Ranveth adhesive-bonded activated carbon filter mesh is an odor-removal filter built by fixing high-iodine-value carbon granules onto a substrate with an environmentally compatible binder. It adsorbs formaldehyde, benzene, ammonia and other volatile organic compounds (VOCs) from air, and is supplied to air purifier, range hood, air fryer, commercial HVAC and pet-care appliance makers as a custom-sized component. The filter is designed for buyers who need to match adsorption performance, airflow resistance and service life within a defined device envelope.
The core of this filter is a layer of premium high-iodine-value activated carbon granules held in an adhesive-bonded structure on a green substrate. The iodine value of the carbon reaches 800–1100 mg/g, a measure of available micropore surface for capturing gas-phase contaminants. The granules are distributed across the substrate rather than packed into a rigid honeycomb block, which lets the carbon layer follow flat, folded or shaped formats without changing the chemistry of adsorption.
This pairing matters because performance is not set by carbon alone. The substrate carries the granules and defines the mechanical shape; the binder fixes them in place; the carbon grade determines which molecules are captured and how quickly. A denser carbon loading can raise initial removal efficiency but also raises airflow resistance. A lighter loading keeps pressure drop low but shortens the time before breakthrough. Ranveth treats these as one design decision, not three separate specifications.
In service, the bonded layer presents a large exposed carbon surface to the airstream while keeping the overall filter thin. Lower resistance reduces the load on the fan and supports energy-efficient operation. The same construction can be combined with pre-filter or HEPA media in a multi-stage panel, so the carbon stage handles gases and odors while the particle stage handles dust. For washable range-hood variants, the bonded format allows surface cleaning without dislodging the carbon layer, although gas capacity still declines with use and the filter should be replaced on the interval agreed for the application.
The practical result is a filter whose efficiency, pressure drop and life can be tuned by adjusting carbon grade, loading weight and substrate format. Buyers specifying this product should treat those three variables as the levers for meeting a target pressure-drop budget or a target replacement interval.

This filter is specified where gaseous contaminants and odors need to be removed from an airstream without adding a large pressure penalty. Typical installations include household and commercial air purifiers, fresh-air ventilation systems, automotive cabin filters, central air-conditioning units and vacuum cleaner exhaust filters. The same bonded carbon media is used in range-hood and integrated-stove odor filters, air fryer and deep-fryer odor filters, cat litter box odor filters, and ozone-removal or TVOC-removal stages in room air conditioners.
The common thread across these applications is a defined air path and a target gas. A purifier may focus on formaldehyde and TVOC from furnishings; a range hood focuses on cooking odors and oil smoke; a pet appliance focuses on ammonia and sulfur compounds. Because the carbon grade and loading can be changed, Ranveth can supply one construction family across several product lines while the media inside is matched to each duty.
A custom quotation starts from the device, not from a catalogue number. Please send the following with your inquiry so engineering can respond with a concrete proposal:
With these inputs, Ranveth can select a carbon grade and loading weight, propose a layer build, and confirm whether the target pressure drop and life are achievable in the available space. If the target gas is unusual, the CNAS-accredited laboratory can run adsorption tests against that specific contaminant.
Ranveth is a filter manufacturer based in Zhongshan, Guangdong, China, with more than 20 years of filtration research and manufacturing experience and continuous exports to Europe, the United States, Japan and South Korea. The company operates its own laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports covering filtration efficiency, dust holding capacity and resistance. For a carbon filter, that means media choices can be backed by measured data rather than assumption.
The production base covers 50,000 m², including six cleanrooms with a combined area of 20,000 m². Quality management runs through IQC, IPQC and OQC, and the company holds IATF 16949 (obtained in 2024) as well as ISO 9001, ISO 14001 and ISO 45001 system certifications. Products meet REACH and RoHS requirements, and compliance documentation can be supplied. Multiple automated production lines support monthly output in the millions of pieces, and the company has developed more than 1,000 filtration solutions, with OEM/ODM support for size, structure, media grade, frame material, logo and packaging.
To evaluate this adhesive-bonded activated carbon filter for your device, send the device model, a size drawing or sample, the airflow or water flow, your operating conditions and the quantity you expect to order. Ranveth will reply with a proposed media pairing, a quotation and the next steps for sampling. You can reach the team through the contact page.
It uses premium high-iodine-value activated carbon granules, with an iodine value of 800–1100 mg/g, fixed onto an environmentally compatible substrate by an adhesive-bonded process. The carbon captures formaldehyde, benzene, ammonia and other VOCs, while the substrate and binder define the filter's shape and mechanical stability.
The bonded layer exposes carbon granules across a thin, open structure, which keeps airflow resistance low and reduces fan energy use. Efficiency is set mainly by carbon grade and loading weight: higher loading raises initial removal but also pressure drop, so the two are balanced during specification.
Yes. Sizes, shapes and frame materials are custom-made, and the carbon grade and loading can be adjusted to suit the target gas and available space. Ranveth supports OEM/ODM including logo and packaging, and has developed more than 1,000 filtration solutions.
For this product, standard configurations typically start at 1,000–3,000 pieces, while customised builds generally start at 3,000–5,000 pieces. Standard items ship in 7–15 days; custom sampling takes 7–10 working days and mass production 25–35 days.
Samples are available for evaluation. Standard sizes can be supplied free of charge with the courier cost covered by the customer, while custom samples may carry a development fee that is refundable against a mass-production order. Samples can be accompanied by CNAS laboratory test data.
Service life is typically 6–12 months, depending on contaminant concentration, running hours and airflow. In a standard household duty of about 8 hours per day, 6–8 months is a common replacement interval; commercial high-load duty may call for 3–6 months.
The CNAS-accredited laboratory can run adsorption tests against a target contaminant and provide data on efficiency and breakthrough behaviour. This allows the carbon grade and loading to be matched to the gas you need to remove.
