Abstract:
The worsening air quality has become an environmental issue since it has a serious effect on human health. This is generally attributed to airborne particles including various pathogens and others fine particles. Even though air filters show excellent removal efficiency towards pathogens, the captured microorganism can remain viable in the filter, grow, and re-suspended into an air stream resulting in a secondary source of pollutants. Considerable studies have been conducted to develop air filters which also have antibacterial properties for solving this issue. Results of several studies showe

Abstract:
A laboratory study was conducted to evaluate 11 vehicular cabin filters (including electrostatic filters) in removing fine particles. Two filters with charcoal were also evaluated to understand their usefulness in removing five common volatile organic compounds, including benzene, toluene, ethylbenzene, and xylene isomers (BTEX). Filters were found to show considerably different particle filtration efficiencies (FE). Electrostatic filters were found to provide 20–60% better FE across all particle diameters (6–520 nm). For 6 nm particles, FE from 78 to 94% were observed (from the worst to the b

Pollution is increasing very effectively in the world. It must be reduced the present pollution levels by the deadline even though the long-term solution to the pollution problem is to identify and reduce pollution sources. The use of air purifiers is the most effective method of reducing pollution. Regular interior air purifiers, however, are little, low-power gadgets that lack the necessary filtering capacity for outdoor environments. Additionally, there is a problem with outdoor machines' power supplies. Therefore, it has created a solar outdoor air purifier that is energy independent and b

Improving indoor air quality through the use of air purifiers has become a major focus, with emphasis on developing filters with high efficiency, high holding capacity, and low-pressure drop to improve the clean air delivery rate (CADR) for air purifiers.

In recent years, because of outdoor ultrafine particles, residential heat recovery ventilators (HRVs) have been used with high efficiency filters by residents in Korea. However, as pre-filters are primarily used in residential HRVs, when a high-efficiency particulate air (HEPA) filter is installed, the filter pressure drop increases, reducing the airflow rate, which requires the fan to draw more power to maintain the airflow rate. Therefore, in this study, the change in power usage of HRVs installed in residential apartments in Korea with various air volumes and filters were analyzed. The resu

Abstract: Air purifier filters utilize fine sieves that filter particles out of the circulating air. As air flows into the air purifier, the finer the sieve inside of the air purifier, the smaller the particles it will trap. High Efficiency Particulate Air (HEPA) filters are the benchmark for air purifier filters, which are guaranteed to trap 99.97% of airborne particles larger than 0.3 microns in size. Microns are the standard unit that is used to measure the size of particles in the air. Each micron is equivalent to 1/25,400 of an inch. The naked eye cannot see anything that is smaller than

Filtration is applied to the inlet air to provide protection against the effects of contaminated air.

As part of the commercialization effort, SWPC has been actively involved in the development of advanced filter materials and component configuration, has participated in numerous surveillance programs characterizing the material properties and microstr

Abstract:
The newly developed depth-loading filter types MaxiPleat filter and depth-loading filter cartridge offer gas turbine users numerous advantages in terms of clean air quality in the combustion air, cost-efficiency due to favourable pressure drop, long life and high functional reliability over the entire operating period. The MaxiPleat filters fitted with a paper-like filter medium are produced by using the patented thermal embossing process, distinctive for its solution to the spacing problem. Without using any foreign materials as separators, depths of 250 mm can be achieved in pleating, with V

Abstract:
We built a collector to filter interplanetary dust particles (IDPs) larger than 5 µm from the clean air at the Amundsen Scott South Pole station. Our sampling strategy used long duration, continuous dry filtering of near-surface air in place of short duration, high-speed impact collection on flags flown in the stratosphere. We filtered ~107 m³ of clean Antarctic air through 20 cm diameter, 3 µm filters coupled to a suction blower of modest power consumption (5–6 kW). Our collector ran continuously for 2 years and yielded 41 filters for analyses. Based on stratospheric concentrations, we predic

Abstract:
Development of high efficiency particulate air (HEPA) filters demonstrate an effort to mitigate dangerous aerosol hazards at the point of production. The nuclear power industry installs HEPA filters as a final line of containment of hazardous particles. An exploration of analytical, experimental, computational, and machine learning models is presented in this dissertation to advance the science of air filtration technology. This dissertation studies, develops, and analyzes alternative air filtration materials and methods of analysis that optimize filtration efficiency and reduce resistance to

Abstract:
Inlet air filters are widely used to remove solids and liquid droplets from the ambient air before it enters the compressor of a gas turbine. Clean inlet air provides many advantages: Less corrosion of the compressor and of gas-path hot parts, such as the turbine, decreased compressor fouling, less erosion of the compressor bladeThese in turn prevent deterioration of output and heat rate, and reduce maintenance costs. Compressor fouling is caused by the ingestion of substances that deposit and adhere to blade surfaces, resulting in reduced aerodynamic efficiency and decreased available output.
