Quality & Performance：

Material & Workmanship

Housing is heavy-duty galvanized steel with anti-rust treatment - won't rust or bend out of shape easy.

Filter element is a double-layer combo of high-density paper and melt-blown fabric - filters clean and holds tons of dust before you have to swap it out.

We make these with precise pleating, ultrasonic edge sealing and strict airtightness checks.

Our automated lines pump out 80,000 units a year, so big bulk orders are no sweat.

Quality Checks

Three quality picks to choose from:

Genuine: Exact original parts, meets SINOTRUK's official specs

OEM Grade: Built to original standards, solid bang for your buck

High-quality Aftermarket: Reliable replacements for day-to-day use

Our factory has ISO9001 certification. Every filter gets checked for filtration precision, seal tightness, pressure resistance and temperature tolerance.

Each unit has a unique serial number, so we can trace batches if needed.

Service Life (Normal Use)

Quality Grade	Service Life
Genuine	≥ 80,000 km / 1.5 years
OEM Grade	≥ 60,000 km / 1 year
High-quality Aftermarket	≥ 40,000 km / 6 months

Double-layer filter holds 30% more dust than regular single-layer ones.

The heat-resistant material works great whether it's scorching hot or freezing cold. In dusty spots, it fails 30% less often than standard air filters.
