The function of a two-sided metal air filter cartridge is to provide effective filtration of air entering the engine, while also offering durability, reusability, and improved airflow characteristics compared to traditional paper filters.

Filtration: The primary function of the filter cartridge is to remove contaminants and particulate matter from the air before it enter the engine's intake system. This helps prevent dirt, dust, pollen, and other debris from entering the engine, which can cause damage and reduce performance over time.

Dual-Sided Filtration: The cartridge is designed with filtration material on both sides, effectively doubling the surface area available for trapping contaminants. This increases the filter's efficiency and capacity, allowing it to capture more particles and extend the interval between filter replacements.

Metal Construction: Unlike traditional paper or fabric air filters, metal air filter cartridges are constructed from durable metal materials such as aluminum or stainless steel. This construction provides several benefits, including resistance to corrosion, greater durability, and the ability to withstand higher temperatures and pressures.

Reusable and Washable: Many metal air filter cartridges are reusable and washable, allowing them to be cleaned and reused multiple times. This can provide cost savings over the long term compared to disposable paper filters, as well as reducing waste and environmental impact.

Improved Airflow: Metal filter cartridges typically have a more open and consistent structure compared to paper filters, allowing for improved airflow and engine performance. This can result in better throttle response, increased horsepower, and improved fuel efficiency.

Maintenance: Maintenance of a metal air filter cartridge involves periodic cleaning and inspection to ensure proper function. Depending on driving conditions and environmental factors, the filter may need to be cleaned more or less frequently than disposable filters. Regular maintenance helps ensure optimal engine performance and longevity.
