Custom Slender HEPA Filter with Kraft Paper Frame Custom Size Filtration Grade

1. Kraft Paper Frame HEPA Filter: Customized for Narrow Spaces

This HEPA filter features a kraft paper frame structure, allowing for precise customization of its length, width, and thickness to fit the narrow internal space and installation slots of your equipment. The kraft paper frame combines lightweight design with structural stability, perfectly embedding into devices such as long, narrow air purifiers and duct filter modules, making it suitable for space-constrained purification scenarios.

2. Comprehensive Customization Solutions to Match Specific Equipment Filtration Needs

We support multi-dimensional customization for this filter: in addition to size and frame material, you can choose H10-H14 HEPA filtration levels as needed. We also support adjustments to filter thickness and pleat density (balancing filtration efficiency and ventilation resistance). Whether for commercial duct filtration, small industrial equipment purification, or long, narrow household air purifiers, customization ensures both performance and installation suitability.

3. High-Density Pleated Filter Media: Balancing High-Efficiency Purification and Durability

The filter uses high-density pleated filter media technology, maximizing the filtration contact area within a narrow space. It achieves a filtration efficiency of over 99.97% for 0.3-micron particles, effectively intercepting dust, smoke, and fine impurities. The sealing process between the filter media and the kraft paper frame is reinforced to prevent airflow bypass and ensure stable purification performance.

4. Flexible Supply System to Adapt to Equipment Manufacturers' Bulk Needs

We offer flexible customized supply services: supporting small-batch sampling (for equipment model testing) and large-scale stable supply, with delivery cycles adjusted according to the equipment manufacturer's production schedule. Each batch of filters undergoes filtration efficiency, dimensional accuracy, and frame strength testing to ensure that delivered products perfectly match customer needs, helping equipment manufacturers quickly implement purification solutions.
