A review of portable air cleaner devices: purification processes, performance standards, effectiveness in controlling indoor air pollutants
Background and objective: Indoor air pollutants are among the five most important environmental health risks. In recent years, concerns regarding indoor air in buildings have increased. In this review, studies conducted on portable air cleaners have been investigated. Materials and methods: After determining the keywords and conducting comprehensive searches in the internet databases, taking i...
متن کاملControlled clinical studies of air pollutant exposure: evaluating scientific information in relation to air quality standards.
In controlled clinical studies, volunteers are deliberately exposed to specific air pollutants under conditions simulating ambient exposures, and health-related responses are documented. Studies of the health risks of air pollution need to be scientifically rigorous and clearly relevant to "real-world" pollution exposures. Their results should be confirmed by independent replication if they are...

متن کاملRapid on-site air sampling with a needle extraction device for evaluating the indoor air environment in school facilities.
A rapid on-site air sampling technique was developed with a miniaturized needle-type sample preparation device for a systematic evaluation of the indoor air environments in school facilities. With the in-needle extraction device packed with a polymer particle of divinylbenzene and activated carbon particles, various types of volatile organic compounds (VOCs) were successfully extracted. For eva...
متن کاملIndoor Air Quality
The issues of indoor air quality are complex and can be directly influenced by a number of system and building parameters. There are no universal solutions for every problem since there are numerous potential contaminant sources. They may originate from indoors and have a direct impact on indoor environmental quality, or they may originate from outdoors and be transferred by a mechanical or nat...
