Performance Evaluation of Domestic Ionizer Type Air Cleaners

Abstract

Dust pollution is a serious indoor health problem in domestic premises. Many households are using portable home air cleaners to remove indoor air pollutants. Ionizer type air cleaners are the most popular in the market and dust is one of the common airborne pollutants in indoors. The performance of dust removal efficiency of ionizer type air cleaners is an important domestic indoor air quality (IAQ) issue. There are various kinds of household dust produced. They have different impacts on occupants' health. This study focuses on the effect of different dust aerodynamic diameters (PM10 and PM2.5) and critically reviews the methods and parameters influencing the performance of an ionizer type domestic air cleaner for removing dust. The performance test was conducted in an airtight test chamber. The study was performed to develop a mathematical model to assess effectiveness of air cleaners. Experimental results were analyzed to determine whether the use of the air cleaners could significantly reduce dust pollution and the CADR of each air cleaner.
