H13 HEPA Filter

About H13 HEPA Filter

The H13 HEPA Filter is a high-efficiency particulate air filter designed to remove at least 99.95% of airborne particles with a size of 0.3 microns. Certified according to the EN 1822 standard, H13 filters are used in environments requiring high levels of air cleanliness, such as hospitals, laboratories, cleanrooms, and advanced HVAC systems. Constructed with precision-pleated micro-glass fiber media and a rigid frame, the H13 filter ensures consistent performance, low pressure drop, and long service life.

• Frame Materials: Galvanized steel, aluminum, MDF, or ABS plastic

• Seal Options: Polyurethane gasket, neoprene gasket, or gel seal

• Construction: Mini pleat or deep pleat with separators

• Faceguard: Optional protective mesh on air-entry/exit sides

• Tested: Individually tested and certified for particle capture and integrity

• Applications: Cleanrooms, pharmaceutical production, medical facilities, food processing, biosafety cabinets, HVAC systems

Frequently Asked Questions (FAQs)

1. What is an H13 HEPA filter?

An H13 HEPA filter is a high-efficiency air filter that captures at least 99.95% of airborne particles measuring 0.3 microns, according to the EN 1822 standard. It sits between H12 and H14 in the HEPA classification hierarchy.

2. Whats the difference between H13 and H14 filters?

H13 filters capture 99.95% of 0.3-micron particles, while H14 filters capture 99.995%. H14 offers higher protection and is used in more sensitive applications like semiconductor manufacturing and Class 10 cleanrooms.

3. Where is an H13 filter used?

Common applications include:

• Hospital operating theaters

• Cleanrooms (ISO 7 and ISO 8)

• Biosafety cabinets

• Pharmaceutical processing

• High-end commercial HVAC systems

4. How long does an H13 HEPA filter last?

Typical service life ranges from 1 to 3 years, depending on the operating environment, airflow rate, and presence of pre-filtration. Monitoring pressure drop helps determine the right time for replacement.

5. Can H13 filters be washed and reused?

No, H13 HEPA filters are not washable. Washing can damage the fiber media and compromise filtration efficiency. Always replace with a certified unit.

6. How are H13 filters tested?

Each filter is individually tested using methods such as:

• EN 1822 (scanning particle efficiency test)

• DOP/PAO leak testing
  A label with performance data is typically affixed to every tested unit.

7. Do H13 filters remove viruses or bacteria?

Yes, due to their fine filtration capability, H13 filters can capture airborne bacteria, viruses, and other bioaerosols. They are commonly used in infection control applications.

8. Are custom sizes or materials available?

Yes. Manufacturers typically offer custom dimensions, frame materials, and sealing types to fit unique HVAC units or cleanroom systems.
