H13–U16 PTFE Mini-Pleat HEPA/ULPA Filter for Cleanrooms

Features

Low-resistance PTFE membrane filtration in 30 mm and 50 mm panel depths for cleanroom terminals, FFUs and controlled industrial air systems. Standard grades include H13, H14, U15 and U16. The HF-PTFE filter uses PTFE membrane media in a compact pleated panel. It is designed for projects that require high particulate filtration efficiency with controlled initial resistance. Standard aluminum-alloy panels are available in three face sizes and two depths, with rated airflow from 470 to 2100 m³/h.

H13 to U16 Grade Options:Select the required grade against the project test standard and cleanliness target.
Low Initial Resistance:Published initial resistance ranges from 65 to 115 Pa, depending on panel depth and efficiency grade, at the stated rated airflow.
Compact Panel Depth:Standard 30 mm and 50 mm options support installations where filter depth is limited.
Project-Specific Configuration:Dimensions, airflow, seal, labeling and packaging can be reviewed for OEM and cleanroom projects.

Why Use PTFE Membrane Media?

PTFE membrane media can provide high particle-capture efficiency at a lower resistance than a conventional glass-fiber configuration designed for the same duty. The actual difference must be compared at the same filter size, grade, airflow and test method.

The membrane construction is also selected where resistance to moisture or specific process chemicals is important. Compatibility is not universal. Provide the chemical name, concentration, temperature, humidity and exposure pattern before specifying the filter for a corrosive or decontamination environment.

Compact Mini-Pleat Construction

The pleated pack increases the effective media area within a 30 mm or 50 mm panel. A deeper 50 mm filter provides lower published initial resistance than the corresponding 30 mm model at the same face size, airflow and efficiency grade.

The final configuration includes the PTFE media pack, aluminum-alloy frame and selected sealing components. Gasket, gel or other sealing arrangements must match the terminal housing and installation method.

Efficiency and Testing

The current product range lists H13, H14, U15 and U16. Before ordering, confirm:

the applicable EN 1822 or ISO 29463 edition;
the required overall and local efficiency at MPPS;
the rated airflow used for the test;
the challenge aerosol and scan method;
the leakage acceptance limit;
whether the buyer needs an individual report, label values or lot-level certificate.

The existing page states that filters are individually tested and that airflow, resistance, efficiency and leakage are inspected before shipment. The exact test procedure and document format must be confirmed in the quotation.

Applications

Cleanroom Terminal Filtration:Final-stage filtration for controlled supply-air systems.
Fan Filter Units:Thin panel options for FFU configurations that match the listed dimensions and airflow.
Semiconductor and Electronics Production:Particle control in clean manufacturing areas, subject to process-specific contamination and material requirements.
Pharmaceutical and Biotech Facilities:Clean-air filtration where the selected grade, sealing and test documentation meet the project specification.
Laboratories:Supply-air or equipment filtration for controlled environments.
Industrial HVAC Terminals:Final filtration where high efficiency and low initial resistance are required.

Hospital, food-processing and other regulated applications require project-specific review. A filtration grade alone does not establish regulatory compliance.

Customization and Quality Control

Dimensions and Airflow

Custom sizes and airflow ratings can be reviewed against the terminal or FFU drawing. Pressure drop must be confirmed at the requested rated airflow.

Efficiency Grade

H13, H14, U15 and U16 are listed as available. Do not select a grade by efficiency percentage alone; specify the standard, test method and local leakage requirement.

Sealing

The page lists custom gasket and sealing options. Provide the housing drawing, sealing direction and contact surface so the filter-to-housing interface can be checked.

Inspection

The current quality-control scope includes material inspection, pleating and assembly control, airflow, resistance, efficiency, leakage and appearance inspection. Confirm which results appear on the label, inspection certificate or individual report.

FAQ

What efficiency grades are available?

The current range lists H13, H14, U15 and U16. Confirm the required EN 1822 or ISO 29463 classification and MPPS acceptance criteria before ordering.

Is the PTFE HEPA filter washable?

The current technical content does not provide an approved washing procedure or post-wash performance data. The filter should not be marketed or maintained as washable unless Healthy Filters supplies a validated cleaning method.

Is this a high-temperature HEPA filter?

No maximum operating temperature is stated on the page. Do not select it for a high-temperature process until the PTFE media, adhesive, frame and sealing components have been reviewed against the required temperature.

Why does the 50 mm filter have a lower initial resistance?

The published table shows lower initial resistance for the 50 mm version than the 30 mm version at the same face size, airflow and grade. The deeper pack provides more room for filter media within the panel.

Is every filter individually tested?

The current page states that individual performance testing is performed before shipment. Confirm the test method, leakage limit and report format in the quotation, especially for cleanroom validation projects.

What information is required for a quotation?

Provide W × H × D, efficiency grade, test standard, rated airflow, maximum initial resistance, housing/seal type, operating temperature and humidity, quantity, label requirements and required test documents.
