Why choose a filter with a large effective filter area?

What is the effective filtration area? It is the actual area of the airflow filter material.
Apart from a small number of low-efficiency filtration devices, the effective filtration area of most devices is several, tens, or even a hundred times the airward side of the device.
Because most of the captured dust pollution is concentrated on the windward side of the filtration equipment, the larger the effective filtration area, the greater the amount of dust the equipment can hold and the longer the life of the equipment.

And after a series of practices can also prove that a reasonable increase in the effective filtration area is a good way to extend the service life of the equipment, for the same structure and filter media filtration equipment, when its final resistance is determined, the area of the filter media will increase by 50%, the service life will also be extended by 70% - 80%, and the original service life compared to about three times.

As we all know, the more filter media used in the equipment, the higher the price of the equipment, but the increase is certainly such as the effective extension of the use of the equipment, and, with an increased effective area, the initial resistance will also be reduced, so that the energy consumed will also be reduced. Therefore it is certainly beneficial for the user to choose a device with a large effective filter area.

For example, a bag filter can increase the number and length of its filter bags; a conventional filter with a partition can increase the number of pleats of filter paper by reducing the spacing of the partitions; and for projects under design, it is better to choose a design that can accommodate more filter material.
A design that can accommodate more filter material is sufficient.

In summary, we can obtain that the choice of equipment with a large effective filtration area is certainly beneficial to the effect of filtration, but it is not arbitrary to carry out or to consider the possibility of increasing according to the structure of the equipment and the conditions of the site.
In modern times, with the use of various high-efficiency equipment, such as activated carbon filters and so on, we have to be clear about the performance of its use to increase.
