Design a small and portable air filter using a USB fan and simple materials to reduce indoor dust and improve air quality. My solutions is to attach a USB fan to pull air through the layers to trap dust particles. The system  equipped with a dust sensor (for example, GP2Y1010AU0F or similar) outside the system to measure dust levels inside room real time . Connect the sensor to a microcontroller (like Arduino) to display air quality readings. This allows users to see how effective the filter is while improving indoor air quality.
