A SYSTEM AND PROCESS FOR AIR PURIFICATION AND STERLIZATION
FIELD OF DISCLOSURE
[0001] The present disclosure generally relates to filtration system and specifically relates to a system, a device and a process for air purification and sterilization.
BACKGROUND OF THE DISCLOSURE
[0002] Embodiments of the present invention generally relate to a system, device, and process for purification and sterilization of air
[0003] Air pollution has become a pressing global issue, with both indoor and outdoor air quality deteriorating due to industrialization, urbanization, and various human activities. Indoor air pollution, in particular, has gained significant attention because people spend a considerable amount of time indoors, especially in where individuals spend majority of their time indoors.
[0004] Air is the essential medium for respiration, a complex mixture of gases that supports life on Earth. The human respiratory system is designed to utilize oxygen from this mixture; inhaling oxygen and exhaling carbon dioxide in a vital process called gas exchange. While the body requires only oxygen, the presence of other components in the air does not typically harm humans, as our respiratory system has evolved to filter and utilize air effectively.
[0005] However, anthropogenic activities have significantly degraded air quality, leading to pollution. Industrial emissions, vehicular exhaust, and other combustion processes release a plethora of pollutants, including fine particulate matter, composed of substances like anthracene, pyrene, and such. Additionally, the combustion of carbon-based materials generates many harmful gases such as nitrogen oxides, Sulphur dioxide, hydrogen fluoride, and chlorides, which causes damage to the respiratory and cardiovascular systems.
[0006] In addition, the air can also harbor infectious agents like bacteria, viruses, fungi, and prions, which humans can disseminate via aerosol particles or droplets when coughing or sneezing. The intersection of air pollution and airborne diseases represents a dual challenge for public health. While the body's defenses filter many contaminants, prolonged exposure to polluted air can overwhelm these systems, leading to increased susceptibility to respiratory infections and other health complications.
[0007] In indoor air settings, pollutants can originate from various sources, including cooking fumes, tobacco smoke, pet dander, volatile organic compounds (VOCs) emitted from household products, and outdoor pollutants that infiltrate indoor spaces. Prolonged exposure to these pollutants can lead to a wide range of health problems, including respiratory issues, allergies, asthma, and even cardiovascular diseases.
[0008] As a consequence, air purifiers and sterilizers have emerged as popular solutions to improve indoor air quality and mitigate the adverse effects of pollution on health. Particularly, during and after the COVID-19 the demand for improved indoor quality and air sterilization has risen exponentially.
[0009] The primary purpose of air purifiers and sterilizers is to remove contaminants and impurities from indoor air, thereby reducing the concentration of harmful particles and improving overall air quality. These devices employ various filtration and sterilization technologies to achieve this goal.
[0010] High-efficiency particulate air (HEPA) filters are commonly used in air purifiers to capture particles as small as 0.3 microns with high efficiency, including dust, pollen, pet dander, and mold spores. Activated carbon filters are also utilized to adsorb odors, gases, and volatile organic compounds (VOCs), effectively neutralizing unpleasant smells and harmful chemicals.
[0011] Given the increasing prevalence of respiratory disorders and allergies, coupled with growing awareness of the health risks associated with indoor air pollution, the demand for air purifiers and sterilizers continues to rise steadily. These devices have become essential tools for creating healthier indoor environments, especially in homes, offices, schools, and healthcare facilities.
[0012] In a nutshell, the demand for air purifiers and sterilizers has surged dramatically in recent years, driven by growing concerns over air quality and health hazards posed by airborne pollutants. These devices are designed to remove contaminants, such as dust, pollen, smoke, and mold spores, from indoor air, creating a cleaner and healthier environment. However, while air purifiers and sterilizers offer numerous benefits, they also associated with many limitations and challenges.
[0013] The currently available air purifiers and sterilizers vary in their effectiveness depending on factors such as the type of pollutants present, the size of the space, and the efficiency of the device's filtration or sterilization technology. Some pollutants, such as certain volatile organic compounds (VOCs) and gases, may not be effectively removed by standard filtration methods.
[0014] Many of the current air purifiers and sterilizers consume a significant amount of energy, especially models with powerful fans or UV lamps. This can lead to increased electricity bills and contribute to environmental concerns associated with energy consumption, heat emission and carbon emissions.
[0015] In addition, proper and extensive maintenance is essential to ensure the continued effectiveness of air purifiers and sterilizers. Filters need to be replaced regularly according to manufacturer recommendations, which can incur additional costs and inconvenience for users. Neglecting maintenance can result in decreased performance and compromised air quality.
[0016] Further, many air purifiers and sterilizers can generate noise, particularly those equipped with powerful fans or motors. This noise can be disruptive, especially in quiet environments such as bedrooms or offices, potentially impacting sleep quality and productivity.
[0017] Yet another concern is the high cost, the upfront cost of purchasing an air purifier or sterilizer, especially models with advanced filtration or sterilization technologies, can be relatively high. While these devices offer long-term benefits, the initial investment may deter some consumers from adopting them, particularly those with limited budgets.
[0018] Furthermore, the effectiveness of air purifiers and sterilizers is often limited to the area in which they are placed. Larger spaces may require multiple devices or more powerful models to achieve adequate air purification, increasing the overall cost and energy consumption.
[0019] Therefore, there is a need of a system, device, and process for air purification and sterilization
