This cylindrical activated carbon filter is a high-iodine-value carbon cartridge designed to adsorb formaldehyde, benzene, ammonia, TVOCs and odours from air streams. It is built for air purifiers, fresh-air systems, automotive cabin filters, central air handling units and industrial odour control. Ranveth pairs the carbon medium with a cylindrical layer build to balance efficiency, low airflow resistance and service life, and supports full customisation to your drawing or sample.
The core of this filter is a high-iodine-value activated carbon, available in coconut-shell or coal-based grades with iodine values from 800 to 1200 mg/g. The carbon is arranged in a cylindrical form that gives a large adsorption surface within a compact footprint, so the air path is kept open and resistance stays low. That pairing of medium and geometry is what drives the filter's efficiency: the carbon does the adsorbing, and the cylindrical layer build gives the air an even, low-resistance route through the media.
For buyers, the practical effect is a filter that can deliver strong VOC and odour removal without imposing a heavy load on the fan. Lower resistance supports the energy efficiency of the host device, while the carbon grade and fill weight can be tuned to the contaminant profile and target life. The structure can be supplied in honeycomb or granular form, with end caps in metal, plastic or paper, and with optional functional coatings for formaldehyde, antibacterial or ozone removal. Every media choice is made against test data, so the pairing is not guesswork.

The cylindrical format suits devices with a round filter seat and a compact internal volume. Typical installations include portable and whole-room air purifiers, where the cartridge handles odours and VOCs; fresh-air systems, where it can serve as a pre-filtration stage; automotive cabin filters; central air-conditioning systems; and industrial waste-gas deodorisation. In each case the carbon grade, fill weight and end-cap material are selected to match the airflow, contaminant load and target replacement interval of the host equipment.
To quote a custom cylindrical carbon filter, send the device or vehicle model, the required size or a drawing, the airflow or water flow the filter will see, the operating conditions (temperature, humidity, contaminant type and concentration), the quantity you expect per order, and any end-cap, coating or packaging requirements. With these details our engineers can propose the carbon type, iodine value and layer build, and provide a sample for validation. OEM/ODM support covers dimensions, structure, media grade, frame material, logo and packaging.
Ranveth is backed by a manufacturer with a CNAS-accredited laboratory that issues test reports for filtration efficiency, dust holding capacity and resistance, so media choices are test-backed. The production base covers 50,000 m², including six cleanrooms totalling 20,000 m², and the quality system holds IATF 16949 (obtained in 2024) as well as ISO 9001, ISO 14001 and ISO 45001. Products meet REACH and RoHS requirements, with compliance documents available. More than 20 years of filtration R&D and manufacturing experience, with over 20 years of continuous export to Europe, the United States, Japan and South Korea, supports stable supply. OEM/ODM programmes have developed more than 1,000 filtration solutions, and multiple automated lines support monthly output in the millions of pieces, with IQC, IPQC and OQC controls throughout. The company is located in Zhongshan, Guangdong, China.

The filter uses high-iodine-value activated carbon, available in coconut-shell or coal-based grades with iodine values of 800–1200 mg/g, arranged in a cylindrical layer build. Optional functional coatings can be added for formaldehyde, antibacterial or ozone removal.
The cylindrical form gives a large adsorption surface in a compact space, so air passes evenly through the carbon with low resistance. This pairing supports strong VOC and odour removal while keeping fan load low, which helps device energy efficiency.
Under normal operating conditions the filter life is 6–12 months, depending on contaminant concentration and airflow. The carbon grade and fill weight can be tuned to your target replacement interval.
Yes. We customise inner and outer diameter, height, carbon type and weight, honeycomb or granular structure, and end caps in metal, plastic or paper. Logo printing and retail packaging are also available, and we can develop 1:1 from your drawing or sample.
Standard models typically have an MOQ of 500–1000 pcs, while custom models are generally 2000–3000 pcs depending on complexity. Standard stock ships in 3–7 days; custom batches ship about 15–25 days after sample approval.
Samples are available for validation. Standard specification samples are usually free with the customer covering international courier cost; custom samples carry a development fee that is deductible from a bulk order. Send your specifications to receive a quotation.
Our CNAS-accredited laboratory can issue reports for filtration efficiency, dust holding capacity and resistance. These reports back the carbon grade and layer build selected for your application.
Please provide the device or vehicle model, required size or drawing, airflow, operating conditions, quantity and any end-cap or packaging requirements. <a href="/en/contact">Contact us</a> with these details to receive a tailored proposal.
