The FCPS20BB10 foam insert is a mechanical water filter of the BIG BLUE 10″ type with a precision of 1 µm, effectively removing sand, silt, and rust while improving water quality.
FCPS20BB10 WodaRO is a BIG BLUE 10" foam filter cartridge designed for mechanical water filtration in home installations. It works well as a water filter at the pre-filtration stage, supporting water treatment and protecting downstream components of the water filtration system, such as inline filters, a reverse osmosis filter or a reverse osmosis system. The 20 µm rating effectively reduces the presence of sand, silt, rust and other sediments, while the polypropylene construction helps maintain good flow and convenient use.

WodaRO FCPS20BB10 is a high-quality mechanical foam cartridge designed for standard Big Blue 4.5" × 10" housings. Its purpose is to retain solid contaminants present in the water before it reaches further filtration stages or the draw-off points in the home.
This type of filter cartridge is especially useful where the water contains visible mechanical sediment. Thanks to 20 µm filtration, it helps improve water clarity and reduce the passage of particles that may lower the comfort of using the installation.
Effective water filtration – the cartridge precisely captures particles as small as 20 µm, such as sand, silt, rust and other mechanical sediments.
First purification stage – it works well as a pre-filter in inline filters and in central water installations in a house or apartment.
Optimal flow – the perforated structure supports even water flow with minimal pressure drop.
Extended service life – durable polypropylene foam and a well-thought-out design allow the cartridge to operate for up to 6 months.
Better water quality – filtration helps improve the clarity, taste and cleanliness of tap water in the kitchen and bathroom.
The FCPS20BB10 model can serve as a basic mechanical filter in domestic and utility installations. It is suitable wherever initial retention of solid contaminants is needed before further water treatment.
In practice, this cartridge can be used as a protective element for downstream system components, reducing the load on more precise filter media. It is a good choice for inline systems and as support for more advanced solutions such as a reverse osmosis filter, reverse osmosis or any other water filtration system requiring preliminary sediment separation.
The cartridge is designed to remove mechanical contaminants. With a filtration rating of 20 µm, it effectively reduces the presence of typical sediments found in plumbing water.
sand,
silt,
rust,
other sediment and mechanical contaminants.
This action helps maintain the cleanliness of tap water and improves everyday comfort when using the installation.
The cartridge is made of certified polypropylene. This material is widely used in mechanical filtration because of its durability, operational resistance and stable performance under typical use conditions.
The foam structure has been designed to effectively trap sediments while maintaining favorable flow conditions. As a result, the cartridge can operate as the first filtration stage without excessively limiting system performance.
The cartridge is intended for standard Big Blue 10" housings with dimensions of 4.5" × 10". To maintain high filtration efficiency and proper flow, the degree of contamination should be checked regularly and the cartridge should be replaced according to operating conditions. Recommended service life is up to 6 months, depending on water quality and intensity of use.
FCPS20BB10 combines a simple operating principle with practical everyday benefits. It helps retain mechanical contaminants at the beginning of the filtration process, supports the protection of the installation and improves the quality of tap water. This is a suitable solution for people looking for an effective and compatible BIG BLUE 10" cartridge for pre-filtration.
