The Aquafilter FCCBKDF2 is a 10-inch slimline multi-media water filter cartridge combining coconut-shell granular activated carbon (GAC), KDF® media and ion-exchange softening resin. Designed for compatible standard 10-inch filter housings, it helps reduce chlorine, improve water taste and odour, and reduce water hardness.

Unlike a conventional activated carbon cartridge, the FCCBKDF2 combines three different filtration media to provide complementary treatment processes in one cartridge.

Three filtration media in one cartridge

The FCCBKDF2 contains three principal media:

1. Coconut-shell granular activated carbon (GAC)

The activated carbon helps reduce free chlorine and selected organic compounds that can affect water taste and odour. It also helps reduce certain solvents and organic substances.

2. KDF® media

KDF uses an oxidation-reduction (redox) process to help reduce chlorine and selected dissolved contaminants, including certain heavy metals, iron and hydrogen sulphide. It also helps inhibit bacterial growth within the filtration media.

3. Ion-exchange softening resin

The ion-exchange resin helps reduce water hardness by exchanging calcium and magnesium ions. This can help reduce the hardness contribution of the incoming water, although the cartridge has a finite softening capacity and is not a replacement for a dedicated whole-house water softener.

Designed for standard 10-inch slimline housings

The FCCBKDF2 measures approximately 9 7/8 inches long and 2.5 inches in diameter.

It is designed for compatible standard 10-inch slimline filter housings. It is not suitable for Big Blue housings, which require larger cartridges measuring approximately 4.5 inches in diameter.

Check your existing cartridge dimensions and housing compatibility before ordering.

Manufacturer performance figures are based on defined test conditions. Actual cartridge life and treatment performance depend on incoming water quality, hardness, chlorine concentration, flow rate and water consumption.

What can the FCCBKDF2 help reduce?

The combination of filtration media is designed to provide several water-treatment benefits:

• Chlorine reduction: Activated carbon and KDF help reduce free chlorine.

• Taste and odour improvement: Coconut-shell activated carbon helps reduce substances responsible for unpleasant tastes and smells.

• Selected organic compounds: Activated carbon helps reduce certain organic contaminants, including selected solvents.

• Selected heavy metals: KDF media helps reduce certain dissolved metals under suitable operating conditions.

• Iron and hydrogen sulphide: KDF media is designed to help reduce these substances.

• Water hardness: Ion-exchange resin helps reduce calcium and magnesium ions.

The degree of reduction depends on the concentration of contaminants and the operating conditions. This cartridge is not a universal contaminant-removal solution and should not be considered a substitute for microbiological disinfection.

Water softening performance

The FCCBKDF2 includes 0.15 litres of ion-exchange resin to help reduce calcium and magnesium, the principal contributors to water hardness.

Aquafilter specifies a maximum ion-exchange capacity of 0.45 m³ × °dH for this model. Its catalogue also gives a softening performance test figure of 200 litres under specified conditions, including water hardness of 2°dH.

This is a relatively small softening capacity compared with a dedicated water softener. The cartridge is best understood as a combined filtration and limited-capacity softening solution rather than a replacement for a full water-softening system.

Up-flow filtration design

The FCCBKDF2 belongs to Aquafilter's ACC-3 GAC/KDF cartridge range. These cartridges use an up-flow arrangement, allowing water to travel from the bottom upwards through the filtration media.

This design provides extended contact time between water and the media, supporting the adsorption and treatment processes.

Non-woven polypropylene layers help retain the filtration media inside the cartridge and prevent it from being washed out.

Installation and maintenance

Install the FCCBKDF2 in a compatible standard 10-inch slimline filter housing, following the housing manufacturer's instructions.

Aquafilter recommends installing a suitable sediment pre-filter upstream. Compatible FCPS or FCPP sediment cartridges can help capture suspended particles before water reaches the GAC, KDF and softening media.

The recommended replacement interval is 3–6 months. Replace the cartridge sooner if water quality, flow or usage indicates that it is exhausted.

Flush the cartridge before use according to the manufacturer's instructions.

This cartridge is designed for cold potable water. Do not use it with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the filtration system.
