FCPS foam insert for waterRO BIG BLUE 20" with a precision of 5 microns for mechanical water filtration. Effectively traps sediments and fine solid particles (e.g., silt, sludge), improving the protection of the installation and fittings. Recommended as a pre-filter to protect more expensive carbon, softening, and de-ironing inserts. Made from polypropylene non-woven fabric, it filters through the entire structure of the insert.

Description
FCPS5BB20 WodaRO is a BIG BLUE 20" 5-micron foam cartridge designed for mechanical water filtration in domestic and utility installations. This filter cartridge effectively traps sediments, silt, sludge, and other fine solid particles, helping with water treatment and serving as a very good water filter operating as a pre-stage in a larger water filtration system.
The model is intended for Big Blue 20" housings and can be used in both under-sink filters and inline filters. It protects the water installation, fixtures, and more expensive filter media, including carbon, softening, and iron-removal cartridges. It also works as a protective element before subsequent filtration stages, such as a reverse osmosis filter, an osmosis filter, or a reverse osmosis system.

BIG BLUE 20" foam cartridge for effective mechanical filtration
The cartridge from the FCPS WodaRO BIG BLUE series was designed to remove mechanical contaminants, also referred to as sediment contaminants. A filtration rating of 5 microns means the product effectively captures fine fractions of solid particles present in the water.
This is a practical solution for water from your own well, as well as for municipal water, where sediment may appear during transport in the network. As a result, the cartridge helps limit the passage into the installation of contaminants such as silt, sludge, and similar fine deposits.
How does the FCPS5BB20 WodaRO cartridge work?
The cartridge is made of high-quality foam, i.e. polypropylene nonwoven fabric. The material has been formed in a way that ensures water is filtered through the entire structure of the cartridge, not only on its surface. This solution supports effective retention of mechanical contaminants and promotes stable operation during use.
As a result, the foam cartridge is a good choice wherever reliable pre-filtration is needed before further treatment stages. In practice, it helps protect downstream installation components and more specialized filter cartridges from excessive loading with sediments.
Applications and key benefits
The FCPS5BB20 model is used in under-sink and inline filters. Its role is particularly important as a pre-filter securing subsequent treatment stages.
- removes fine fractions of solid contaminants from the water, such as silt and sludge,
- protects the water installation against mechanical deposits,
- supports the protection of fixtures against contaminants present in the water,
- protects more expensive carbon, softening, and iron-removal cartridges,
- works as a stage preceding a more advanced water filtration system,
- is intended for 20" BIG BLUE housings.
In a properly designed mechanical filtration setup, such a cartridge can improve the operating conditions of subsequent system elements by reducing sediment buildup and extending the usability of more advanced filter media.
The cartridge is intended for 20-inch BIG BLUE housings. Service life depends on the quality of the feed water and the amount of contaminants retained. In the case of high sediment levels, replacement may be needed sooner.
Operation and cartridge selection
A cartridge with a 5-micron rating is suitable wherever the goal is effective capture of fine mechanical contaminants while maintaining good flow. It is a frequent choice for installation protection and as the first stage before further water treatment.
A 4.5" diameter and 20" height mean compatibility with popular BIG BLUE 20" housings. When selecting it, pay attention to the size compatibility of the housing and regularly check the cartridge wear level, especially with well water or water with an elevated amount of sediment.

Questions
What is the FCPS5BB20 WodaRO cartridge used for?
It is a cartridge for mechanical water filtration that retains sediment contaminants, i.e. fine solid particles present in the water, such as silt, sludge, and other deposits.
Which housings does this cartridge fit?
The model is intended for 20" BIG BLUE housings. It has a height of 20" and a diameter of 4.5", so before purchase it is worth checking the size compatibility of the housing.
What is the filtration rating of this cartridge?
The filtration rating is 5 microns. This means effective removal of fine mechanical contaminants from the water.
Is this cartridge suitable for well water?
Yes, the cartridge works well with water from your own well, where mechanical sediments often occur. It can also be used with municipal water, especially when contaminants appear during transport.
Can the cartridge protect other elements of the filtration system?
Yes. It is often used as a pre-filter that protects carbon, softening, and iron-removal cartridges, as well as the water installation and fixtures. It can also support the protection of subsequent stages, such as a reverse osmosis system.
What material is the cartridge made of?
The cartridge is made of polypropylene nonwoven fabric, also referred to as polypropylene foam. The material filters water through the entire structure of the cartridge.
How long can this cartridge be used?
The expected service life is up to 6 months. The actual operating time depends on the quality of the water and the amount of contaminants entering the system.
What is the pressure drop for this cartridge?
The pressure drop is 0.2 - 0.4 bar. This parameter should be taken into account when designing or expanding the filtration system.
Is the cartridge suitable for under-sink and inline filters?
Yes, the cartridge is used in both under-sink and inline filters, provided they are systems compatible with the BIG BLUE 20" format.
