Aquafilter FP3-K1N is a 3-stage under-sink water filter with a carbon cartridge containing KDF. The set includes: a mechanical filter FCPS5 (up to 5 µm), a conditioning cartridge FCCST2 (softening and iron reduction), and a cartridge FCCBKDF (chlorine reduction, organic compounds and heavy metals, improving taste and odor). The complete set also includes a separate faucet with a ceramic head and mounting accessories.
FP3-K1 AQUAFILTER under-sink water filter KDF is a 3-stage water filtration system for installation under the sink, designed for everyday water treatment in the kitchen. The set combines a mechanical filter, a softening and iron-removal cartridge, and a carbon cartridge with KDF, helping reduce sediment, chlorine, iron, selected organic compounds and heavy metals, while also improving the taste and smell of the water. This is a practical water filter for anyone looking for a convenient under-sink solution and an effective water filtration system for the kitchen. The set also includes a separate chrome tap with a ceramic valve and installation accessories.

The FP3-K1N model has been designed as a compact under-sink system that purifies water in stages. Thanks to the use of three different filter cartridges, the water passes through successive treatment phases, and each filter cartridge is responsible for a different scope of work.
The system includes the FCPS5 cartridge, which removes mechanical impurities such as sand, silt and suspended solids up to 5 µm, the FCCST2 cartridge that reduces iron concentration and water hardness, and the FCCBKDF carbon cartridge, which removes chlorine, pesticides and organic substances, reduces the concentration of heavy metals, improves the taste and smell of the water, and has bacteriostatic properties.
This solution is suitable where ease of use, better drinking and cooking water quality, and everyday water treatment matter, without the need to choose systems such as reverse osmosis or an osmosis filter.


The set includes a spout with a ceramic head, designed for convenient dispensing of filtered water.

FP3-K1N is a high-quality device that has been tested, checked and verified to meet approval and quality assessment requirements.
Water Regulations Advisory Scheme is a conformity mark confirming compliance with the high standards set out in the Water Supply (Water Fittings) Regulations in England and Wales, as well as equivalent water regulations in Scotland and Northern Ireland. These regulations cover the design, installation, operation and maintenance of water installations, water fittings and water-using devices, playing an important role in protecting public health, securing water supply and promoting efficient water use.

NSF International is an American organization operating since 1944. It is an independent, non-profit product testing and certification agency that sets standards for a wide range of household and industrial products. Products marked with the NSF symbol undergo rigorous inspection procedures that are periodically repeated and confirmed.
The device was manufactured in the European Union.

The compact design makes it easy to install under the sink and helps organize the work space in the kitchen cabinet.
The system is installed under the sink using the included accessories and a separate tap for filtered water. To maintain proper filtration performance, the device should be used in accordance with the operating instructions and the filter cartridges should be replaced regularly.
The system includes the FCPS5 cartridge, which removes mechanical impurities from the water such as: sand, silt, suspended solids not smaller than 5 µm, FCCST2 which lowers the iron concentration and reduces water hardness, and the FCCBKDF carbon cartridge, which removes chlorine, pesticides, organic substances, lowers the concentration of heavy metals, improves the taste and smell of the water, and also has bacteriostatic properties.
Aquafilter FCPS5 is a sediment (mechanical) cartridge made of polypropylene nonwoven fabric, formed so that the filter density increases toward the core.
It retains all kinds of mechanical impurities such as sand, silt, rust, etc. with a particle size of up to 5 microns.
Filtration with a precision of 5 microns is used in under-sink water filters.
Polypropylene foam cartridges are among the newest generation of filter cartridges.
FCPS series cartridges very effectively remove sand, silt, rust and other deposits found in tap water. They can effectively protect domestic heating systems and household appliances.
They are characterized by very high contaminant absorption, as the nonwoven fabric has the consistency of foam containing open-cell microbubbles inside, making the contact area between water and the filtering media equivalent to a football field (for standard 10-inch cartridges).
Specialized water treatment cartridge - softening and iron-removal.
It is filled with a special fine-grained media that can be used for treating drinking and utility water.
As water flows through the active media, total hardness, iron and hydrogen sulfide are reduced.
Used for treating drinking water (product with PZH approval).
Water softening with an ion-exchange granulate cartridge is the cheapest and simplest solution for protecting a kettle, coffee machine, etc. against white scale buildup.
A carbon cartridge filled with activated carbon from coconut shells and KDF media.
Activated carbon from coconut shells removes chlorine and chlorinated solvents from the water
Removes organic contaminants and some pesticides.
Removes aromatic hydrocarbons and polyaromatic compounds, improving the taste and smell of the water.
Removes phenol and benzene.
Removes iron compounds and hydrogen sulfide
Removes heavy metals (arsenic, cadmium, lead, mercury)
KDF media inhibits the growth of bacterial flora on the filter media, reduces the concentration of heavy metals contained in the water (arsenic, cadmium, lead, mercury) and iron, removes hydrogen sulfide and pesticides.
It has a final filter that prevents the media from escaping outside the cartridge
Brass tap, chrome-plated spout with a ceramic valve. Solid water filter tap, supplied with components allowing it to be mounted to a countertop or a flat sink surface.
It is a conformity mark proving that the product complies with the high standards set out in the Water Supply (Water Fittings) Regulations in England and Wales, as well as equivalent water regulations in Scotland and Northern Ireland, which were enacted in 1999. These regulations define the legal requirements for the design, installation, operation and maintenance of water installations, water fittings and water-using devices, and therefore play an important role in protecting public health, securing water supply and promoting efficient water use in customers' premises throughout the United Kingdom.

Choose a set or individual cartridges. Replacement intervals depend on the cartridge and operating conditions.
The system works in stages. First, the FCPS5 cartridge traps mechanical impurities, then FCCST2 reduces hardness, iron and hydrogen sulfide, and finally FCCBKDF limits chlorine, selected organic compounds, pesticides and heavy metals while improving the taste and smell of the water.
No. FP3-K1 is a classic 3-stage under-sink filtration system. It is not a reverse osmosis filter or reverse osmosis system, so it works differently from membrane-based RO sets.
The set includes three filter cartridges: FCPS5, FCCST2 and FCCBKDF. Each is responsible for a different stage of water treatment, and together they form a complete water filtration system for the kitchen.
Yes. The FCCBKDF cartridge with activated carbon from coconut shells and KDF media reduces chlorine, some organic compounds and other substances affecting organoleptic properties, so the water tastes and smells better.
Yes. The set includes a single, brass, chrome-plated tap with a ceramic valve. It is designed to be mounted in a countertop or on a flat sink surface.
The device dimensions are 40 cm, 35 cm and 14 cm. The compact design makes installation under the sink in a typical kitchen cabinet easier.
In addition to the filter set and cartridges, the package includes: a single tap, housing wrench, complete set of connectors for filter installation, 3 centering discs, hose, Teflon tape and operating instructions.
Yes, because the FCCST2 cartridge reduces the overall hardness of the water. This can help reduce white scale buildup in a kettle, coffee machine and other water-contact appliances.
To maintain performance, the system should be installed according to the instructions and the filter cartridges should be replaced regularly. The replacement interval depends on water quality and usage intensity.
