What is the difference between activated carbon fiber cloth and felt?
Activated carbon fiber cloth and activated carbon fiber felt are two different flexible ACF media forms. ACF cloth is supplied as thin roll, sheet or cut-part material. The ACF felt in the supplied factory catalog is a viscose-based fibrous felt supplied in rolls or sheets. Their formats, listed specifications and conversion discussions are not interchangeable.
Both materials may be evaluated for adsorption-related components, but the correct choice depends on the actual product model, target pollutant, layer structure, dimensions, airflow, operating environment and validation method. Neither product name alone proves suitability for a finished filter or end-use claim.
Quick selection summary
| If the project needs... | Material to evaluate first | Information to confirm |
|---|---|---|
| A thin flexible ACF layer supplied as roll, sheet or custom-cut part | ACF cloth | Basis weight, width, cut dimensions, layer structure and intended application |
| A viscose-based fibrous felt with a catalog thickness range | ACF felt | Thickness, density, width, component structure and target VOC or odor source |
| A converted multilayer or cartridge component | Evaluate the finished structure | Drawing, sample, airflow, installation space, conversion and test requirements |
This table is a starting point for sample discussion. Final selection must be based on the exact model and finished-product design.
Material 01
Activated Carbon Fiber Cloth
Activated carbon fiber cloth, also called ACF cloth, is a thin flexible activated carbon fiber adsorption medium. It can be discussed as roll, sheet or converted cut-part material for air-purification, protective-product and adsorption-component projects.
- Supply form: roll, sheet or cut part
- Material: activated carbon fiber cloth
- Catalog specific surface area: 900–1200 m²/g
- Catalog basis weight: 80–350 g/m²
- Customization discussion: basis weight, width, dimensions and converted shape
The two catalog ranges describe the product series. They do not mean that every basis-weight and specific-surface-area combination is available in one model, and they do not independently confirm removal performance in a finished product.
Material 02
Activated Carbon Fiber Felt
Activated carbon fiber felt, or ACF felt, is a flexible fibrous adsorption medium. The supplied catalog identifies it as viscose-based activated carbon fiber felt for VOC adsorption, odor control and converted industrial filtration components.
- Supply form: roll or sheet
- Material: viscose-based activated carbon fiber felt
- Catalog fiber diameter: 10–20 μm
- Catalog tensile strength: >5 kg/m
- Catalog thickness: 0.8–4.5 mm
- Catalog bulk density: 0.05–0.08 g/cm³
- Catalog ash content: <2%
These values are product-series references. The selected felt model, dimensions, conversion structure and order specification must be confirmed before quotation or performance discussion.
ACF cloth vs. ACF felt comparison
| Selection factor | ACF cloth | ACF felt |
|---|---|---|
| Basic material form | Thin, flexible activated carbon fiber cloth | Viscose-based fibrous activated carbon felt |
| Supply format | Roll, sheet or cut part | Roll or sheet |
| Catalog values provided | Specific surface area and basis weight | Fiber diameter, tensile strength, thickness, bulk density and ash content |
| Catalog range highlights | 900–1200 m²/g; 80–350 g/m² | 10–20 μm; >5 kg/m; 0.8–4.5 mm; 0.05–0.08 g/cm³; <2% ash |
| Listed application direction | Air purification, protective products and adsorption components | VOC adsorption, odor control and industrial filtration |
| Conversion discussion | Width, cut dimensions, layer structure and converted shape | Thickness, density, width, layering and component conversion |
The catalog lists different properties for the two materials. The absence of the same test item on both product pages prevents a complete numerical performance ranking. Compare actual samples under the intended finished-product structure and applicable test method.
How should a buyer choose between ACF cloth and felt?
- Define the application. Identify the equipment, finished product and location of the ACF layer.
- Name the target pollutant. State the odor, VOC or other gas-phase contaminant to be evaluated.
- Choose the required material format. Specify roll, sheet, cut part, layered component or cartridge structure.
- Provide physical requirements. Include width, length, thickness or basis weight, cut shape and available installation space.
- Describe operating conditions. Share airflow, temperature, humidity and any other known environmental conditions.
- State the validation requirement. Identify the test method, finished-product claim or customer standard that must be reviewed.
If the project starts from an existing component, a drawing or physical sample is more useful than selecting from a material name alone.
Frequently asked questions
Is activated carbon fiber cloth the same as activated carbon fiber felt?
No. Both belong to the activated carbon fiber media family, but they are different material forms. ACF cloth is supplied as thin roll, sheet or cut-part media; the catalog-listed ACF felt is a viscose-based fibrous felt supplied in rolls or sheets.
Which is thinner, ACF cloth or ACF felt?
The cloth series is described as thin and flexible, while the felt catalog lists a thickness range of 0.8–4.5 mm. The cloth catalog page does not provide a thickness range, so the exact models must be compared before making a numerical thickness claim.
Can the catalog values be compared directly?
Not as a complete performance ranking. ACF cloth is listed by specific surface area and basis weight. ACF felt is listed by fiber diameter, tensile strength, thickness, bulk density and ash content. Different listed properties do not prove that one material performs better in a finished filter.
Which material is suitable for VOC control?
The ACF felt catalog lists VOC adsorption and odor-control applications. ACF cloth is listed for air purification and adsorption components. Suitability for a specific VOC, airflow or service-life target must be verified using the selected model, finished structure and applicable test method.
What information is needed before requesting samples?
Send the target application and pollutant, required material format, dimensions, thickness or basis weight, layer structure, airflow and operating conditions, conversion method, quantity and any available drawing, sample or test requirement.
