Cleanroom HEPA Filter

HEPA (high-efficiency particulate air) filters are designed to meet specific efficiency standards, removing at least 99.95% (ISO, European Standard) or 99.97% (ASME, U.S. DOE) of particles with a diameter of 0.3 μm. They capture a wide range of particles, including pollen, dust, bacteria, and some viruses. HEPA filters were commercialized in the 1950s and are used in various applications requiring contamination control, such as in hospitals, manufacturing, and homes.

Standard HEPA Filters: Standard usually used is the European Union Norm EN 1822:2009

Key Features

Mechanism: HEPA filtration works by mechanical means unlike the Ionic and Ozone filtration.

Safety:  Use negative ions and ozone gas respectively So, the chances of potential pulmonary side-effects like asthma and allergies is a much lower with HEPA purifiers.

High Efficiency: HEPA filters capture at least 99.97% of airborne particles as small as 0.3 micrometers, ensuring a high level of air purity.

Particle Removal: They effectively remove a wide range of contaminants, including dust, allergens, bacteria, and viruses, which is crucial for maintaining cleanroom standards.

Airflow Control: HEPA filters help maintain laminar airflow, which is essential for preventing the recirculation of contaminants and ensuring a controlled environment.

Regulatory Compliance: Use of HEPA filters is often required to meet stringent regulatory standards and guidelines, such as those set by the FDA and ISO.

Enhanced Equipment Performance: By reducing the presence of harmful particles, HEPA filters help protect sensitive equipment, extending its lifespan and improving overall productivity.
