Then, the vacuole attached with the micro-particles has larger particle size, and the approaching speed is in direct proportion to the particle size:

approaching speed:

w＝qE/(3πμd)

q- -amount of charged particles

E- -electric field intensity

μ - -air viscosity (kg/(ms))

dp- -particle diameter

Higher approaching speed, easier collection by the dust collecting plate and clean particulate matters.
