Let me talk to you again about the impact of wind speed on air filters. In general, the slower the wind speed, the better the effect of the air filter. The diffusion effect of small particle dust is very obvious. If the wind speed is low, the air can stay in the filter material for a longer time, and the dust in the air is more easily captured by the air filter.
If the filtering material has static electricity, the longer the dust passes through the air filter, the greater the possibility of adsorption. So wind speed has a significant impact on the quality and efficiency of air filters!
For large particulate dust in the air, due to its high inertia, the probability of dust colliding with filter cotton decreases when the wind speed decreases, resulting in a decrease in efficiency. On the contrary, if the wind speed is higher, the resistance will be greater. Resistance has a significant impact on the service life of air filters, and the greater the resistance, the lower the service life of the air filter. This phenomenon is difficult to observe in practice, but it is much easier to observe the effect of wind speed on resistance.
