The reduction percentage inside the mass concentration of PM10 connected with incense and candle smoke after the deployment of AP I was 29.fourteen. This is certainly incomparable to the analyze by Butz et al. (2011) wherein HEPA air purifier was operated in presence of ETS. No therefore craze in reduction percentage (in mass concentrations of PMs) following deployment of AP II in candles and incense smoke was noticed as acquired in AP I.
