1. What is an FFU? Why is it important in a cosmetics filling room under GMP?
Definition and structure of an FFU (Fan Filter Unit)
An FFU (Fan Filter Unit) is an air-filtration device that integrates a fan and a HEPA or ultra-fine particle filter, typically installed in the ceiling of a cleanroom. The FFU consists of three main components:
-
A fan: forces air flow through the filter.
-
A HEPA/ULPA filter: removes up to 99.99% – 99.9995% of fine particles and microorganisms.
-
A housing/frame: usually made of stainless steel or electro-painted steel, corrosion resistant.
This device operates independently and continuously, ensuring the maintenance of stable cleanliness levels in the space.
Role of the FFU in a cosmetics filling room
In the cosmetics-filling process — where the product comes into direct contact with the environment — any dust particles, microorganisms or contaminants can cause contamination and affect finished product quality. The FFU helps to:
-
Create a clean environment meeting ISO Class 5–8 depending on the area.
-
Prevent microbial contamination in the air.
-
Maintain positive pressure to keep dirty air from entering.
-
Protect the product and extend the service life of the filling equipment.
What does GMP require for air-control in a filling room?
Under Good Manufacturing Practices (GMP), environmental control is mandatory — especially in filling and sterile packaging areas. Key requirements include:
-
Air must be filtered through HEPA.
-
Pressure, temperature and humidity must be continuously controlled.
-
One-directional airflow or positive pressure must be present in the filling room.
-
Cleanroom class inversions (i.e., airflow reversals) must be avoided.
The FFU is an effective solution to meet these requirements without investing in a complex central AHU (Air Handling Unit) system.
Why is the FFU indispensable?
-
Easy to install — suitable for both new systems and retrofits.
-
More energy-efficient compared to a central system.
-
Provides stable cleanliness over time.
-
Supports businesses in obtaining GMP, ISO 22716 certification.
For cosmetics factories, especially during the filling stage — where high sterility and cleanliness are required — using an FFU is not just a choice but a standard requirement.

2. Criteria for selecting an FFU for a cosmetics filling room
To ensure the cosmetics filling room meets GMP standards, businesses need to choose cleanroom FFUs based on technical criteria suitable for required cleanliness, durability and stable operation in a continuous-production environment. Here are five important factors:
Filter efficiency (HEPA/ULPA) – Ensure Class 100–100,000 cleanliness.
- FFU must be equipped with HEPA (High Efficiency Particulate Air) or ULPA (Ultra Low Penetration Air).
- Minimum filtering efficiency:
-
HEPA H13: ≥ 99.99% for particles ≥0.3 µm.
-
HEPA H14: ≥ 99.995%.
-
ULPA: ≥ 99.9995% for particles ≥0.12 µm.
-
- Suitable for cleanliness levels from ISO Class 5 to Class 8 (equivalent to GMP Grade A–D).
Noise level, air-flow volume and static pressure
- Typical airflow: 800 – 1500 m³/h, depending on room area and air supply requirement.
- Higher static pressure helps ensure uniform airflow through the filter without performance drop.
- Noise level ≤ 50 dB: ensures a quiet working environment, avoids impacting operator comfort.
Construction materials – Durable and corrosion-resistant
- Common materials:
-
-
-
Stainless steel 304: corrosion-resistant, easy to clean, suitable for high humidity environments.
-
Electro-painted steel: cost-effective, good oxidation resistance.
-
-
- The surface must be smooth, dust-free, and chemically stable.
Size compatible with cleanroom ceiling system
- Standard sizes: 1175 × 575 mm or 1175 × 1175 mm.
- FFU must match the ceiling grid (module) of the cleanroom to prevent air leakage.
- Custom sizes available for specific plant design.
Energy saving and easy maintenance
- DC-fan design uses less energy compared to traditional AC fans.
- Modular design allows quick filter replacement without disrupting production.
- Ability to integrate a speed controller and remote pressure monitoring.

5. Guide to maintenance and correct filter replacement of FFU
To ensure the FFU system always operates stably and maintains GMP-standard cleanliness in the cosmetics filling room, businesses need to establish a scientific and strict maintenance and filter replacement process. Below are essential instructions:
-
Filter replacement cycle (HEPA/ULPA): 6 – 12 months depending on conditions
-
For typical cosmetics production environment: replace HEPA after 12 months of continuous operation.
-
For sterile filling areas or high contamination risk: shorten cycle to 6-9 months.
-
Do not reuse old filters because it reduces filtration efficiency and affects product quality.
-
-
Check airflow and differential pressure regularly
-
Install a differential pressure gauge to monitor pressure before and after the filter.
-
If the pressure difference exceeds allowable threshold (often > 250 Pa): check and replace filter immediately.
-
Abnormal airflow reduction is also a sign of filter blockage.
-
-
Clean the machine body and fan motor periodically
-
Remove protective grille and clean dust with a soft cloth; avoid strong chemicals.
-
Lubricate fan motor (if required) and check bearings, power cables.
-
Ensure the unit is always dry, no water accumulation or dust build-up inside.
-
-
Important note when replacing FFU filters
-
Use HEPA/ULPA filters that meet ISO standards — same model as the original for compatibility.
-
Install in the correct airflow direction; ensure perfect sealing between frame and filter (use rubber gasket or specialist sealant if needed).
-
After replacement, re-test efficiency and static pressure to ensure the device operates within specification.

6. FAQ – Frequently Asked Questions
Q: Is FFU necessary for all rooms in a cosmetics factory?
A: No. FFUs are only truly necessary for areas requiring high cleanliness, such as filling rooms, sterile packaging or raw-material weighing rooms. These are zones where the product directly contacts the environment and where microbial contamination risk is higher. For support areas (warehouse, corridor, office), a coarse filtration system or AHU may suffice.
Q: Can a HEPA filter be reused after cleaning?
A: No. HEPA filters are single-use. Their ultra-fine filter structure is highly sensitive and cannot be cleaned by standard methods without damage. Re-using an expired filter may lead to large reductions in filtering efficiency, failing to remove fine particles and microorganisms—posing risk to product quality.
Q: Does FFU generate a lot of noise?
A: Not if the right equipment is chosen. High-quality FFU models, especially those using modern DC fans, typically have noise levels under 50 dB — similar to a quiet office. This ensures a comfortable working environment for operators, particularly in long-duration production runs.
