Uncompromising Quality Control & International Standards
Operating under strict ISO, CE, and SGS certifications, we implement a 100% final performance testing protocol to ensure
every batch meets rigorous EN779 and ISO 16890 efficiency ratings.
Welcome to our Product & Quality FAQ section for air filtration products.
We use 100% premium synthetic polyester fibers with an incremental density structure. This multi-layer design ensures maximum dust-holding capacity and air purity in industrial environments.
Our Stereo-Glue (Full-Immersion Adhesive) process coats every fiber layer with resin. This creates a 3D adhesive matrix that captures micro-particles throughout the media’s entire depth.
Our F5 grade ceiling filters are engineered specifically for automotive spray booths and high-precision cleanrooms, providing a uniform, laminar airflow for a flawless paint finish.
Yes. We manufacture specialized Flame-Retardant Filter Media that is self-extinguishing and minimizes smoke emission, ensuring safety in high-heat industrial spray booths.
Our high-temperature fiberglass mats can withstand constant operating temperatures from 170°C to 250°C, making them ideal for paint-mist capture in baking ovens.
We utilize break-resistant thermal-bonded fibers and high-tack resin. This lint-free design prevents contamination, ensuring a zero-defect surface for sensitive painting projects.
Our media offers high DHC (e.g., 470G/㎡ for LH series). This extended capacity reduces replacement frequency, lowering the overall maintenance cost of your HVAC system.
Absolutely. Our Activated Carbon Media is optimized for the adsorption of volatile organic compounds (VOCs) and chemical odors, ensuring a safe and compliant working environment.
As a source factory with 20 years of expertise, we implement strict QC protocols—from raw fiber testing to final airflow resistance checks—ensuring every roll meets export standards.
For optimal efficiency, replace pre-filters weekly. Our premium Stereo-Glue ceiling filters offer a long service life of 500–600 hours, outperforming standard models.
Does your F7 pollen filter comply with European ISO 16890 and EN 779 standards? A: Yes. Our high-efficiency F7 filters are fully tested to meet EN 779 standards and match the ISO 16890 ePM2.5 classification. We utilize premium synthetic, moisture-resistant media blends to guarantee stable resistance and exceptional dust-holding capacity for European AHU and MVHR ventilation networks.
We construct our frames using double-wall, heavy-duty beverage board framed filter technology with high wet-strength properties. The filter media is laminated to a rust-resistant galvanized wire grid to maintain uniform V-pleat geometry, preventing frame twisting or buckling even at peak industrial face velocities.
We offer a versatile range of filtration media tailored to your specific application targets:
G2 to G4 Grades: Standard primary filtration utilizing progressive-density synthetic non-woven media, ideal for capturing coarse dust in general HVAC systems.
F7 to F9 Grades: Specialized high efficiency pleated panel filters with cardboard frame options for cleanrooms, capturing sub-micron particles (95~98% efficiency) to safeguard terminal HEPA filters.
Activated Carbon: Available upon request for combined particulate filtration and gas-phase odor removal.
As a vertically integrated manufacturer, Chuqi controls the entire supply chain from raw air filter media production to finished filter assembly. By engineering our own synthetic pocket filter media from scratch, we guarantee a high dust-holding capacity and ultra-low initial resistance while eliminating middleman markups to provide the most competitive factory-direct wholesale pricing. This seamless integration also allows our engineering team to instantly adapt production lines, delivering everything from standard pre-filters to specialized F9 high efficiency pleated panel filters with cardboard frame structures tailored to your exact technical specifications.
