In order to Maximize engine efficiency, users should control the working environment of engine, keep the air and oil inside engine clean. High-quality filters are crucial to the reliability, safety and service life of engine. With the popularization of National III emission standard, engines have higher requirements towards filters. But there’s still misunderstanding from some sellers and users.

Misunderstanding#1:

“It’s fine for filters as long as they are cheap and can fit perfectly into the engine.”

The truth: Numerous manufacturer in our country just copy and imitate the dimension and appearance of the original simply. They don’t take the engineering standard which filters should match into account and even don’t know the content of engineering standard. The purpose of filter is to protect the engine system. If filters can’t meet the technical requirements and lose the filtration effect, the performance of engines will decrease observably. Then the service life of engine is shortened and large repairment is coming earlier.

Misunderstanding#2:

“Filters with longer service life are better. “

The truth: The function of filters is filtering the dust and impurities in air, oil, fuel and keeping impurities away to protect the engine. High quality and efficient filters will filter more impurities than low efficiency filters. If the capacity of dust volume of 2 filters are the same, it’s obvious that the more efficient filter has shorter service life. Some inferior filters in the selling market can’t achieve filtration effect due to poor production technique. If using such filters, you won’t need to change the filter for a long time or even forever.

Misunderstanding#3:

“I think the filter I’m using doesn’t bring any trouble for me. So it’s not necessary to pay more for buying a high quality filter. “

The truth: You may not see the influence on engine made by inferior and low efficiency filter at once or even ever. The engine seems working well, but harmful impurity possibly has entered your engine system long ago and started causing corrosion, rusting, abrasion to your engine parts. The damage is invisible and will burst out when it goes to a certain extent. Therefore, even you can’t see any signs, the problem is existing indeed. Once the problem breaks out, it’s already too late and you will have to pay a lot to repair the engine. Therefore, keeping using high quality filter will protect your engine to the full extent.

Misunderstanding#4:

“My engine is old and exceed the guarantee period. So it’s not necessary to use high quality filters.”

The truth: Old engines have more abrasion and scuffing of cylinder bore. High-class filters can slow down the increasing abrasion and maintain the performance of old engines. Otherwise, users have to pay large maintenance cost or even scrap the engines earlier.

Misunderstanding#5:

“The quality of the filter I use is not good, but there won’t be problems if I often replace it with a new one.”

The truth: As the measurement indicators of filter’s quality, filter effect is more important than service life. Good filters should have both high efficiency and long service life. So the manufacturers of high quality filters take various performance indicators into full consideration when designing the product. Numerous filter products in market just simply copy and imitate the original and mostly can’t meet the standard specification requirement for technical engineering of engine manufacturers.
