Inertia and Diffusion

Particulate dust undergoes inertial motion in airflow. When it encounters randomly arranged fibers, the airflow changes direction, and the particles, due to inertia, deviate from their original direction and collide with the fibers, becoming adhered. Larger particles are more likely to collide, resulting in better filtration.

Small particulate dust undergoes random Brownian motion. The smaller the particle, the more intense the random motion, the more opportunities it has to collide with obstacles, and the better the filtration effect. Particles smaller than 0.1 micrometers in the air mainly undergo Brownian motion; smaller particles have better filtration effects. Particles larger than 0.3 micrometers mainly undergo inertial motion; larger particles have higher efficiency. Particles with little diffusion or inertia are difficult to filter. When measuring the performance of HEPA filters, the efficiency value for difficult-to-measure dust particles is often specified.

Small dust particles undergo random Brownian motion. 

The smaller the particle, the more intense the random motion, the more opportunities it has to collide with obstacles, and the better the filtration effect. Airborne particles smaller than 0.1 micrometers primarily undergo Brownian motion; small particles result in good filtration. Particles larger than 0.3 micrometers primarily undergo inertial motion; larger particles have higher efficiency. Particles with little diffusion or inertia are difficult to filter. When measuring the performance of HEPA filters, the efficiency value for difficult-to-measure dust particles is often specified.

Inertia and Diffusion

Distant dust particles undergo inertial motion in the airflow. 

When they encounter randomly arranged fibers, the airflow changes direction, and the particles, due to inertia, deviate from their direction and collide with the fibers, becoming stuck.

Airborne particles smaller than 0.1 micrometers primarily undergo Brownian motion; small particles have good filtration. Particles larger than 0.3 micrometers mainly undergo inertial motion, and the larger the particle, the higher the efficiency. Particles with little diffusion or inertia are difficult to filter out. When measuring the performance of HEPA filters, the efficiency value for dust particles that are difficult to measure is often specified.
