Two Carbon Technologies — One OEM Partner
Granular Carbon Filters
Loose granular activated carbon (GAC) packed into a mesh frame provides maximum carbon residence time and superior odor/VOC removal. Ideal for heavy-duty applications where pollutant concentrations are high — industrial settings, commercial kitchens, and pet households.
Best for: Maximum adsorption capacity
Honeycomb Carbon Filters
Carbon impregnated into a structured honeycomb matrix offers low air resistance with consistent, even airflow distribution. The honeycomb geometry maximizes contact surface while keeping pressure drop minimal — ideal for residential air purifiers requiring both quiet operation and efficiency.
Best for: Low-resistance air purifier use
Pollutants Our Carbon Filters Remove
OEM for Leading Air Purifier Brands
We supply custom carbon filters to major air purifier brands globally. Our engineering team can optimize carbon density, granule size, and filter dimensions to your exact CAD drawings. Nantong Deli's patented High-Efficiency Removal Device technology ensures our carbon filters lead the industry in formaldehyde and VOC reduction performance.

Understanding the science behind activated carbon filtration helps OEM buyers specify the right product — and explain the value to their end customers.
How Adsorption Works
Activated carbon removes pollutants through adsorption — a surface-chemistry process where gas molecules bond to the porous surface of carbon particles. Unlike filtration (which physically traps particles), adsorption captures molecules at the atomic level. A single gram of activated carbon has a surface area of 500–3,000 m² — enough to trap formaldehyde, benzene, toluene, VOCs, and odor molecules far below detectable thresholds. Nantong Deli's patented High-Efficiency Removal Device geometry maximizes air-to-carbon contact time, increasing adsorption efficiency per unit volume compared to standard designs.
Granular vs. Honeycomb Carbon — The OEM Choice Guide
Granular Activated Carbon (GAC)
- Maximum adsorption capacity
- Best for high-concentration pollutant environments
- Ideal for kitchen range hood inserts, industrial air cleaners
- Higher pressure drop — requires adequate fan power
- Carbon can be replaced when exhausted
Honeycomb Carbon Block
- Low air resistance — quiet operation
- Consistent efficiency across the filter face
- Ideal for residential air purifiers (CADR-sensitive designs)
- Structural — easy to slot into cartridge frames
- Available in custom thicknesses and densities
Both types are available in custom dimensions. Tell us your filter cavity size, target pollutants, and airflow specification — our engineers will recommend the carbon grade, density, and form factor for your product.
