"Dustproof" refers to an object's ability to resist the intrusion of dust particles. This feature is particularly important for electronic devices, cameras, and other equipment that can be damaged or hindered by dust accumulation. Products labeled as dustproof often have seals or protective casings that prevent dust from entering. Many consumer electronics, such as smartphones and laptops, are designed with dustproof characteristics to enhance durability and longevity. The IP rating system, which stands for Ingress Protection, is commonly used to indicate the level of dust resistance, with higher ratings signifying better protection against dust and other particles.
