The Thesvin American Range Hood Filter is a composite oil-mist and odor filter designed for American-style range hoods and ductless recirculating kitchen ventilation systems. It combines a multi-layer corrugated aluminum foil maze with flame-retardant polyester fiber and an activated carbon layer to capture heavy grease and adsorb cooking odors. This filter is intended for range hood manufacturers, commercial kitchen equipment suppliers, and OEM/ODM buyers who need a UL 900–compliant, custom-sized filter that fits directly into their hood's existing slot or frame.
Fitment starts with the frame. The Thesvin filter uses a high-strength aluminum frame that can be configured with different handle styles and plastic or metal clips to match the mounting slot of your hood. Because the frame is the primary locating feature, we customize its length, width, thickness, and clip position to your drawing or original part, so the filter seats firmly without adapters.
The sealing interface is equally important. The aluminum frame is designed to sit flush against the hood's filter slot, and the handle and clip options are chosen to match your installation method—whether the filter slides in from the front or drops into a top-access opening. This attention to the interface helps maintain a consistent fit across production batches and reduces callbacks related to rattling or misalignment.
For ductless recirculating hoods, the filter also acts as the primary odor-control element. The activated carbon layer is integrated behind the aluminum foil maze, so the overall thickness is controlled by the frame and foil stack. We confirm the thickness and foil layer count during sampling to ensure the filter does not interfere with the hood's blower or airflow path.
The filter targets two main contaminants in kitchen exhaust: grease particles and cooking odors. The multi-layer corrugated aluminum foil creates a three-dimensional labyrinth that traps heavy oil mist before it reaches the motor and fan wheel. The flame-retardant polyester fiber adds a secondary capture layer, while the high-iodine-value activated carbon layer adsorbs volatile odor compounds from cooking fumes.
This three-in-one composite structure is suited to both recirculating and ducted hoods where odor control is required. In recirculating mode, air passes through the filter and returns to the kitchen, so the carbon layer helps reduce lingering smells. In ducted mode, the filter protects the blower and downstream ductwork from grease buildup. The aluminum foil and frame are washable, but the carbon layer is not intended for repeated washing; replacement intervals depend on cooking load and should be confirmed with Thesvin during specification.
The filter is tested to UL 900 Class 1 / Class 2 flame-retardant safety standards, which addresses fire safety in kitchen exhaust applications. This makes it suitable for residential range hoods as well as commercial kitchen exhaust systems that require documented flame spread performance.

Thesvin operates a 50,000 m² production facility with 6 clean workshops totaling 20,000 m², supported by multiple automated production lines and a monthly capacity of millions of pieces. Quality control follows IQC, IPQC, and OQC at every stage: incoming aluminum foil and activated carbon are inspected, in-process dimensions and foil stacking are checked, and finished filters are inspected for frame flatness, clip fit, and appearance before packing.
The company holds IATF 16949 (obtained in 2024), ISO 9001, ISO 14001, and ISO 45001 certifications. Its in-house CNAS-accredited laboratory can issue test reports for filtration efficiency, dust holding capacity, and pressure drop. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. With over 20 years of filtration manufacturing experience and more than 20 years of continuous exports to Europe, the United States, Japan, and South Korea, Thesvin supports OEM/ODM customization of size, structure, filter media grade, frame material, logo, and packaging, and has developed more than 1,000 filtration solutions.
To receive a quotation and fitment confirmation, please send us your device or hood model, a size drawing or the old filter, the required airflow or water flow (if applicable), operating conditions (temperature, grease load, recirculating or ducted), and your estimated quantity. Our engineering team will review the interface and respond with a custom specification and sample plan. Contact Thesvin to start your inquiry.
Fitment depends on matching the frame length, width, thickness, and clip position to your hood's filter slot. Thesvin customizes the aluminum frame and clip style to your drawing or original part, so the filter seats correctly. Send us your hood model or a sample for confirmation.
Yes. An old filter is often the most reliable reference for frame dimensions, handle position, and clip type. We will measure it and confirm the specification with you before producing a sample.
The aluminum foil maze physically intercepts heavy grease, while the activated carbon layer adsorbs cooking odors. Efficiency depends on foil layer count, carbon grade, and airflow; Thesvin can provide test data from its CNAS-accredited laboratory for the agreed specification. Please share your airflow and grease load so we can recommend the right configuration.
The filter complies with UL 900 Class 1 / Class 2 flame-retardant safety test certification standards. This addresses fire safety for kitchen exhaust applications. We can supply documentation for your compliance review.
Yes. We offer 100% tooling to your equipment dimensions, including length, width, thickness, and foil layer count. Frame handles and plastic or metal clips can be selected to match your mounting slot, and logo and packaging can be customized.
Standard specifications typically have an MOQ of 1,000–2,000 pieces; custom specifications are quoted separately. Lead time is normally 25–35 days for standard orders and 35–50 days for custom tooling, depending on mold development.
Replacement interval depends on cooking load and whether the hood is recirculating or ducted. The aluminum foil and frame can be washed, but the activated carbon layer loses adsorption capacity over time and should be replaced. We recommend confirming a replacement schedule with Thesvin based on your usage.
Yes. We welcome sample requests. Standard specification samples can be provided free of charge with the customer covering international courier costs; custom samples may incur a tooling fee, which is typically refundable against a bulk order. Contact us with your requirements to arrange a sample.
