Carbon Filter Cartridges

Pentair offers the widest choice of high-quality carbon filter cartridges for effective reduction of chlorine, taste and odour.

Pentair Carbon Filter Cartridges

Superior Water Purification with Activated Carbon

Pentair carbon filter cartridges represent the latest generation of activated-carbon filter technology for superior water purification. AQUA HUB GROUP is your partner for the complete range of Pentair carbon filters, from standard chlorine removal to advanced PFAS reduction. These filters are developed in Pentair's state-of-the-art research facilities and produced to the highest quality standards for drinking-water applications.

The Pentair CFB-Plus Series with Fibredyne technology is the most advanced carbon filter in the range. Fibredyne combines high-quality activated carbon with a unique fibre-matrix structure that provides a larger contact surface and more efficient adsorption. This results in superior removal of chlorine, chlorine taste and odour, organic contaminants and a wide range of chemical contaminants. CFB-Plus cartridges are available in various lengths and diameters for compatibility with standard filter housings.

The FloPlus Series with Fibredyne technology offers comparable performance in a design optimised for higher flow capacities. These cartridges are ideal for whole-house filtration and commercial applications where both water quality and flow rate matter. FloPlus filters combine excellent filtration results with a low pressure drop, resulting in optimum system efficiency and lower energy costs.

Activated-carbon filtration works on the principle of adsorption, whereby contaminants are bound to the enormous internal surface area of the carbon. Pentair uses only high-quality coconut-shell carbon or coal-based activated carbon, selected for optimum performance in specific applications. Fibredyne technology increases efficiency by embedding the carbon in a special fibre structure that ensures even water flow and maximum contact with the filter media.

Pentair carbon filters are certified to NSF/ANSI standards for drinking-water purification and comply with all European regulations for materials in contact with drinking water. The certifications cover the removal of specific contaminants, including chlorine, volatile organic compounds (VOCs) and, in the case of specialised filters, heavy metals and PFAS compounds.

In addition to the Fibredyne series, Pentair also offers traditional granular activated carbon (GAC) filters and pressed carbon blocks for specific applications. Each filter type has its own advantages: GAC filters offer a low pressure drop and high flow rates, while carbon blocks offer finer filtration and better removal of microbiological contaminants.

At AQUA HUB GROUP, we help you select the optimum carbon filter for your water-quality requirements. Whether you want to remove chlorine for better taste, reduce organic contaminants or need specialised PFAS treatment, we supply the Pentair solution that meets your needs.

Frequently asked questions about Pentair Carbon Filter Cartridges

What is Fibredyne technology and why is it better?
Fibredyne is Pentair's patented technology in which high-quality activated carbon is integrated into a special fibre matrix. This provides a larger contact surface between water and carbon, more efficient adsorption of contaminants and more consistent filtration quality throughout the entire service life of the cartridge. Fibredyne filters outperform traditional granular carbon filters.
How long does a Pentair carbon filter cartridge last?
The service life of a carbon filter depends on water quality and consumption. On average, a residential Pentair carbon filter lasts 6 to 12 months, or can treat 10,000 to 40,000 litres of water depending on the model. With high concentrations of chlorine or organic substances, the service life may be shorter. Replace the filter when you notice a decline in water quality or flow rate.
Which substances does a Pentair carbon filter remove?
Pentair carbon filters are effective against: chlorine and chlorine by-products, taste and odour compounds, organic contaminants, some pesticides and herbicides, and volatile organic compounds (VOCs). Specialised filters such as the FloPlus Protect can also reduce PFAS compounds. Carbon filters do not remove minerals, salts or microbiological contaminants.
What is the difference between CFB-Plus and FloPlus filter cartridges?
Both series use Fibredyne technology, but are optimised for different applications. CFB-Plus (Carbon Filter Block Plus) offers maximum chlorine and taste removal in a compact format. FloPlus is designed for higher flow capacities with minimal pressure drop, ideal for whole-house filtration. The choice depends on your specific requirements in terms of flow rate and filtration quality.
Can a carbon filter remove bacteria?
Standard carbon filters are not designed to remove bacteria and offer no microbiological protection. For bacteria-free water, you should consider additional treatment such as UV disinfection or ultrafiltration. Please note: an exhausted carbon filter can even promote bacterial growth, which is why timely replacement is essential.
Should I flush a carbon filter before first use?
Yes, when installing a new carbon filter, we recommend flushing the system for a few minutes until the water runs clear. This removes any carbon fines released during first use. The flushing water may look dark due to carbon particles; this is normal and harmless. After flushing, the water is immediately fit for consumption.
What do the different micron ratings of carbon filters mean?
The micron rating indicates the particle size the filter can retain. A 5-micron filter retains particles larger than 5 microns, while a 1-micron filter filters more finely. Finer filtration offers better protection but can lead to faster clogging. For most drinking-water applications, 5–10 microns is a good balance between filtration and service life.
Why does my water sometimes smell of sulphur after filter installation?
A slight sulphur smell immediately after installation can occur with carbon filters containing silver-impregnated carbon (for bacteriostatic action) or due to a reaction with hydrogen peroxide in the water. This smell usually disappears after a few minutes of flushing. If the smell persists, it may indicate bacterial activity in the pipework and further diagnosis is needed.
Can I combine carbon filters with other filter types?
Yes, carbon filters are often combined with sediment filters in a multi-stage system. The sediment filter removes coarse particles and protects the carbon filter against premature clogging. For complete water purification, you can combine carbon filtration with UV disinfection, RO membranes or special media for specific contaminants.
Where can I buy Pentair carbon filter cartridges?
