Fallacy 1: "As long as the filter is cheap and can be installed perfectly on the engine, it's enough

Fact 1: Many domestic filter manufacturers only simply copy and imitate the geometric dimensions and appearance of the original parts, and do not pay attention to the engineering standards that filters should meet, or even do not understand the content of the engineering standards. The design of the filter is to protect the engine system. If the performance of the filter cannot meet the technical requirements and the filtering effect is lost, the performance of the engine will be significantly reduced and the service life of the engine will be shortened. For example, the lifespan of a diesel engine is directly related to the 110-230 grams of dust ingested before the engine is damaged. Therefore, inefficient and low-quality air filters can cause more impurities to enter your engine system, leading to premature engine overhaul

Fallacy 2: "If I don't have to change the filter frequently, then this filter is definitely good

Fact 2: The function of the filter is to filter out dust and impurities in air, oil, fuel, and coolant, keeping these impurities away from the engine and protecting the engine system. High quality and efficient filters are more capable of capturing and filtering out more impurities than inefficient and inferior filters. If the ash holding capacity of both filters is the same, it is obvious that the replacement frequency of high-quality and high-efficiency filters will be higher. Most of the inferior filters sold on the market have a short circuit in the filter element (impurities enter the engine system without being filtered). The reasons for the short circuit are perforation of the filter paper, lack of or weak adhesion between the head and tail of the filter paper, and weak adhesion between the filter paper and the end cover. If you use such a filter, you will not need to replace it for a long time, even for life. Because it has no filtering function at all. Therefore, the above viewpoint is incorrect.

Myth 3: "I don't think the filter I'm using has caused me any trouble, so I don't need to spend more money on high-quality filters

Fact 3: You may or may not immediately see the impact of inefficient and inferior filters on the engine. The engine seems to be running normally, but harmful impurities may have already entered your engine system and started causing corrosion, rust, wear, and other damage to engine components. These damages are implicit and will erupt when the damage accumulates to a certain extent. So, although you don't see any signs now, it doesn't mean that the problem doesn't exist. Like a hidden time bomb. Once a problem is discovered, it may be too late and you will have to spend a lot of money repairing your engine. Therefore, adhering to the use of high-quality and guaranteed filters can provide maximum protection for your engine.

Myth 4: "My engine is already old and out of warranty, so there is no need to use high-quality filters

Fact 4: Old engines are more prone to wear and causing cylinder pulling. Therefore, old engines require high-quality filters to stabilize gradually escalating wear and maintain engine performance. Otherwise, you will have to spend a lot of money on repairs, or you will have to discard your engine in advance.

Myth 5: "The quality of the filter I purchased is a bit poor, but I should replace it regularly without any problems

Fact 5: The quality of a filter is not only measured by its lifespan, but also by its filtration efficiency. High quality filters should have high filtration efficiency and a longer service life. Therefore, legitimate filter manufacturers should fully consider various performance indicators of the filter when designing it. Many filters sold in the market are simple copies and imitations of original parts, and their performance mostly fails to meet the technical engineering standards and specifications of engine manufacturers.

After dissecting, analyzing, and testing the miscellaneous filters in the market, the results were shocking: there were serious leaks and short circuits at the bonding points of the internal filter element's head and tail folds or the bonding points between the filter paper and the end cover. If you purchase and use this filter without filtering function, even frequent replacement cannot effectively protect your engine.
