Besin’s Ultra-Micro Electrostatic Filter: A Breakthrough Solution for GMP Cleanroom Air Purification

Taizhou, China – April 2025 – Besin Environmental Protection Technology (Taizhou) Co., Ltd., a pioneer in bio-pharmaceutical cleanroom air purification, has introduced its revolutionary ultra-micro electrostatic filter technology, offering a superior alternative to traditional medium-efficiency filters in pharmaceutical cleanroom applications.

Meeting Stricter Industry Standards with Advanced Filtration

With the rigorous enforcement of GMP (Good Manufacturing Practice) and ISO 14644 standards, pharmaceutical cleanrooms demand higher air cleanliness than ever before. Conventional medium-efficiency filters, however, suffer from high consumable costs, inefficient dust retention, safety concerns, and labor-intensive maintenance—posing significant challeng
es for the industry.

A Game-Changing Solution: Ultra-Micro Electrostatic Air Filter

Besin’s proprietary ultra-micro electrostatic air filter employs an interlaced electrode membrane design, generating a high-intensity electric field that ensures efficient air purification and instant microbial disinfection, surpassing the limitations of traditional filtration methods.

Key Advantages:

✔ Superior Dust Retention – 325 mg/(m³/h) dust-holding capacity (9× higher than national standards), extending maintenance intervals to 1 year.
✔ Washable & Reusable – Withstands 100+ wash cycles without performance loss, eliminating filter replacements and drastically reducing 10-year operational costs.
✔ High-Efficiency Filtration + Sterilization – ≥98% single-pass efficiency for particles ≥0.5μm, coupled with a >99% sterilization rate.
✔ Ultra-Low Resistance – <10 Pa resistance (at 1 m/s airflow), reducing HVAC energy consumption.
✔ Safe & Sustainable – Zero ozone emissions, compliant with multiple safety and environmental certifications.

Proven Benefits for Pharmaceutical Manufacturers

Extensive lab testing by Besin confirms that the ultra-micro electrostatic technology delivers tangible cost and efficiency benefits:

• Faster ROI – Savings on consumables and energy lead to quick cost recovery.

• Lower 10-Year TCO –Significant reductions in filter replacement, energy, and maintenance expenses.

• Eco-Friendly Operation – The low-resistance design minimizes fan power usage, supporting green manufacturing initiatives.

Certified & Ready for High-Sensitivity Applications

The technology has passed multiple national certifications and complies with GMP cleanroom requirements, making it ideal for:

• API (Active Pharmaceutical Ingredient) purification

• Aseptic filling processes

• High-humidity environments (RH >90%)

• Agri-pharmaceutical crossover applications
