Custom Filter Manufacturing

-- Steady & Reliable Manufacturer --

Tailor your purification solutions with our Custom Filter Manufacturing services. As an OEM/ODM powerhouse, we recognize that every machine has unique airflow requirements and housing dimensions. We offer a "One-Stop" solution for brands looking to develop proprietary filtration stacks, from custom-sized HEPA filters to multi-stage composite filters combining carbon, zeolite, and antibacterial layers. Our engineering team works directly with you to optimize the "Pressure Drop vs. Efficiency" ratio, ensuring your products achieve the highest possible CADR ratings. Whether you need a small batch of filters for a niche medical device or high-volume production for a global air purifier brand, our flexible manufacturing lines are equipped to deliver precision-engineered filters that match your exact specifications.

Product Introduction

The Custom Manufacturing division is where your product vision comes to life. We utilize advanced CNC pleating machines and automated assembly lines that can be rapidly reconfigured for different shapes and sizes—including circular, oval, and multi-sided filters. We offer a vast library of filter media, including H11-H14 HEPA, high-iodine carbon, cold catalysts, and even aromatherapy-infused layers. Our "Composite Technology" allows us to bond these layers together into a single, easy-to-replace cartridge, simplifying the user experience for your customers. We also provide custom frame branding, including your logo and part numbers printed directly on the filter. Our R&D lab can perform CADR and CCM (Clean Cumulative Mass) testing on your custom prototypes, providing the data you need for certification and marketing. By partnering with us, you gain access to a world-class filtration laboratory and a manufacturing partner that scales with your business.
