Description
What is a car air filter?
The air filter is an essential component for protecting the engine from contamination. It effectively reduces wear on the cylinders, pistons, and piston rings by removing dust and sand from the air. This helps extend the engine’s service life. The air filter ensures that the air entering the engine is clean, which in turn improves fuel efficiency, reduces emissions, and maintains the engine’s optimal performance.

The air filter is situated under the hood of the vehicle in front of the engine. Stand in front of the vehicle, facing the engine, and then turn to the right. You will see an air filter box, typically fastened with a few screws. Use the right tool to loosen these screws, and you will be able to access the air filter.
What is the function of a car air filter?

- Protecting engine components: the air filter acts as a “mask” for the engine, preventing dust, sand, and other tiny particles from entering the engine. These particles could scratch the cylinder walls, pistons, and piston rings, leading to accelerated engine wear and performance decline. an air filter ensures that the engine operates in a clean environment, thereby extending its service life.
- Enhancing fuel efficiency: when the engine uses clean air, fuel can burn more effectively. This is because clean air can mix better with fuel, forming an ideal air-fuel ratio, and increasing combustion efficiency. This not only improves the vehicle’s power performance but also helps to reduce fuel consumption and save operating costs.
- Reducing environmental pollution: the air filter captures unburned carbon particles and other pollutants that could be emitted with exhaust gases, reducing the adverse impact on the environment. This helps not only to reduce emissions but also to improve air quality and protect public health.
- Easy maintenance: compared to other engine maintenance tasks, cleaning and replacing the air filter is a relatively simple and low-cost operation. Regularly performing this maintenance can prevent early engine failures, maintain its optimal performance, and significantly extend the engine’s service life.
- Improving engine performance: by ensuring the cleanliness inside the engine, the air filter helps the engine reach its designed performance level. This means the vehicle can provide better acceleration, higher horsepower, and an overall better driving experience.
- Reducing repair costs: although the air filter itself is not expensive, it plays an important role in preventing costly engine repairs. By reducing engine wear and extending its service life, the air filter helps to reduce long-term maintenance costs.

CALEPH-Air Filter Introduction
The CALPEH brand air filter utilizes filter paper processed with precision pleating technology. This increases the filtering area and improves filtering efficiency, while also reducing resistance to airflow. The specially processed filter paper is designed to effectively intercept particulate matter ranging from 0.1μm to 60μm while maintaining high-volume air permeability.
The structural design of the filter takes into account various environmental conditions, ensuring its stability and durability under extreme temperature and humidity changes. During manufacturing, the pressing and folding of the filter paper are precisely controlled to ensure the neatness of the filter material and the maximization of filtering effectiveness.

The filter uses high-strength, high-elasticity sealing materials, providing a lasting and secure seal. The long-term elasticity of this material maintains the structural integrity of the filter, ensuring that it continues to perform at its best regardless of environmental conditions or prolonged use. These characteristics make CALPEH air filters highly suitable for continuous or heavy-duty use, providing reliable protection for the engine and extending its service life.

Recommended time to replace air filter
The typical guideline for air filter replacement in automobiles is to perform it after a driving range of 10,000 to 20,000 kilometers. However, the necessity for replacement can fluctuate based on the air quality and environmental conditions encountered during driving. For example, in regions with poor air quality or high dust levels, it’s advisable to replace the air filter every 5,000 to 10,000 kilometers. In contrast, in areas with cleaner air, the time between replacements can be suitably extended.
Especially under certain conditions such as frequent driving near construction zones or in dusty environments, the air filter tends to collect dust and impurities at a faster rate. This accelerated accumulation justifies a more frequent replacement schedule to ensure the engine’s optimal functioning. In cases where the air filter is compromised due to extraordinary circumstances like water exposure, an immediate replacement is essential to avert potential engine damage.

To maintain the engine’s peak performance and longevity, car owners are encouraged to adhere to the manufacturer’s guidelines and recommendations. It’s also important to consider the specific driving conditions when planning the air filter replacement schedule. Compatibility with the engine model is paramount when selecting a new air filter. Using an inappropriate filter can lead to decreased engine performance or even cause damage.
Moreover, it’s beneficial to visually inspect the air filter during regular maintenance checks. If it appears excessively dirty or clogged, it’s a clear indication that a replacement is due. A well-maintained air filter not only safeguards the engine but also contributes to better fuel efficiency and reduced emissions, aligning with environmental sustainability goals.
