Synthetic Fiber Pocket Filter F6 is a medium-high efficiency air filtration device that complies with EN 779:2012 and ISO 16890 standards. It is designed to intercept 0.5-5μm fine particles (such as bacteria, smoke, pollen and some aerosols). It adopts a high-density polyester fiber composite structure and an optimized bag layout. While maintaining low airflow resistance, it achieves F6-level filtration efficiency (corresponding to MERV 12-13). It is suitable for scenes with high cleanliness requirements such as medical, electronic manufacturing, and food processing. It is a key component to ensure air quality and equipment protection.
Core structure and technical parameters
Material and process
Filter material: electrostatically charged polyester fiber (PET) non-woven fabric, fiber diameter ≤2μm, progressive filtration is achieved through gradient density design (outer layer coarse efficiency + inner layer high efficiency), and surface anti-static treatment reduces secondary particle flying.
Bag structure: 8-16 V-shaped pleated filter bags, the effective filtration area is 4-7 times that of flat filter media, and the dust holding capacity is 600-1000g/m².
Sealing frame: galvanized steel or reinforced ABS plastic frame, temperature resistance range -30℃ to 70℃, the edge is sealed with polyurethane strips to ensure no side leakage.
Performance parameters
Filtration efficiency:
PM1.0 filtration efficiency ≥ 60% (ISO ePM1 60%+), PM2.5 ≥ 85% (ISO ePM2.5 85%+);
The interception rate of 0.5μm particles is ≥ 80% (EN 779 F6 standard).
Initial pressure difference: ≤70Pa (@ rated air volume), the operating energy consumption is 20% lower than that of traditional filter elements.
Humidity tolerance: ≤85% RH (optional hydrophobic coating, moisture-proof and mildew-resistant).

Typical application scenarios
Medical health:
Hospital operating room, ICU ward fresh air system, intercept bacteria and virus carriers, reduce infection risk;
Biological laboratory ventilation, protect precision instruments from particulate contamination.
Electronic manufacturing:
Semiconductor dust-free workshops, LCD production lines, control particles above 0.5μm, maintain ISO Class 7 cleanliness;
Data center air conditioning systems, prevent dust deposition from causing equipment overheating.
Food and pharmaceuticals:
Aseptic filling workshops, pharmaceutical factory HVAC systems, intercept microorganisms and dust, meet GMP certification requirements;
Dairy processing lines, prevent odor and foreign matter from mixing.
Business and transportation:
Airport terminals, high-speed rail station central air conditioning, improve indoor air quality (IAQ);
Museums, archives, protect cultural relics from dust erosion.
Selection and maintenance guide
Accurate selection
Air volume matching: select the number and depth of filter bags according to the system air volume (such as 5000m³/h corresponds to 12-16 bags, depth ≥300mm);
Pollution characteristics:
High microbial risk (such as hospitals): select antibacterial coating filter material (silver ion/copper ion impregnation);
High humidity environment (such as food factories): select hydrophobic treatment frame and filter bag.
Smart maintenance
Pressure difference monitoring: The recommended replacement threshold is the initial pressure difference × 2.5 (usually ≤175Pa) to avoid efficiency loss;
Cleaning suggestions: Surface dust can be cleaned with a vacuum cleaner, and water washing or high-pressure backwashing is prohibited (irreversible damage to the electrostatic layer);
Replacement cycle:
Low-load scenario (commercial building): 12-18 months;
High-load scenario (electronic workshop): 6-9 months.
Technological innovation and industry trends
Smart sensing: integrated pressure difference sensor and RFID chip, real-time upload of filter element life to the building management system (BMS);
Multifunctional composite: optional activated carbon interlayer (Hybrid model), simultaneous adsorption of formaldehyde, ozone and odor;
Sustainable upgrade: using recycled polyester fiber (rPET), carbon footprint reduced by 25%, in line with the EU Green Deal.
