Small Low-Cost Air Purifier Controlled by an Android Smartphone

Abstract

Since air purifiers are currently expensive, this research presents a small low-cost Air purifier that is controlled via a smartphone by applying a Voltage Multiplier and a 2-level fan system that is used to control the air flow through the filter, which helps clean the air of particles as small as 0.1 micron. In addition, the proposed system can also be controlled via an application on the Android operating system. The results of an experiment in a closed room with a size of 3.15 and 7.8 square meters that simulated the maximum dust situation at an AQI value of 300 showed that the proposed system can reduce the amount of dust with a level of effectiveness similar to that of an air purifier of the same model, while the cost of the proposed system is lower. In the future, this low-cost air purifier may be added the scheduled On-Off function for easy-to-use.
