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
