Air Filters
YANMAR GENUINE AIR FILTERS
Engine Protection Starts With Clean Air

Air quality directly affects engine performance, efficiency, and service life. Yanmar Genuine Air Filters are engineered to deliver consistent, high-efficiency filtration, ensuring that only clean, reliably filtered air enters the combustion chamber.
High-performance filter media captures dust and airborne contaminants down to 1 μm, preventing abrasive wear on critical engine components. By maintaining optimal airflow and filtration efficiency, Yanmar air filters support stable combustion, help avoid power loss, and help preserve fuel efficiency and emissions performance throughout the service interval.
The result is dependable engine operation, lower fuel consumption, and long-term protection. Exactly as designed by Yanmar.
Engineered Protection, Visible Inside
Because clean air is designed.
Inside every Yanmar Genuine Air Filter, engineered filtration protects engine performance where it matters most.Layered filter media captures harmful contaminants before they reach critical engine components, while maintaining stable airflow and consistent filtration efficiency.
Engineered design features include:
- Layered, high-density filter media for effective depth filtration
- Controlled airflow paths to ensure a consistent air supply
- High dust separation efficiency down to 1 μm
- Clean air is delivered to the engine with minimal restriction

Don’t settle for “non-genuine” air filters – demand the original. Find your authorised Yanmar dealer today.
Yanmar Genuine Air Filters ensure that only clean, consistently filtered air enters the engine. By removing dust and airborne contaminants before combustion, they protect critical components from abrasive wear and help maintain stable engine performance throughout the service interval.
Yanmar Air Filters are designed to achieve high dust separation efficiency down to 1 micron (μm). This level of filtration is essential for modern diesel engines, where even microscopic particles can accelerate wear and reduce long-term reliability.
Yes. Restricted or inconsistent airflow caused by poor-quality air filters can negatively affect combustion efficiency. This may lead to higher fuel consumption, power loss, and increased emissions. Properly engineered air filtration helps maintain optimal air-to-fuel ratios and efficient engine operation.
Depth filtration uses layered, high-density filter media to capture contaminants throughout the entire filter structure, not just on the surface. This allows Yanmar Genuine Air Filters to maintain airflow longer, reduce clogging, and deliver consistent filtration performance over time.
Non-genuine air filters may not meet the same material, design, or performance standards as Yanmar Genuine Air Filters. Inconsistent filtration efficiency or airflow can increase engine wear, reduce performance stability, shorten service life and increase the total cost of ownership.
