This set includes one pre-filter, one medium-efficiency filter (H13 HEPA), and one high-efficiency activated carbon filter. Designed as a three-stage purification system, it filters harmful smoke and gases layer by layer, ensuring clean, breathable air for various industrial applications.
Primary Filtration (Pre-Filter Layer)
The first layer captures large particles such as dust, aerosols, and liquid droplets.
Reduces clogs and minimizes the burden on subsequent filters.
Secondary Filtration (H13 HEPA Filter)
The second layer efficiently captures particles larger than PM60 and retains fine particles like water vapor and liquid mists.
Provides a high level of purification while extending the lifespan of the high-efficiency filter.
Advanced Filtration (Activated Carbon Filter Layer)
Features high-iodine-value activated carbon that absorbs odors, toxic gases, and volatile organic compounds (VOCs).
Filters particles as small as 0.3μm with a precision rate of 99.997%, preventing secondary pollution and ensuring optimal air quality.
Pre-Filter: Absorbs water, liquids, aerosols, and oils, efficiently blocking large particles.
HEPA Filter: Captures fine particles and significantly reduces the load on the main filter.
Activated Carbon Filter: Neutralizes harmful gases and captures ultra-fine particles, ensuring clean air output.
Custom-designed for the KNOKOO FES220 Fume Extractor, providing a perfect fit and seamless operation.
Fully compatible as a replacement for old filters.

Each filter layer has a unique replacement cycle based on operating conditions:
Pre-Filter: Replace every 10–60 days, depending on dust accumulation.
HEPA Filter: Replace every 5–8 months to maintain high efficiency.
Activated Carbon Filter: Replace every 6–12 months to ensure peak performance.
Tip: Regularly replacing the pre-filter reduces maintenance costs and extends the lifespan of the HEPA and carbon filters.
Each filter layer can be replaced individually, making maintenance cost-effective.
Simple and intuitive replacement steps minimize system downtime.
Regular replacement of the pre-filter optimizes the performance of the entire system.
Regular Cleaning: Clean the filter compartment to avoid dust buildup and maintain proper airflow.
Use Original Filters: Ensure optimal performance and longevity by using genuine KNOKOO filters.
Timely Inspections: Check filters periodically for signs of wear or clogging to maintain system efficiency.
Industrial Use: Welding robots, soldering ovens, laser cutting, and laser engraving.
DIY Projects: Ideal for personal workshops, including welding and metal cutting.
Specialized Settings: Suitable for environments requiring high air quality, such as laboratories and cleanrooms.
