WC20-20B Top Filter is a reusable pleated polyester cartridge for BIG BLUE 20" housings and HHBB-20B stations. It effectively traps mechanical impurities: sand, silt, rust, and suspensions. Filtration accuracy < 20 microns. The cartridge can be cleaned by rinsing under running water.
WC20-20B Top Filter pleated cartridge BIG BLUE 20" is a durable, reusable filter cartridge designed for mechanical water filtration in BIG BLUE 20" filter housings and HHBB-20B stations. Made of polyester, it effectively retains sand, silt, rust, and suspended solids, supporting everyday water treatment and the operation of the entire water filtration system. It is a practical water filter for users who expect effective mechanical filtration, the ability to rinse the cartridge, and reuse it without frequent replacement.

Cartridges from the WC series are reusable mechanical filters designed to retain typical solid contaminants present in water. The WC20-20B Top Filter model is made of polyester and works as a barrier for mechanical particles, helping reduce the passage of contaminants further into the installation.
In practice, this means effective removal of contaminants from water such as:
Thanks to its filtration rating of < 20 microns, the cartridge works well as an initial protection element for the water installation and devices cooperating with the treatment system. It can be used wherever it is important to capture mechanical contaminants before further filtration stages.
The WC20-20B model is intended for 20-inch BIG BLUE filter housings. It also fits the HHBB-20B water treatment station. The BIG BLUE 20" format is often chosen for installations where appropriate flow performance and effective mechanical filtration at the system inlet are important.
Such a cartridge can perform an important protective function for subsequent installation components, including solutions such as a reverse osmosis filter, an RO filter, or a more extensive reverse osmosis system, if mechanical contaminants are to be retained earlier, at the pre-filtration stage.
One of the most important advantages of this model is the ability to clean and reuse it. The cartridge is not a disposable component — after becoming dirty, it can be rinsed and used again for water filtration.
Cleaning the cartridge involves rinsing it under running water. This is a convenient solution for those who want to reduce the frequency of cartridge replacement and keep the filtration system in good condition with simple service procedures.
The polyester construction of the cartridge is adapted to retain mechanical particles present in water. As a result, the cartridge helps protect further installation elements against the buildup of deposits and contaminants.
The WC20-20B Top Filter cartridge has been designed for multiple use. To restore its operating efficiency, it should be cleaned by rinsing it under running water. This maintenance method allows the cartridge to be reused for mechanical filtration.
The service life between rinses is up to 24,000 liters, while the actual operating time depends on the degree of water contamination. The more deposits and suspended solids are present in the water, the sooner the cartridge may require cleaning.
Important operating information: the cartridge should not be used for water of unknown origin or microbiologically contaminated water.
This is a solution for users looking for a combination of effective mechanical filtration and convenient day-to-day use. The polyester pleated cartridge for BIG BLUE 20" housings works well as a component protecting the installation against sand, silt, rust, and suspended solids, while also allowing rinsing and reuse.
In practice, this means:

The cartridge is intended for 20-inch BIG BLUE filter housings and for the HHBB-20B water treatment station.
The WC20-20B model retains mechanical contaminants such as sand, silt, rust, and suspended solids present in water.
The filtration rating is below 20 microns, which allows it to effectively reduce the presence of mechanical particles in the water installation.
Yes. It is a reusable cartridge. After becoming dirty, it can be cleaned by rinsing it under running water and used again for filtration.
Cleaning involves rinsing the cartridge under running water. Regular removal of contaminants helps maintain its operating efficiency.
The service life between rinses is up to 24,000 liters. Actual operating time depends on the level of water contamination.
The operating temperature range is from 2 to 42 °C.
No. The cartridge should not be used for water of unknown origin or water that is microbiologically contaminated.
Yes, mechanical filtration is often used as a preliminary stage in water treatment installations. The cartridge can help protect subsequent system components, including solutions such as a reverse osmosis filter or reverse osmosis system, by retaining sand, rust, and other suspended solids earlier.
