire safety, agriculture, and animal health. The target market includes companies and organizations seeking to improve air quality, reduce the risk of airborne disease transmission, and enhance overall safety and well-being.
