The Thesvin plate-type activated carbon cloth filter is a flat panel filter that combines high-iodine-value honeycomb activated carbon with a proprietary formaldehyde-removal catalyst composite to adsorb and catalytically break down HCHO, benzene-series compounds and TVOC in air. It is built for household air purifiers, fresh-air systems, vehicle cabin air filters and commercial or industrial odour-control equipment, and it is supplied as a plate composite, honeycomb-filled panel or sintered carbon block, including custom shapes. Thesvin manufactures it in Zhongshan, Guangdong, China, with dimensional control backed by IATF 16949 and IQC/IPQC/OQC inspection.
Fitment comes first on this part. A plate filter only performs when the frame sits flush against the host housing, the panel edge seats against the gasket line, and the airflow path passes through the carbon layer rather than around it. Thesvin works from your existing filter dimensions or a drawing, so the panel outline, thickness and edge profile are matched to the slot in the air purifier, fresh-air unit, cabin housing or duct section where the filter locates.
The construction is a flat composite panel with a carbon layer sandwiched in the filter media, so the part stays rigid enough to slide into a guided track and hold its shape under negative pressure. Because the panel is not a deep-pleat cartridge, it suits housings with shallow filter bays and front-loading access. Honeycomb-filled and sintered carbon block variants are available where the housing has deeper clearance and a heavier carbon load is needed.
Custom shapes are supported. That matters where the host device has cut-outs for sensors, handles or wiring, or where a duct transition requires a stepped outline. Send the old part or the drawing and Thesvin will confirm the outline, thickness and carbon loading before tooling or cutting begins.
The working media is high-iodine-value honeycomb activated carbon combined with a formaldehyde-removal catalyst composite. The carbon adsorbs odour and solvent vapours, while the catalyst composite supports catalytic decomposition of formaldehyde. The target gases are HCHO, benzene-series compounds and TVOC, which covers the common indoor and cabin odour mix as well as process exhaust from spray booths and similar odour-generating operations.
Typical applications fall into two groups. Household uses include air purifiers, pre- and high-efficiency stages in fresh-air systems, and vehicle cabin air filters. Commercial and industrial uses include hospital cleanrooms, industrial waste-gas treatment and odour-control equipment. In fresh-air systems the panel can serve as a gas-stage filter behind a particulate stage, depending on how the system is designed.
The filter is aimed at buyers who need gas and odour control in a flat, replaceable panel rather than a deep bed of loose carbon. If the target is particulate capture only, a panel HEPA format from the same family is the more direct choice; the activated carbon cloth panel is specified where the gas load drives performance.

Dimensions, carbon loading and frame format are made to the host device. Thesvin does not publish a single fixed size for this product because the panel is built to the fitment you specify.
Dimensional consistency is the quality issue that matters most on a plate filter, because a panel that is a few millimetres out will not seat. Thesvin runs IATF 16949, obtained in 2024, and applies IQC, IPQC and OQC control across the production flow so incoming carbon, in-process panels and outgoing batches are checked against the approved drawing.
Testing is carried out at the company's own CNAS-accredited laboratory, which can issue reports on filtration efficiency, dust holding capacity and resistance. The plant covers 50,000 m², including 6 clean workshops with a combined area of 20,000 m². The management system holds ISO 9001, ISO 14001 and ISO 45001 certification, and products meet REACH and RoHS requirements with compliance documents available on request.
Thesvin has more than 20 years of filtration research and manufacturing experience and has supplied export markets in Europe, the United States, Japan and Korea for over 20 years, with more than 1,000 filtration solutions developed to date. Multiple automated production lines support output in the millions of pieces per month, and OEM/ODM work covers size, structure, media grade, frame material, logo and packaging.
To get a quote, send the device or vehicle model, the size or a drawing, the airflow or water flow the filter sees, the operating conditions such as temperature and target gases, and the quantity you need. If you do not have a drawing, an old part is enough to start. Contact the team through /en/contact and include the details above so the first reply can be a concrete fitment and pricing proposal.
Fitment is matched to your host device: the Thesvin plate-type activated carbon cloth filter is built to the outline, thickness and edge profile of your existing filter bay or drawing, in flat plate composite, honeycomb-filled panel or sintered carbon block form. Custom shapes are supported for housings with cut-outs or stepped duct transitions. Send the device model and a drawing or old part, and the fitment is confirmed before production.
Yes. An old part is enough to start, because it shows the outline, thickness, locating edges and any cut-outs in the housing. Thesvin measures it and confirms the panel geometry with you before tooling or cutting. A drawing is welcome if you have one, but it is not a requirement for a first quote.
The core construction is high-iodine-value honeycomb activated carbon with a proprietary formaldehyde-removal catalyst composite, aimed at HCHO, benzene-series compounds and TVOC. The carbon adsorbs odour and solvent vapours while the catalyst composite supports catalytic decomposition of formaldehyde. Because carbon loading and structure can be specified, the panel is matched to the gas load in your application.
Yes. Size, structure, media grade, frame material, logo and packaging can all be customised under OEM/ODM, and custom shapes are supported. Thesvin has developed more than 1,000 filtration solutions and can confirm whether a plate composite, honeycomb-filled panel or sintered carbon block best suits your housing depth and airflow.
MOQ, sample policy and lead time for this product are confirmed with your inquiry, since they depend on the custom size and structure. Send the device model, size or drawing, airflow or water flow, operating conditions and quantity through the contact page. The team will reply with the MOQ, sample arrangement and price for the exact specification.
Delivery is quoted per order once the drawing and quantity are fixed, because custom panel size and carbon loading affect the production schedule. Thesvin runs multiple automated production lines in a 50,000 m² plant and holds IATF 16949 certification with IQC, IPQC and OQC control across the flow. Your confirmed lead time is stated in the quotation.
Replacement depends on the gas concentration, airflow and operating hours in your application, so the interval is set per installation rather than as a single figure. Because the panel is a gas-stage filter, it is normally changed on the schedule your maintenance plan sets for the host device. Thesvin can advise on a replacement interval once the operating conditions are known.
Send the device or vehicle model, size or drawing, airflow or water flow, operating conditions and quantity through <a href="/en/contact">/en/contact</a>. Including an old part photo or a drawing shortens the fitment check. The first reply will cover fitment, carbon structure and pricing for your specification.
