In terms of basic concepts贝格富, the size of an efficient filter usually refers to the length贝格富, width and height of its outer frame. Taking the common unbarriered efficient filter as an example, the common specifications on the market include 610x610x69mm, etc. Here, the first two numbers represent the length and width of the filter's outer frame, and the third number represents its thickness. And the filtration area is not simply equivalent to the appearance area of the filter; it mainly refers to the effective area of the filter material that actually participates in the filtration process.

Plateless high-efficiency filters use ultra-fine glass fiber filter paper or polypropylene filter paper as the filter material, and use cardboard, aluminum foil, etc. as partition plates. Due to the presence of the partition plates, the filter material is divided into multiple small filtration units. The same is true for plateless high-efficiency filters, which use hot melt glue or polyurethane glue instead of partition plates, and the outer frame is usually aluminum alloy profiles, wooden frames or galvanized sheets.
In a plate-type high-efficiency filter, its structural characteristics determine the relationship between size and filtration area. Plate-type high-efficiency filters use ultra-fine glass fiber filter paper or polypropylene filter paper as the filter material, and use cardboard paper, aluminum foil, etc. as partition plates. Due to the presence of the partition plates, the filter material is divided into multiple small filtration units. From an actual application perspective, different sizes of high-efficiency filters are suitable for different scenarios, and this is also based on the relationship between filtration area and size. In some places with high space requirements, such as FFU (Fan Filter Unit), plateless high-efficiency filters are often used. Their compact size (such as a thickness of 69mm) ensures sufficient filtration area through reasonable design of the folding method of the filter material within the limited space. In large central air conditioning systems or centralized air supply systems of industrial clean rooms, due to the relatively spacious space and high air volume requirements, larger plate-type or plateless high-efficiency filters (such as a size of 1220x610x220mm) with partitions are selected. Their larger size enables the filter material to have a larger unfolding area, forming more filtration units, thereby providing a larger filtration area to meet the requirements of high air volume and high cleanliness for air purification.
The filtration area of an efficient filter is related to its size. The size not only determines the space available for arranging and unfolding the filter material贝格富, but also affects the folding method and the number of pleats of the filter material, thereby determining the size of the filtration area. When choosing and applying efficient filters in practice, fully understanding this relationship can help us accurately select the appropriate efficient filter according to different usage scenarios and requirements, to achieve better air purification effects.
