European Range Hood Filter with Activated Carbon for Recirculating Cooker Hoods

This is a European-style range hood filter made by Oltaven that combines an aluminium foil micro-perforated mesh, flame-retardant polyester fibre and an activated carbon layer in one finished part. It captures heavy grease and adsorbs cooking odours for recirculating (ductless) cooker hoods, open-plan kitchens and commercial kitchen exhaust cleaning systems. It is built for appliance brands, OEM/ODM buyers and wholesalers who need a finished filter, not just raw media.

From Media to Finished Filter

A filter is often described by its media, but the media alone does not decide what the user experiences. The same aluminium foil mesh can end up as a low-resistance grease screen or a dense odour filter depending on how it is pleated, framed and sealed. Oltaven sells the finished filter, so the forming steps are part of the product.

In this range hood filter, the aluminium foil micro-perforated mesh handles the first job: separating and capturing heavy oil and grease. The flame-retardant polyester fibre supports the structure and helps hold the activated carbon layer in place. The activated carbon, in granular or powder form, adsorbs cooking odours such as oily smoke smells and spicy notes. Each layer has a role, and the order in which they are combined affects both grease capture and odour control.

Framing is the next decision. The outer frame can be high-strength aluminium alloy profile or a stainless steel frame, and optional clips and handles can be added. The frame keeps the layered media flat, holds the part rigid during handling and cleaning, and defines how the filter sits in the hood. Sealing and edge finishing then close the media stack so air passes through the filter rather than around it.

What Decides Finished Performance

Three outcomes matter to a cooker hood designer: efficiency, resistance and capacity. Efficiency is how much grease and odour the filter removes. Resistance is the pressure drop the fan must overcome. Capacity is how much contaminant the filter holds before performance drops. Media choice sets the starting point, but pleating, framing and sealing decide the finished result.

Pleating and layer build change the effective surface area and the path the air takes. A denser carbon layer can improve odour adsorption while adding resistance. A more open aluminium mesh can lower resistance while shifting the balance toward grease capture. The frame and edge seal prevent bypass, so the air that is counted actually passes through the media. For a recirculating hood, this balance is what the user hears as fan noise and smells as cooking odour returning to the kitchen.

Because Oltaven controls the forming steps, the specification can be tuned to the appliance. Buyers can discuss layer build, mesh openness, carbon loading and frame type together, instead of choosing a media roll and hoping the finished part behaves the same way.

Applications

This filter is designed for recirculating cooker hoods, where air is cleaned and returned to the kitchen rather than ducted outside. That makes odour adsorption as important as grease capture. It suits open-plan kitchens where cooking smells would otherwise spread into living areas, and it fits European-style top-draft and side-draft hoods.

Commercial kitchen exhaust cleaning systems can also use the same finished filter concept, where grease and odour control are needed in one replaceable part. Appliance brands may specify the filter as a service part or as original equipment. The construction is also relevant to buyers who need a flame-retardant filter: the product complies with UL 900 Class 1 / Class 2 fire safety test certification.

Technical Specifications

The Oltaven Factory and Certifications

Oltaven works with appliance brands as an OEM/ODM partner and has developed more than 1,000 filtration solutions over 20+ years of research and manufacturing experience. That experience is applied to finished filters, including the forming, framing and sealing steps described above.

The production base covers a 50,000 m² plant, including six cleanrooms with a combined area of 20,000 m². A self-built laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust holding capacity and resistance. The company has held ISO 9001, ISO 14001 and ISO 45001 system certifications, and obtained IATF 16949 automotive quality management system certification in 2024.

Products meet REACH and RoHS environmental requirements, and compliance documents can be provided. Quality control runs through IQC, IPQC and OQC. The address is Zhongshan, Guangdong, China.

OEM/ODM Workflow

1. Share the device or vehicle model, a size drawing or sample, and the airflow or water flow requirement.
2. Confirm operating conditions, target efficiency and the frame, handle or clip options.
3. Review the proposed layer build and forming approach with the engineering team.
4. Produce samples for fit and performance checks.
5. Approve the sample, packaging and logo requirements.
6. Place the batch order and follow IQC, IPQC and OQC inspection through delivery.
