How Often Should HEPA Filters Be Replaced?

HEPA filters are critical components in laminar flow cabinets and BSCs. Replacement frequency depends on usage and environment.

Typical replacement intervals:

■ General laboratory use: every 1–2 years
■ High usage or contamination: every 6–12 months
■ Cleanroom environments: based on testing results

Signs That Replacement Is Needed

■ Weak or unstable airflow
■ Failed cleanliness tests
■ High particle counts
■ Pressure drop issues
■ Exceeded recommended usage time

Recommended Testing

■ HEPA filter integrity test
■ Airflow velocity test
■ Particle count test

■ Microbial testing
