“…[ 6 ] Due to those reasons, commercial purifiers usually consume enormous amounts of energy and operate under high‐voltage high‐power condition, posing safety risks. [ 7,8 ] To address these issues of energy consumption and safety concerns, there is an urgent need for a new generation purifier that offers self‐powering capabilities, simplicity, and enhanced security.…”

Human health and the environment face significant challenges of air pollution, which is predominantly caused by PM2.5 or PM10 particles. Existing control methods often require elevated energy consumption or bulky high‐voltage electrical equipment. To overcome these limitations, a self‐powered, convenient, and compact direct current high‐voltage triboelectric nanogenerator based on triboelectrification and electrostatic breakdown effects is proposed. By optimizing the structure‐design of the direct current triboelectric nanogenerator and corresponding output voltage, it can easily achieve an output voltage of over 3 kV with a high charge density of 320 µC m−2. A power management circuit is designed to overcome the influence of third domain self‐breakdown, optimize 92.5% amplitude of voltage shake, and raise 5% charge utilization ratio. With a device size as tiny as 2.25 cm3, it can continuously drive carbon nanowires to generate negative ions that settle dust within 300 s. This compact, simple, efficient, and safe high‐voltage direct current triboelectric nanogenerator represents a promising sustainable solution. It offers efficient dust mitigation, fostering cleaner environments, and enhancing overall health.

“…Electrostatic and sleeve filters are the most commonly applied devices in world practice due to high efficiency in removing particulate matter (PM) from the air. However, they are expensive and rather difficult to maintain [1][2][3][4]. Centrifugal filter is a kind of industrial equipment used for gas (air)-PM separation in thermal power plants, fluidized bed combustion processes, control of air pollution as well as for sorting/sieving materials [5].…”

The main aim of this investigation was an experimental analysis of the air cleaning efficiency in a mock-up next-generation air cleaning device - one-level 8-channel industrial cyclone-separator with quarter-rings - while changing parameters of the inner structure and the assessment of the effects of dispersion of particulate matter. Therefore, the research was carried out in two stages: the first stage covered the analysis of the efficiency of the multi-channel cyclone with particulate matter of <20 and <50 ?m. During the second stage, a cascade impactor was used to measure the particle collection efficiency in the multi-channel cyclone by fractions: PM1, PM2.5 and PM10. Results of the tests with using the cascade impactor were compared to show changes in the PM composition before and after the multi-channel cyclone-separator. According to the obtained experimental data, the one-level 8-channel cyclone-separator collects 70 to 80 % of PM up to 10 ?m in size, 45 to 60 % of PM up to 2.5 ?m in size and 21 to 25 % of PM up to 1 ?m in size.
