High Efficiency HEPA Filter

The high efficiency hepa filter uses a Mini-Pleat structure that forms the filtration media into dense, regular pleats. Hot-melt separators or other spacing methods are used to maintain consistent gaps between the pleats.

The main purpose of this design is to place a relatively large effective filtration area inside a comparatively thin filter structure. This is useful in clean-air systems where installation depth is limited but high-efficiency particle filtration is still required.

Available filtration grades include H13 and H14. The corresponding MPPS efficiencies listed in the source are ≥99.95% and ≥99.995%.

Filter-core thickness ranges from 53 to 130 mm. Rated airflow is 300–1,200 m³/h, and initial resistance is 50–150 Pa.

The Mini-Pleat structure focuses on the relationship between filtration area and available filter depth. By arranging narrow and regular pleats, more filter media can be installed without requiring the much greater depth associated with some traditional filter structures.

The supplied information also refers to existing Mini-Pleat HEPA/ULPA structures with filter-core depths of approximately 53 mm, 70 mm or 100 mm.

Increasing the media area within the available depth can help control filtration velocity and airflow resistance. The exact structure still needs to be matched to the required grade, rated airflow and installation space.

The high efficiency hepa filter can be used in semiconductor production, pharmaceutical facilities, biotechnology, electronics manufacturing, clean laboratories, clean benches and laminar-air supply systems.

For equipment where installation depth is restricted, the first purchasing step is to confirm available space together with the required airflow and filtration grade.

Jiangsu Renhe has teams working on air filtration materials, product development and manufacturing processes. Customized products can be configured according to equipment space, external frame dimensions, filtration grade, airflow and installation method.

OEM/ODM and manufacturing according to technical drawings are supported. The supplied information also states that the company has carried out core-material cooperation with external technical teams and universities.

For clean equipment projects, filter-core thickness, outside dimensions and sealing structure can be confirmed before mass production so the filter fits both the filtration requirement and available installation space.

Samples or prototypes can be discussed before full production, and the listed development period for a customized sample is 7 days.

Photos or videos can be supplied during manufacturing. Finished filters receive a 100% inspection before packing, and third-party inspection is supported.

Export orders can use cartons with three-plywood pallets or wooden cases to protect the relatively thin panel structure, pleated media and frame.

For cleanroom equipment and long-term replacement projects where filter depth is an important constraint, a high efficiency hepa filter with Mini-Pleat construction provides a way to combine H13/H14 filtration with a filter-core thickness range of 53–130 mm, while the final model is selected according to the actual airflow and resistance requirement.
