Selection and Application of HEPA Filters

Technical Requirements for HEPA Filters

The filtration efficiency of HEPA filters (H13 grade) for 0.3μm particles is ≥99.97%, while ULPA filters can achieve a filtration efficiency of 99.9995% for particles ranging from 0.1 to 0.2μm.

Key Parameters for Selection

Filtration efficiency class (EN1822 standard)

Structural form (with partition/without partition)

Sealing method (liquid seal/magnetic seal)

Airflow specifications (pressure drop at rated airflow)

 Special Application Considerations

Bio-safety laboratories must consider sterilization methods

Electronic clean rooms require static electricity prevention measures

The pharmaceutical industry must comply with GMP requirements

The selection and application of air conditioning filters are crucial for ensuring the efficient operation of clean room air conditioning systems. By optimizing the combination of primary, medium, and HEPA filters, it is possible to meet the requirements of different cleanliness levels while achieving the lowest operational costs. With technological advancements, Suzhou Santy Clean Air Filter will continue to evolve toward smarter, more efficient, and more environmentally friendly solutions, providing more reliable air purification options for various industries.
