Frequently Asked Questions
-
HEPA air filters are commonly replaced every six to twelve months, depending on airflow, system usage and contamination levels. Facilities with high particle loads or critical air-quality requirements may require more frequent replacement.
-
No. HEPA filters should not be washed or vacuumed because this can damage the filter media and reduce filtration efficiency. Damaged filters should be replaced with appropriate HEPA replacement filters.
-
Standard HEPA filters are designed to capture airborne particles rather than gases or odours. For smoke, chemical vapours and odours, HEPA filters are often combined with activated carbon or specialised filtration media.
-
Signs that a HEPA filter may require replacement include reduced airflow, increased system pressure or reaching the recommended replacement period. Regular inspections and pressure monitoring can help determine when replacement is necessary.
-
HEPA filtration systems must meet applicable requirements covering airflow, filtration efficiency and particle removal. Rainbow Air Systems supplies HEPA filters designed to meet relevant compliance and quality requirements.
Since 1956, Rainbow Filters has offered much more than air filters. In fact, we propose the highest quality air filtration solutions with huge advantages in terms of both effectiveness and economy.
