Where Activated Carbon Filtration Is Required
When UV and ESP alone still leave residual odors, activated carbon provides the final polishing stage.

Why Activated Carbon Is Still Irreplaceable
ESP Removes Particles. UV Removes Odors. Carbon Removes Everything Else.
In the most demanding environments — hospitals, residential areas, luxury hotels — even ESP + UV may not achieve the “zero odor” standard demanded by regulators and stakeholders.
Activated Carbon: The Last Line of Defense
Premium coconut shell activated carbon has billions of micro-pores that trap the smallest VOC molecules through physical and chemical adsorption. It catches what UV misses and ensures truly clean exhaust.
- Adsorbs residual VOCs, aldehydes, and trace cooking odors
- Complementary to ESP (particles) and UV (photolysis)
- Required by regulations in many EU, UK, and APAC markets
- Drawer-type panels for easy 5-minute replacement
- Premium coconut shell carbon for maximum adsorption capacity
- Ideal for “zero odor” applications near sensitive populations
Why Choose Polygee Carbon Filters
Engineered specifically for commercial kitchen exhaust, not adapted from industrial HVAC.
Coconut Shell Carbon
Premium coconut shell activated carbon with higher iodine value and larger surface area than coal-based carbon.
Drawer-Type Panels
Slide-out carbon panels. No tools required. 5-minute replacement. Minimal downtime for kitchen operations.
Modular Frame
304 stainless steel frame. Stack multiple units for higher airflow. Connect directly to ESP and UV modules.
Multiple Carbon Types
Standard, impregnated, and honeycomb carbon options for different VOC types and odor levels.
Low Pressure Drop
Optimized airflow design minimizes static pressure loss. Your existing fan may not need upgrading.
Easy Inspection
Transparent inspection window. Visual indicator for carbon saturation level. Know when to replace.
Eco-Friendly Disposal
Spent carbon can be regenerated or disposed of as non-hazardous waste (check local regulations).
OEM / ODM Available
Custom frame sizes, carbon types, and panel configurations for distributors and system integrators.
How Activated Carbon Adsorption Works
A simple physical process that traps gaseous pollutants in billions of microscopic pores.
Pre-Filtered Air Enters
After ESP removes grease/smoke and UV breaks down odors, remaining air with trace VOCs enters the carbon unit.
→Carbon Adsorption
Air passes through activated carbon panels. VOC, aldehyde, and odor molecules are trapped in carbon pores via Van der Waals forces.
→Near-Zero Odor Exhaust
Purified air exits with virtually no detectable odor. Meets the strictest residential and commercial emission standards.
When to Use Carbon vs. UV vs. ESP
✅ Activated Carbon (Final Stage)
Best for: residual VOCs, trace odors, applications near hospitals and residences. Physical adsorption. Simple replacement cycle. No electricity needed. Works passively.
✅ Best When Combined
Carbon works best as Stage 3 after ESP (Stage 1) and UV (Stage 2). Pre-filtering extends carbon life by 3–5x. Without pre-filtration, carbon saturates within weeks.
💡 UV-C Photolysis (Stage 2)
Best for: breaking down strong cooking odors actively. Zero consumables. But cannot capture all VOC types — some molecules resist photolysis.
⚡ ESP (Stage 1)
Best for: grease and smoke particles. Does not remove gaseous odors at all. Essential pre-filter for both UV and carbon to function properly.
Carbon as Part of a Multi-Stage System
Activated carbon delivers maximum performance when positioned as the final purification stage.
ESP — Grease & Smoke Removal
Electrostatic precipitator removes 95–99% of grease particles. Critical pre-filter to prevent carbon from clogging.
UV-C — Odor Decomposition
UV photolysis breaks down most VOCs and cooking odors. Reduces carbon load by 60–80%.
Carbon — Final Odor Polish
Activated carbon adsorbs remaining trace VOCs. Achieves near-zero odor exhaust for sensitive locations.

Request Custom Carbon Filter →Installation Options for Carbon Filter
Simple installation downstream of UV and/or ESP units.
Inline with ESP + UV
Mount carbon unit after UV module in the duct run. Standard flange connections. Most common setup.
Plant Room Installation
For large systems, install in dedicated plant room alongside ESP and UV. Easy access for carbon replacement.
Rooftop Unit
Weather-rated enclosure for outdoor/rooftop installations. Protects carbon from moisture.
Standalone Add-On
Can be added to any existing exhaust system — even non-Polygee ESP. Universal flange compatibility.
- Always install downstream of ESP and/or UV — never expose carbon directly to raw grease
- Carbon panels should be replaced every 3–6 months depending on cooking volume
- Use Polygee OEM carbon panels for guaranteed fit and adsorption performance
- Ensure access door on front or side for drawer-type panel replacement
- No electrical connection needed — carbon filtration is a passive process
- Store spare carbon panels in a dry, sealed environment to prevent pre-saturation
