Precision Data. Proven Performance.
GreenCore Carbon technical specifications are designed to give engineers, procurement teams, and system designers full confidence in performance and consistency. Our coconut-based activated carbon is tested to strict international standards, ensuring reliable adsorption efficiency, mechanical strength, and long service life across water treatment, air purification, and industrial filtration applications.
All GreenCore Carbon filters are manufactured to industry-standard sizes, ensuring compatibility with most residential, commercial, and industrial water filtration housings. They are designed as direct replacements for systems currently using coal-based carbon filters, making upgrades to high-performance coconut-based activated carbon simple, cost-effective, and seamless.
Core Performance Specifications –
Coconut-Based Activated Carbon
GreenCore coconut-based activated carbon is manufactured from 100% premium coconut shell, delivering exceptional filtration performance across water treatment applications. With an iodine number exceeding 1000 mg/g, it provides high adsorption capacity for chlorine, VOCs, and organic contaminants. Available in carbon block and granular (GAC) formats with a 5 µm nominal rating, it is ideal for residential, commercial, and industrial water filtration, taste and odour improvement, and purification systems.
Standard Product Specification Tables
Our standard specification tables provide clear, technical performance data for each GreenCore product. These specifications help engineers, installers, and procurement teams select the correct carbon solution based on filtration performance, system compatibility, and operational requirements.
Coconut vs Coal – Technical Comparison
Performance & Quality Comparison
| Parameter | Coconut-Based Activated Carbon (GreenCore) | Coal-Based Activated Carbon (Typical ~400 Iodine) |
|---|---|---|
| Base material | Renewable coconut shell | Non-renewable coal |
| Iodine number (mg/g) | 1000+ (premium adsorption capacity) | ~400 (medium–low adsorption capacity) |
| Micropore volume | High – optimised for VOCs & organics | Moderate – more macropores, less efficient |
| Micron rating | 5 µm nominal | Often ≥ 10 µm or not specified |
| Chlorine reduction | Excellent – longer breakthrough time | Moderate – earlier breakthrough |
| Taste & odour improvement | Superior, cleaner output | Acceptable but less consistent |
| Ash content | Low – cleaner filtrate, less dust | Higher – more fines and turbidity risk |
| Hardness (abrasion resistance) | High – low attrition, less media loss | Lower – more breakage and fines |
| Service life | Longer – extended change-out intervals | Shorter – more frequent replacement |
| Batch-to-batch consistency | High – controlled coconut sourcing | Variable, depending on coal grade & source |
Lifespan & Cost Efficiency
| Factor | Coconut-Based Carbon | Coal-Based Carbon |
|---|---|---|
| Filter change frequency | Reduced (longer service life) | Increased (shorter life) |
| Maintenance requirements | Lower – fewer blockages & fines | Higher – more sediment/dust issues |
| Total cost of ownership | Lower over time due to longer life | Higher over time due to frequent replacement |
| Performance stability | Stable across lifespan | More rapid performance drop-off |
Environmental & Sustainability Benefits
| Environmental Aspect | Coconut-Based Activated Carbon | Coal-Based Activated Carbon |
|---|---|---|
| Resource type | Renewable agricultural by-product | Non-renewable fossil resource |
| Deforestation impact | No trees cut – uses coconut shells | Often linked to mining & land disruption |
| CO₂ emissions in production | Lower – cleaner-burning feedstock | Higher – energy-intensive coal mining & burning |
| Waste generation | Reduced – harder carbon, less dust | More fines, higher waste during use |
| Sustainability profile | Strong – supports circular material cycles | Weak – finite resource, higher footprint |

Retrofit Compatibility – Upgrade Your System from
Coal to Coconut
GreenCore Carbon filters are manufactured to strict industry-standard dimensions, making them compatible with most existing water filtration housings. This allows an easy, cost-effective upgrade from coal-based filters to high-performance coconut carbon.
- 10" and 20" Slimline Filters: Drop-in compatible with the majority of domestic and light commercial housings previously using coal-based cartridges.
- 10" and 20" Big Blue Filters: Designed for standard Big Blue housings in whole-house and high-flow systems.
- Bulk Granular Activated Carbon (GAC): Can refill vessels and cartridges previously filled with coal-based GAC, delivering superior adsorption performance.
In most cases, systems using 10″ or 20″ slimline or Big Blue coal-based filters can be upgraded without modifying the housing. For proprietary or specialised systems, confirm housing dimensions or contact our technical support team for guidance.
