Why HVAC systems use carbon filtration
HVAC and ventilation projects may require more than particle filtration. When the target includes odor, smoke-related smell, VOCs or gas-phase pollutants, activated carbon media is often considered as a supporting filtration layer or component.
The final format depends on the unit structure. Some customers need carbon sheets or pads, while others need carbon-loaded foam, framed panels, bag filters or custom assembled filters.

Suitable product options
- Activated carbon sandwich nonwoven media
- Activated carbon foam filter media
- Fibrous activated carbon filter media
- Cut-to-size carbon pads
- Framed carbon filter components
- Custom carbon filter assemblies
Information to send for a project
