ISO 5 Compliant Air Filter: The Definitive Guide to Particle Control and Standard Adherence
Achieving and maintaining an ISO 5 environment (formerly known as Class 100) is a complex engineering feat. The ISO 5 compliant air filter serves as the primary barrier against microscopic contamination, ensuring that sensitive processes in semiconductor fabs and pharmaceutical filling lines remain uncompromised.
Understanding ISO 5 Standards (ISO 14644-1)
According to ISO 14644-1, an ISO Class 5 cleanroom must limit the concentration of particles to the following thresholds:
≥0.1μm: Max 100,000 particles/m³
≥0.5μm: Max 3,520 particles/m³
≥5.0μm: Removed from the classification table (equivalent to GMP Grade B at rest).
HEPA vs. ULPA: Which Filter is Right for ISO 5?
While ISO 5 can be achieved with high-quality HEPA filters, many Tier-1 facilities are shifting toward ULPA for an extra margin of safety:
HEPA H14: Efficiency of 99.995% at 0.3μm. Ideal for most pharmaceutical and medical applications.
ULPA U15: Efficiency of 99.9995% at 0.12μm. Recommended for advanced semiconductor lithography and nanotechnology.
Why Deshengxin is the Expert in ISO 5 Filtration Solutions
As a vertically integrated manufacturer, Deshengxin (DSX) optimizes the entire purification system, not just the filter media:
Airflow Stability: Our FFU and EFU units are powered by in-house motors, ensuring a constant laminar flow velocity of 0.45m/s±5%—the benchmark for ISO 5 uniformity.
Zero-Leakage Sealing: We specialize in Gel Seal (Liquid Seal) technology, which provides a failsafe airtight interface for(https://www.ffufan.com/hepa-filter.html) , preventing bypass air from contaminated plenums.
100% Factory Validation: Every unit undergoes automated PAO/DOP scan testing in our Class 100 workshop to ensure compliance with EN 1822 and ISO 29463 standards.
Application Matrix: ISO 5 vs. GMP Grades
Environment | Particle Limit (≥0.5μm) | Recommended DSX Filter | DSX Recommended ACH |
ISO 5 (Class 100) | 3,520/m³ | HEPA H14 / ULPA U15 | 240 – 480 |
GMP Grade A | 3,520/m³ (In Operation) | Gel Seal HEPA H14 | Unidirectional Flow |
GMP Grade B | 3,520/m³ (At Rest) | Mini-Pleat HEPA H14 | 40 – 60 (Minimum) |
