Technical Education FAQs

Frequently asked questions regarding air filtration standards, compliance, and custom engineering training.

What is the difference between EN 1822 and ISO 29463 standards?
EN 1822 is the European standard for testing HEPA and ULPA filters based on MPPS (Most Penetrating Particle Size). ISO 29463 was created to harmonize filter testing globally and is derived from EN 1822, dividing filter classification into 13 distinct classes. Both verify 99.95% to 99.999995% efficiency levels.
How often should HEPA filters in ISO Class 5 cleanrooms be tested?
Under ISO 14644-2 guidelines, installed HEPA filter integrity (leak testing) in ISO Class 5 cleanrooms should be performed at maximum intervals of 12 months. High-risk pharmaceutical manufacturing facilities frequently perform leak testing every 6 months during scheduled maintenance shut-downs.
Does Filtravo UK provide custom technical training for maintenance teams?
Yes, Filtravo UK provides specialized engineering training modules for facility engineers, cleanroom operators, and quality auditors covering filter replacement safety, gel-seal inspection, and air velocity measurements. Contact us directly at info@filtravo.com for tailored training requests.
