WC10-20B Top Filter is a mechanical, reusable pleated filter insert for BIG BLUE 10" housings and HHBB-10B stations. Made of polyester, it effectively captures sand, silt, rust, and other particulates. Filtration accuracy < 20 microns. The insert can be cleaned by rinsing under running water.
WC10-20B Top Filter pleated cartridge BIG BLUE 10" is a reusable mechanical filter cartridge designed for effective removal of solid contaminants from water, such as sand, silt, rust, and other suspended matter. It fits BIG BLUE 10" inline housings and HHBB-10B systems, making it a practical water filter for residential and commercial installations, supporting water treatment and the operation of the entire water filtration system. Thanks to its polyester construction, the cartridge can be cleaned by rinsing under running water and reused.

The WC10-20B Top Filter model is designed to retain mechanical contaminants present in water. The pleated polyester design increases the filtration surface area, and the < 20 micron filtration rating makes it effective at reducing particles such as sand, silt, rust, and various types of suspended matter.
This solution works particularly well wherever preliminary protection of the water system, fittings, household appliances, and subsequent filtration stages is important. The cartridge can be used as part of systems preparing water for further purification, including where a more advanced system is in operation, such as a reverse osmosis filter, osmotic filter, reverse osmosis, or reverse osmosis system.
Cartridges from the WC series are made of polyester and belong to the group of reusable mechanical filters. The material used performs well in filtering solid contaminants, while the pleated form of the cartridge supports efficient operation while maintaining compact dimensions suitable for the BIG BLUE 10" standard.
An advantage of this solution over many standard disposable cartridges is the ability to clean the cartridge and reuse it for water filtration. It is a convenient solution for users who expect practical operation and simple maintenance.
The WC10-20B cartridge is intended for use in:
It can serve as a mechanical filter in residential and commercial installations where protection of fittings, equipment, and subsequent water treatment components against deposits and solid particles present in water is needed.
The cartridge is designed for repeated use. Cleaning consists of rinsing the cartridge under running water. After removing accumulated contaminants, the cartridge can be reused for further filtration.
The service life between rinses is up to 14000 L, although the actual operating time depends on the degree of water contamination. The greater the amount of suspended matter and sediment in the system, the more frequently the cartridge may need to be cleaned.
Important operating information: do not use the cartridge for water of unknown origin or microbiologically contaminated water.
* Depending on water contamination.
In everyday use, not only filtration effectiveness matters, but also ease of maintenance. The WC10-20B cartridge combines both features: it retains typical mechanical contaminants and allows cleaning without the need for immediate replacement after every fouling. As a result, it can be a practical component in installations where efficient and economical water preparation matters.
It is a good choice for users looking for a solution for pre-filtration, especially upstream of more sensitive devices and treatment systems. The mechanical filter cartridge helps reduce the amount of sediment reaching further stages of the installation.
