Aquafilter FCPP20M10B is a polypropylene string filter cartridge for mechanical filtration of cold water. It captures sand, rust, and silt up to 20 microns, making it suitable as a first stage of filtration and protects subsequent cartridges (e.g., carbon, softening, de-ironing). It fits BIG BLUE 10" housings.
FCPP20M10B Aquafilter 20 micron BIG BLUE 10" cartridge is a string-wound filter cartridge made of polypropylene for the mechanical filtration of cold water. It effectively traps sand, rust, and silt down to 20 microns, making it ideal as the first stage of filtration in household installations and as a supporting component in a broader water filtration system. It is a practical water filter cartridge for BIG BLUE 10" housings, helping protect subsequent cartridges, including carbon, softening, and iron-removal cartridges, as well as other water treatment devices.

Aquafilter FCPP20M10B is made of polypropylene string and is intended for mechanical filtration. Its purpose is to capture typical solid contaminants present in cold water, such as sand, rust, and silt.
Thanks to its filtration accuracy of up to 20 microns, the cartridge performs very well at the beginning of a treatment system. This preliminary purification stage helps limit the passage of larger contaminants to the subsequent system components, resulting in better protection and more stable operation.
The FCPP20M10B model is designed for cold water filtration and serves as a sediment cartridge. This means it removes mechanical impurities from water that may affect the durability of subsequent purification stages.
In practice, the cartridge is often used as the first stage where carbon, softening, or iron-removal cartridges are installed further downstream. It can also be a sensible addition to installations with advanced water treatment, an osmotic filter, a reverse osmosis filter, or a complete reverse osmosis system, because preliminary mechanical filtration helps reduce the load on subsequent components.
The cartridge is intended for use in BIG BLUE 10" housings. The 10-inch format and diameter typical of BIG BLUE housings allow it to be used wherever an efficient mechanical cartridge is needed for higher flow rates.
It is a suitable choice for points where effective pre-filtration of cold water is important before further filtration stages.
Important: the cartridge is intended for cold water. To maintain filtration efficiency and properly protect the subsequent installation components, it should be replaced according to its expected service life or earlier if operating conditions and the level of water contamination require it.
The cartridge is designed for standard operation in mechanical filtration systems. Its service life is up to 18 thousand liters or 3-6 months of use, depending on water quality and intensity of use.
Regular cartridge replacement is important not only for filtration efficiency itself, but also for the protection of further treatment stages. In the case of water with a high amount of sediment, replacement may be needed more frequently.

It is a cartridge for the mechanical filtration of cold water. Its purpose is to retain contaminants such as sand, rust, and silt down to 20 microns.
The FCPP20M10B model is intended exclusively for cold water filtration.
The cartridge removes mechanical contaminants, especially sand, rust, and silt, down to 20 microns.
It is most often used as the first filtration stage. This way, it protects subsequent cartridges, for example carbon, softening, or iron-removal cartridges, from excessive sediment load.
The cartridge fits BIG BLUE 10" housings.
The cartridge service life is up to 18 thousand liters or 3-6 months of use. In practice, the replacement frequency depends on the degree of water contamination and the intensity of use.
The cartridge capacity is up to 60 liters per minute, which allows it to be used in installations requiring efficient pre-filtration.
The filtration accuracy is up to 20 microns, which allows effective retention of typical mechanical contaminants present in water.
Yes, mechanical filtration can be a good preliminary stage before solutions such as reverse osmosis or a reverse osmosis filter, because it helps reduce the amount of solid particles reaching subsequent system components.
