Frequently Asked Questions
Are you a trading company or a direct manufacturer?
We are a 20-year veteran source manufacturer owning the entire supply chain. Unlike trading companies, we manage everything from raw air filter media manufacturing to finished HVAC products in our own fully-owned factory, guaranteeing you premium quality and direct factory wholesale pricing.
What efficiency ratings and standards do your air filters meet?
Our products are fully compliant with internationally recognized standards, including ASHRAE 52.2 testing standards and ISO quality management systems. We supply MERV 8 & 13 pleated filters as well as MERV 11 to 15 (F6-F9) pocket and bag filters to meet strict global commercial bidding specs.
What is your standard lead time for bulk wholesale orders?
Thanks to our advanced, high-speed automated production lines, we maintain a reliable capacity and short lead times, even for peak-season bulk orders. Exact delivery times depend on your specific order volume and customization requirements, but we always prioritize on-time delivery to secure your project timeline.
Do you have experience with B2B exports and customs clearance?
Yes. We have over a decade of global shipping and B2B export expertise. We are fully experienced in handling international trade documentation and customs clearance, ensuring a smooth, hassle-free, and fully-insured delivery directly to your designated port or warehouse.
Can you manufacture custom sizes and provide private labels (OEM)?
Yes, absolutely. We offer 100% flexible OEM/ODM custom sizing support. No matter how complex or non-standard your specific commercial project requirements are, our engineering team can customize any odd dimensions and private brand labels to perfectly fit your brand.
How do your pleated and bag filters perform under high airflow conditions?
Engineered for demanding commercial HVAC systems, our pleated filters feature heavy-duty wire-backed synthetic media and moisture-resistant frames for zero-deformation. Our pocket filters use leak-proof galvanized steel headers and internal spacers to ensure uniform airflow and zero bag overlapping under heavy loads.
How do you pack the goods to prevent damage during ocean freight?
We utilize heavy-duty export packaging. All products are securely packed in reinforced, double-wall 5-ply corrugated cartons tightly loaded to prevent shifting. This rugged configuration withstands high pressure and ensures zero-damage maritime shipping without the need for unnecessary palletization space.
What is your Minimum Order Quantity (MOQ)?
As a factory-direct wholesale manufacturer, we generally operate on a bulk order basis to give you the maximum profit margins. However, we understand that new projects or custom OEM labels require flexibility, so we offer adaptable MOQs depending on the specific product category (media rolls, pleated, or bag filters). Please contact our team for a tailored quote.
