Dust often appears to settle in corners due to a combination of factors:
Air currents: Air currents within a room or space tend to flow in a circular pattern. As air moves around, it creates turbulence and eddies, causing particles like dust to be carried along with the air. When the air reaches a corner, the turbulence decreases, and the slower-moving air allows the dust particles to settle.
Lack of airflow: Corners typically have less airflow compared to open areas in a room. The air movement near walls and corners is restricted, leading to reduced turbulence and slower air circulation. With less air movement, dust particles have a greater chance of settling on surfaces.
Gravitational settling: Dust particles are generally not heavy, and they remain suspended in the air for some time. However, due to their small size and mass, they eventually succumb to gravity and settle on surfaces. Corners, being lower in height and often undisturbed, provide a convenient landing spot for these particles.
Reduced cleaning: Corners are often hard to reach and clean thoroughly. They may be neglected during regular cleaning routines or difficult to access with standard cleaning tools. Over time, this can contribute to an accumulation of dust in corners, making it more noticeable compared to other areas.
It's important to note that these factors may vary depending on the specific environment and airflow patterns within a given space. Regular cleaning and maintaining proper ventilation can help minimize the amount of dust settling in corners.
