In a laminar flow cabinet, air cleanliness directly affects experimental accuracy. READY Biotech provides primary filter replacement services, evaluating model compatibility and ensuring optimal performance after replacement.

? Difference Between Primary and HEPA Filters

A laminar flow cabinet typically includes two filtration stages:

• Primary Filter (Pre-filter): Installed at the air inlet to remove large particles and fibers, protecting the HEPA filter from clogging. Recommended replacement every 3–6 months depending on usage.

• HEPA Filter: Installed at the exhaust end, removing ≥0.3μm particles with 99.97% efficiency to maintain ISO Class 5 clean air. Typically replaced annually after professional airflow testing.

A clogged primary filter reduces airflow speed and increases pressure across the HEPA filter, risking contamination. Regular replacement maintains efficiency and prolongs HEPA filter life.

? READY Service Process
