“…The pollution from household cooking explains household PM 2.5 exposure to residents, especially household wives, worldwide. Previous studies widely discussed the differences in emission of PM 2.5 between types of fuels, 13,101,102 cooking styles, 98,102,103 and protection strategies 103,104 . Protective measures such as opening range hood and opening windows during cooking time are effective for reducing residents' exposure to household PM 2.5 .…”

Household fine particulate matter (PM2.5) pollution greatly impacts residents' health. To explore the current national situation of household PM2.5 pollution in China, a study was conducted based on literature published from 1998 to 2018. After extracting data from the literature in conformity with the requirements, the nationwide household‐weighted mean concentration of household PM2.5 (HPL) was calculated. Subgroup analyses of spatial, geographic, and temporal differences were also done. The estimated overall HPL in China was 132.2 ± 117.7 μg/m3. HPL in the rural area (164.3 ± 104.5 μg/m3) was higher than that in the urban area (123.9 ± 122.3 μg/m3). For HPLs of indoor sampling sites, the kitchen was the highest, followed by the bedroom and living room. There were significant differences of geographic distributions. The HPLs in the South were higher than the North in four seasons. The inhaled dose of household PM2.5 among school‐age children differed from provinces with the highest dose up to 5.9 μg/(kg·d). Countermeasures should be carried out to reduce indoor pollution and safeguard health urgently.

“…Both models use the light-scattering method to measure the indoor PM concentration, but the costs differ by more than 10 times. While AM510 is already used by numerous studies owing to its verified accuracy and reliability, TES-5322 has not been frequently used despite its economic efficiency [ 25 , 26 , 27 , 28 ]. The measurement accuracy of TES-5322 is below ±5 μg/m 3 when the PM 2.5 concentration is less than 50 μg/m 3 and below ± 10% when the PM 2.5 concentration is greater than 50 μg/m 3 .…”

With the industrialization and rapid development of technology that can measure the concentration of pollutants, studies on indoor atmosphere assessment focusing on occupants have been recently conducted. Pollutants that worsen indoor atmosphere include gaseous and particulate matter (PM), and the effects and diffusion characteristics that influence indoor atmosphere vary depending on the indoor and outdoor concentration. White dust is a PM generated from minerals in water used for humidifiers during winter. Therefore, studies on the impact of white dust on human health and its size distribution are being actively conducted. However, since the indoor PM concentration varies depending on the humidification method and water type used, relevant studies are needed. Accordingly, this study examined the change in the PM2.5 concentration and relative humidity on the basis of water types and humidification method. It was found that the indoor PM2.5 concentration varied from 16 to 350 ug/m3, depending on the water types used for an ultrasonic humidifier. Conversely, when using a natural evaporative humidifier, white dust did not increase the indoor PM2.5 concentration, regardless of the mineral content of the water used. Considering both humidification ability and continuous humidifier use indoors, water purifier with nano-trap filters must be utilized for ultrasonic humidifiers.

“…They found a wide range in the capture efficiency from <15% to 98% [21][22][23][24]. Zhao et al evaluated the efficacy of multiple intervention strategies, including range hood, face mask, personal portable fan, and air cleaner, to reduce PM2.5 exposure in a Chinese kitchen [25]. They found that using a range hood with an equivalent air exchange rate of 7.5-10.9 h -1 and wearing a face mask during cooking reduced 90-95% and 79-84% PM2.5 exposure for the cook, respectively [25].…”
