Choosing the right air filtration solution for your cleanroom is crucial, and understanding the distinctions between Fan Filter Units (FFUs) and HEPA Boxes is key.
Summaries
While both provide high-efficiency filtration, their differences dictate their ideal applications.
Similarities between FFU and HEPA Box
- Shared Applications: Both excel in pharmaceutical, healthcare, electronics, and chemical industries, ensuring air purity in cleanrooms of class 1,000, 10,000, and 100,000.
- Construction: Materials and thicknesses of their housings are often comparable, offering flexibility in customization.
- End-Stage Function: They serve as the final filtration stage in cleanroom purification projects, safeguarding compliance with air cleanliness standards.

Key Differences between FFU and HEPA Box
Structure:
- FFU: A self-contained unit, housing a HEPA/ULPA filter, a micro fan, and an enclosure.
- HEPA Box: A passive device comprising a static pressure box, a diffuser, and a HEPA filter, requiring connection to air ducts.
Application Scope:
- FFU: More versatile, suitable for cleanrooms of class 100 and above due to its built-in fan.
- HEPA Box: Primarily used in class 1,000 and higher cleanrooms, relying on an external air supply system.
Operation:
- FFU: An active filtration unit, generating its own airflow and operating independently or connected to ductwork.
- HEPA Box: A passive filtration unit, solely distributing pre-filtered air received through connected ducts.

In Short:
Understanding these distinctions empowers you to make informed decisions. Here's a quick guide:
- FFU: Ideal for flexible installations, demanding cleanrooms (class 100 and above), or limited space for centralized air handling systems.
- HEPA Box: Perfect for high-cleanliness environments (class 1,000 and above) with established centralized air conditioning systems.
Remember, selecting the optimal solution depends on your specific cleanroom requirements. Consider factors like cleanroom class, available space, budget, and operational complexity. Consulting an expert can ensure you choose the most effective and cost-efficient air filtration system for your needs.
