IoT Air Purifier with Humidification Function Capable of Removing PM1.0 Ultra-fine Dust

Abstract

Recently, as the atmospheric environment is getting worse due to yellow dust and fine dust, which has a lot of influence on daily life, people's interest in air purifiers is growing. In this paper, as part of the research on air purifiers, we design an air purifying humidifier that integrates PM1.0 level ultra-fine dust removal function and natural humidification function into one. The air purifying humidifier designed in this paper uses a sensor that detects PM1.0 level ultrafine dust, and the number concentration is 95% similar to that of the reference measuring instrument. Also, by mixing the resin on the surface of the motor fan, it is possible to antibacterialize the bacteria remaining in the air even after passing through the filter. As a result of the test, more than 99% of the bacteria were removed after 6 hours of artificial incubation. In addition, it is designed to sterilize using hydroxyl generated by electrolysis of water to remove bacteria mainly generated due to the structure of the humidifier.
