What is activated carbon filter media?
Activated carbon filter media is a family of adsorption materials and converted filter components used when a filtration product needs an odor-control or gas-phase adsorption stage. Factory product forms include carbon-containing nonwoven, activated carbon fiber cloth and felt, carbon foam, rolls, sheets, cut parts and assembled filters.
The product name alone is not enough for selection. Filter manufacturers and OEM buyers should compare the carrier structure, supply form, dimensions, conversion method, installation space, target odor or VOC, airflow and finished-product test requirement.
Two ways to source activated carbon filtration products
| Procurement path | Suitable for | What can be discussed |
|---|---|---|
| Raw filter media | Filter manufacturers, media converters and component producers | Rolls, sheets, basis weight or thickness, width, slitting, lamination and cut parts |
| Finished filters or components | Air-purifier, HVAC, ventilation and filtration-equipment projects | Dimensions, frame or housing structure, media combination, sealing, drawing or reference sample |
Manufacturing feasibility and final specifications are confirmed for the selected model and order. A finished-filter inquiry should include an existing part number, drawing or sample whenever available.
Activated carbon media types and supply formats
For polyester fibers carrying powdered activated carbon, see polyester-based activated carbon filter media in rolls, sheets and cut parts. This carrier-based material is distinct from activated carbon fiber (ACF) cloth and felt.
| Product family | Basic structure | Available discussion |
|---|---|---|
| Activated carbon nonwoven fabric | Activated carbon incorporated in a flexible nonwoven medium | Roll, sheet, width, dimensions and converted cut part |
| Activated carbon sandwich nonwoven | Granular carbon held between supporting nonwoven layers | Roll, sheet, cut pad, layer structure and conversion |
| Granular activated carbon nonwoven | Fibrous carrier containing activated carbon material | Roll or sheet dimensions and converted filtration layer |
| Activated carbon fiber cloth | Thin, flexible activated carbon fiber cloth | Roll, sheet, basis weight, width and cut part |
| Activated carbon fiber felt | Viscose-based activated carbon fiber felt | Roll, sheet, thickness, width, layering and component conversion |
| Activated carbon foam filter media | Open-cell polyurethane foam carrying powdered activated carbon | Foam sheet, thickness, pore density and custom-cut component |

Choosing rolls, sheets or cut parts
Once you have identified the material, decide who will do the cutting. Tell us whether you need stock for your own production or pieces supplied to a finished outline. Include dimensions with units and a quantity for each size.
The roll, sheet and cut-part buying guide explains what to specify for each format, including drawings, samples and packing. It compares supply formats, not adsorption performance or guaranteed production costs.
Custom finished activated carbon filters and components
Projects that do not need raw roll media can start from a finished component format. Current product directions include ACF composite pads, plastic honeycomb activated carbon filters, pleated activated carbon filters, activated carbon bag filters, flat-panel carbon filters and ACF filter cartridges.
Finished filters are reviewed against the buyer's existing part number, dimensions, drawing or sample, frame or housing requirement, carbon structure, quantity, packaging and test requirement. A match is confirmed only after factory feasibility review.
Information needed before quotation or sample selection
- End use or equipment type
- Target odor, VOC or gas-phase contaminant
- Required roll, sheet, cut-part or finished-filter format
- Dimensions, thickness or basis weight requirement, when known
- Airflow and operating temperature or humidity conditions
- Lamination, frame, sealing or assembly requirement
- Estimated quantity and any drawing, part number, sample or test method
If some values are not yet available, send the current product photo and installation information first. The factory can identify which existing product formats are relevant for further review.
A simple way to start your inquiry
Copy the prompts below into your message and fill in what you know. Leave unknown details open rather than guessing a material grade or performance value.
- Application and installation position:
- Existing material name, code or specification, if available:
- Supply format and dimensions, with units:
- Quantity for each size:
- Drawing, reference sample and test requirements, if available:
Send your carbon media requirement. If your inquiry is for white synthetic pre-filter media, use the separate white pre-filter RFQ checklist.
Frequently asked questions
What forms of activated carbon filter media are available?
Available factory product forms include activated carbon nonwoven, sandwich nonwoven, activated carbon fiber cloth and felt, activated carbon foam, rolls, sheets, cut parts and custom assembled filter components. The suitable form depends on the product structure and test requirement.
Can Junkang supply both raw filter media and finished carbon filters?
Yes. Junkang supplies raw filter media for converters and filter manufacturers, and also develops custom finished filters or components after reviewing dimensions, construction, application and manufacturing feasibility.
What is the difference between carbon nonwoven, ACF media and carbon foam?
Carbon nonwoven uses a nonwoven carrier or supporting layers. Activated carbon fiber media is supplied as carbon fiber cloth or felt. Carbon foam uses porous polyurethane foam carrying activated carbon. These structures require different conversion and installation discussions.
What information is needed for a quotation or sample?
Provide the application, target odor or VOC, required format, dimensions, quantity, airflow and operating conditions, plus any available drawing, part number, sample or test requirement.
Can one activated carbon media grade be used for every odor or VOC application?
No universal grade can be selected from the product name alone. The exact media model and finished structure must be evaluated against the target pollutant, airflow, operating environment, dimensions and applicable test method.
