The filter acts on protecting the engine parts, cleaning and extending the service life of the engine. From the surface of various filters, and the length of time the filter is used, it is not clear whether the filter is good or bad, and the real quality of the filter should be considered comprehensively.
1. Filter paper quality
High-quality filter paper and inferior filter paper, the surface is similar. The quality of the filter paper is related to the efficiency of the filter, the impurities filtered by the high-quality filter paper are more, the inferior filter paper is less, and the protection is not possible, and the related parts of the engine are easy to wear.
2. Filter efficiency
It is mainly determined by the quality of the filter paper used in the filter, and the filtration efficiency of the filter is more than 96%. At the same time and place, the use effect of different manufacturers of filters is not the same, and the obvious difference is that in the process of engine starting and driving, the driver's feeling of the engine and the size of the exhaust smoke, and the wear of the engine parts in the repair are obviously different.
3. Filter paper and end cap bonding material
With high-quality filter paper, there is also a good quality adhesive, such as improper selection, the filter paper in the filter and the upper and lower end caps are not firmly bonded, and the oil is easy to fall off during use, no viscosity, resulting in short circuit, and no filtering effect.
4. Guarantee of filter production process
From the surface, the filter paper can not be adhered to the filter paper, and the light must be seen in the light. If you can not see the light in the light, the adhesion between the filter paper will affect the flow of the entire filter, short life, resulting in insufficient power, weakness, and it is not easy to remove dust during the cleaning process. High quality filter paper does not adhere to each other, has a strong light transmission, suitable for engine intake standards, long service life, easy to clean.
