A new air PM2.5 filtrative lamp with a combination of fabric filter and TiO2 coating mop

Abstract

Abstract Air particle cleaning in developing countries in Southeast Asia has become important especially regarding local respiratory health. One of possible solutions is air filtration which is normally used but at high cost. Therefore, this study aims to develop low cost air PM2.5 filtration using integrated lamp, and then investigate filtration performance of adaptive lamp. The integration of fabric filter and floor lamp is designed with fan unit driving force, and then photocatalytic process is applied for increasing air purificative performance. Tests are set in 2.5 m width × 2.5 m length × 2.5 m height bedroom within three regimes: (A) existing filter, (B) integrating fabric filter lamp and (C) adapting TiO2 fiber mop to filter lamp. Based on EPA standard, no regime examined exceeds NAAQs at 35 μg/m3, while regime C with fan speed 2 m/s shows the best performance of air purification. Then the MERV level of filtrative lamp demonstrates MERV15 and MERV16 to identify regime B lamp with 3 m/s fan speed and C lamp with 2 m/s fan speed respectively.
