• Choose a filter with a larger effective filtering area

      1. The larger the filter material area, the larger the dust holding capacity, and the longer the service life of the filter

      2. If the effective area is large, the surface velocity will be small, and the resistance loss of the filter will be small

      3. Experience has shown that increasing the effective area by 50% can double the lifespan of the filter, and doubling the effective area can increase the lifespan of the filter by 3-4 times compared to before

• Compare fiber diameter and coarse filtration performance

      1. Fine fibers result in a higher number of fibers per unit volume, leading to higher filtration efficiency

      2. With more fibers, the filter material can hold more dust per unit area, resulting in a longer lifespan of the filter

      3. With more fibers, the gaps between fibers are small, and the branched structure formed by dust is firm, reducing the possibility of secondary pollution caused by dust being blown away

      4. Coarse fibers have high resistance, while fine fibers have low resistance

• Choose a filter with a larger effective filtering area

      1. Two filter materials with the same thickness and fluffiness, fine fiber filter material has high filtration efficiency and large dust holding energy

      2. Two filter materials composed of different fibers with the same efficiency, with low resistance for fine fiber filter materials and high weight for coarse fiber filter materials

      3. Filters made of fine fiber filter material have high efficiency, low resistance, and long service life, but they are expensive and have low strength

• Reusable and disposable filters

      1. The filter material of the washable filter should be strong and the fibers should be coarse, with a diameter generally between 10-50um

      2. Metal mesh and nylon mesh filters can be cleaned, but the filtration efficiency will not exceed G2

      3. Filter materials made of fibers with a diameter less than 5um are generally not washed

      4.The fiber diameter of F6-F8 filters is between 0.5-5um

      5.After passing through the water, some of the dust on the windward side of the filter material is transferred to the exhaust side, and when reused, the filter becomes a source of dust
