Cleanroom design continues to evolve with advances in technology and changing industry requirements. Here are the key best practices for 2026: Energy Efficiency Modern cleanrooms must balance cleanliness requirements with energy consumption. Key strategies include: Variable Air Volume (VAV) systems that adjust airflow based on occupancy and activity EC motor technology in FFU units for 30-50% energy savings Heat recovery systems to capture and reuse energy from exhaust air LED lighting with occupancy sensors Automation and Monitoring Building Management Systems (BMS) now provide real-time monitoring of: Particle counts and air quality Temperature and humidity control Pressure differentials between zones Filter status and replacement alerts Modular Design Modular cleanroom systems offer flexibility and faster installation: Pre-fabricated wall panels an...

HEPA (High-Efficiency Particulate Air) filters are classified according to their filtration efficiency, which is determined by international standards such as EN 1822 and ISO 29463. Understanding these classifications is crucial for selecting the right filter for your specific application. HEPA Filter Classification System HEPA filters are categorized into different classes based on their efficiency at capturing particles of 0.3 microns in size: H10: 85% efficiency at MPPS (Most Penetrating Particle Size) H11: 95% efficiency at MPPS H12: 99.5% efficiency at MPPS H13: 99.95% efficiency at MPPS H14: 99.995% efficiency at MPPS What is MPPS? MPPS stands for Most Penetrating Particle Size, typically around 0.3 microns. This is the particle size that is most difficult to capture, making it the standard...
