Universal Automotive Cabin Filter for Activated Carbon Air Conditioner Cabin Filter 87139-06020 used for Chevrolet Cadillac

1. Efficient filtration: Using multi-layer filtering materials such as HEPA (High Efficiency Particulate Air) filters, it can effectively intercept and remove dust, pollen, bacteria, and other particles from the air, providing cleaner indoor air.
   2. Low flow resistance: Design optimization ensures efficient filtration while minimizing air flow resistance, without affecting the normal operation and cold air output of the air conditioning system.
   3. Durability: Using high-quality materials, it has better durability, can cope with various weather and driving conditions, and has a long service life.
   4. Activated carbon adsorption: Some high-performance filters are equipped with activated carbon, which can adsorb harmful gases and odors in the air, improving the air quality inside the car.
   5. Waterproof and oil proof: prevent rainwater and oil stains from entering the air conditioning system, protect the air conditioning components, and reduce maintenance needs.
   6. Easy to replace: The design is simple and easy for car owners to replace on their own, without the need for professional tools or a lot of time.
   7. Strong adaptability: Suitable for various car models, providing customized services to ensure perfect matching with car air conditioning systems

The main functions of automotive air conditioning filters include:
Provide a good indoor air environment: It can filter impurities, small particles, pollen, bacteria, industrial waste gas, and dust in the air, ensuring the quality of the indoor air and protecting the health of passengers.
Protecting the air conditioning system: The air conditioning filter can prevent these impurities from entering the air conditioning system, reduce the wear and tear of the air conditioning system, and extend its service life.
Preventing glass fogging: By adsorbing moisture, it can prevent car glass from fogging, ensuring clear visibility for drivers and improving driving safety.
Therefore, the car air conditioning filter is crucial for maintaining the air quality inside the car and protecting the air conditioning system

The car air conditioning filter, also known as the air conditioning filter element, is mainly responsible for filtering the air entering the cabin, removing harmful substances such as dust, pollen, and bacteria from the air, ensuring the air quality inside the car, and protecting the air conditioning system. Its construction usually includes the following parts:
Housing: The housing of an air conditioning filter is usually made of plastic, which serves to protect the filter element and fix its position. The shell is designed with an air inlet and an air outlet to guide air flow.
Filter element: The filter element is the core part of the air conditioning filter, usually composed of multiple layers of materials. The outermost layer may be a pre filter layer used to capture large particles of dust and debris. The middle layer may contain activated carbon, which is used to adsorb odors and harmful gases in the air. The innermost layer is a fine filtering material, such as paper or non-woven fabric, used to filter smaller particles.
Sealing ring: A sealing ring is usually installed at the edge of the filter housing to ensure a good seal between the filter and the air intake of the air conditioning system, preventing unfiltered air from bypassing the filter and entering the cabin.
Installation buckle or slider: For ease of installation and replacement, air conditioning filter housings are usually equipped with installation buckles or sliders, allowing the filter to be easily secured in the air conditioning system.
Indicator (optional): Some advanced air conditioning filters may come with a replacement indicator, such as a color change or electronic signal, to alert the owner when the filter needs to be replaced
