Frequently Asked Questions
The most common filter paper materials are cellulose (wood pulp), glass fiber, and blended media.
Cellulose paper is cost-effective for general air and oil filtration;
glass fiber delivers higher precision and temperature resistance for high-performance fuel and heavy-duty oil applications;
blended media balances efficiency, strength and cost for mainstream automotive filters.
The required filtration rating depends on your application and component protection needs.
Engine oil filters typically use 10–25μm media, fuel filters use 2–10μm for fine particle and injector protection, and engine air filters use 10–40μm media. Our technical team can recommend the optimal grade based on your performance requirements.
We provide standard roll widths and full custom slitting services. Widths can be customized from 10mm to 1600mm with a tolerance of ±0.5mm. Standard core inner diameters are 76mm and 152mm, with custom core sizes available upon request.
Yes, we provide A4-sized sample sheets or small roll samples of standard grades free of charge, with the buyer covering shipping costs. Custom development samples require a sampling fee, which will be credited against your first bulk order.
For standard stock grades, the MOQ is 3000kg per specification. For custom slitting of standard grades, the MOQ is 5000kg per width. For custom formulation or special treatment grades, the MOQ starts at 5000kg depending on technical requirements.
Standard stock grades have a lead time of 7–15 days. Custom slitting orders take 15–20 days, and custom formulation development orders take 25–40 days depending on technical complexity.
