What Are The Car Filters And How Often Should They Be Replaced?

Car filters are devices that filter out impurities or gases. Common car filters include air filters, cabin air filters, oil filters, and fuel filters. Each type of filter targets 

different impurities, but they generally filter out solid or liquid contaminants. If one of these filters fails, it may cause issues such as unpleasant odors in the car 

or poor fuel performance. Therefore, choosing a good filter is crucial. In today's article, we will introduce the three major filters from NIBD.

How to Distinguish Filters

01 Oil Filter

Function

As a component of an internal combustion engine, the oil filter plays a vital role in the lubrication system. It can remove metal shavings, carbon particles, and 

other impurities that mix with the engine oil during combustion. These impurities can accelerate wear on moving parts and cause blockages in the lubrication 

system. The oil filter ensures the normal operation of the internal combustion engine, significantly extending its service life and the life of other components.

Signs of Failure

- The oil pressure warning light comes on, which may indicate that the oil filter is clogged, resulting in poor oil flow and insufficient oil pressure.

- If the engine produces abnormal noises, it may be due to insufficient oil supply from the oil filter, causing engine component wear.

- If the filter paper or filtering material of the oil filter is severely clogged, it will no longer be able to perform its filtering function effectively.

02 Air Filter

Function

For an engine to operate normally, a large amount of clean air must be drawn in. If harmful substances (such as dust, colloids, aluminum oxide, and iron oxide) 

are inhaled, the cylinder and piston components will be burdened, leading to abnormal wear. These contaminants can also mix with engine oil, causing more 

severe wear and reducing engine performance and lifespan. Additionally, air filters also have a noise-reducing function.

Signs of Failure

- If the air filter is severely clogged, the air intake to the engine will be insufficient, resulting in a rich air-fuel mixture and difficulty in starting the engine.

- A faulty air filter may cause incomplete combustion, leading to black or foul-smelling exhaust gases.

- Abnormal suction sounds from the intake may indicate that the air filter is clogged, causing poor air flow or leakage.

03 Cabin Air Filter

Function

The cabin air filter is used to filter the air inside the car and the air circulating between the inside and outside of the cabin. It removes dust, impurities, smoke, 

pollen, and other contaminants from the air inside the cabin or entering the cabin, ensuring the health of passengers. It also helps prevent the windshield from 

fogging up.

Signs of Failure

- When the cabin air filter is severely clogged, the air resistance through the filter increases, resulting in a significant reduction in the airflow from the air 

conditioning vents.

- If the filter is faulty, such as being heavily contaminated with dust, pollen, or mold, it may produce unpleasant odors, such as musty or dusty smells.

- A clogged cabin air filter can affect the heat exchange efficiency of the air conditioning system, leading to poor cooling or heating performance.
