HEPA Filters for Cleanroom & HVAC Air Filtration Systems

High-Efficiency Particulate Air Filtration for Critical Clean Air Applications

HEPA (High Efficiency Particulate Air) filters are high-performance air filters designed to remove airborne particles, microorganisms and fine contaminants from air streams where strict cleanliness control is required.

Classified according to EN 1822 and ISO 29463 standards, HEPA filters typically include H13 and H14 grades, providing extremely high filtration efficiency for submicron particles.

With advanced micro glass fiber media, optimized airflow channels and reliable sealing technology, HEPA air filters deliver stable particle removal performance while maintaining low pressure drop and long service life.

HEPA filters are widely used in:

Pharmaceutical manufacturing facilities 

Semiconductor cleanrooms 

Hospitals and healthcare environments 

Biological laboratories 

Aerospace manufacturing 

Precision industrial cleanrooms 

Food and beverage production

Why Are HEPA Filters Essential for Cleanroom Air Filtration?

In critical environments, even extremely small airborne particles can affect product quality, process reliability and human safety.

A properly designed cleanroom HVAC system typically uses:

Pre Filter → Medium Efficiency Filter → HEPA Filter → Terminal Air Supply

HEPA filters serve as the final filtration barrier to control airborne contamination before clean air enters critical areas.

They effectively remove:

Dust particles 

Aerosols 

Microorganisms 

Smoke particles 

Fine airborne contaminants 

Typical benefits include:

✔ Maintaining cleanroom cleanliness levels

✔ Protecting sensitive manufacturing processes

✔ Reducing airborne contamination risks

✔ Supporting GMP and ISO cleanroom requirements

✔ Improving process stability and product yield

Key Features & Benefits

High Filtration Efficiency for Submicron Particles

HEPA filters are designed to capture particles in the most penetrating particle size range (MPPS), typically around 0.1–0.3 μm.

Available grades include:

H13 HEPA Filter 

H14 HEPA Filter 

According to EN 1822 classification:

H13: ≥99.95% efficiency at MPPS 

H14: ≥99.995% efficiency at MPPS 

This high-efficiency performance makes HEPA filters suitable for applications requiring strict airborne particle control.

Advanced Micro Glass Fiber Filter Media

High-quality glass fiber media provides:

High particle capture efficiency 

Stable filtration performance 

Excellent temperature resistance 

Low particle shedding characteristics 

The optimized fiber structure enables efficient particle interception through:

Diffusion 

Interception 

Inertial impaction 

Electrostatic attraction

Low Pressure Drop & Energy-Efficient Design

HEPA filters are engineered to provide high filtration efficiency while maintaining optimized airflow resistance.
