WWB20B Top Filter is a block-type carbon cartridge (sintered activated carbon) for BIG BLUE 20" housings. Designed for cold drinking water and general use. Effectively improves the taste, smell, and color of water, reducing organic contaminants and up to 99% of free chlorine and chlorine-like compounds. Lifespan of up to 6 months or 24,000 liters.
WWB20B Top Filter BIG BLUE 20" carbon cartridge is an efficient block-type filter cartridge for Big Blue 20" housings, designed for cold drinking water and general utility water. Sintered activated carbon effectively supports water treatment in domestic and commercial water filtration systems, improving taste, odor, and color while reducing chlorine, organic contaminants, and selected chemical compounds. It is a practical water filter for users who expect high efficiency, high capacity, and compatibility with popular BB 20" housings.

The WWB20B model is a filter cartridge made of sintered activated carbon. This design provides a large specific surface area and a greater number of active chemical centers, resulting in approximately 25% higher service performance compared to other carbon cartridges.
The cartridge is designed to operate with cold drinking water and general utility water. It performs well wherever the goal is to improve the organoleptic properties of water and reduce the presence of selected contaminants affecting everyday comfort of use.
The WWB20B cartridge treats water by reducing a wide range of undesirable substances. Thanks to the use of sintered activated carbon, it helps limit the presence of components that affect the taste, odor, and overall quality of water.
As a result, the cartridge can be a valuable component of advanced utility water treatment installations, as well as a complement to systems that include an additional water filter, reverse osmosis filter, RO filter, or a complete reverse osmosis system.

Important operating note: the cartridge should not be used for microbiologically contaminated water or water of unknown origin. The product is intended for cold water only.
The WWB20B cartridge is designed for Big Blue 20" housings and can operate as part of a cold drinking water or general utility water treatment system. It is a good solution for installations where improving water quality at the pre-filtration or main filtration stage is important.
It can be used as a standalone filter cartridge in a suitable housing or as part of a larger filtration set supporting everyday water treatment at home, in commercial premises, or at a water intake point.
The cartridge performance depends on the quality of the feed water, intensity of use, and the operating conditions of the installation. To maintain high filtration efficiency, the cartridge should be replaced according to its expected service life or earlier if there is a drop in flow performance or deterioration of water parameters.
Regular cartridge replacement helps maintain the expected filtration properties and the full benefits associated with improved taste, odor, and color of water.
The WWB20B cartridge is made of sintered activated carbon. Sintered carbon has a much larger specific surface area as well as a greater number of chemically active centers, and thus approx. 25% higher service performance compared to other carbon cartridges.
The cartridge treats water, removing up to 99% of chlorine and chlorine-like solvents, organic contaminants, phenol, benzene, aromatic hydrocarbons, and polyaromatic compounds.
The cartridge is suitable for cold drinking water and general utility water.
⚠️ It should not be used for microbiologically contaminated water or water of unknown origin.

Yes, the product is intended for cold drinking water and general utility water. It should not be used for microbiologically contaminated water or water of unknown origin.
The cartridge reduces organic contaminants, up to 99% of free chlorine and chlorine-like compounds, phenol, benzene, aromatic hydrocarbons, polyaromatic compounds, and up to 85% of chlorine-derived pesticides.
Yes. One of the main benefits of using the cartridge is the improvement of the taste, odor, and color of water, especially where chlorine or other undesirable notes are noticeable.
The cartridge service life is up to 6 months or up to 24,000 liters of filtered water, depending on water quality and intensity of use.
The maximum capacity is up to 30 liters per minute, which allows the cartridge to be used in installations with higher flow demand.
The operating temperature range is from 2 to 42°C. The product is intended for cold water only.
Sintered activated carbon has a larger specific surface area and more active chemical centers, allowing the cartridge to achieve approximately 25% higher service performance compared to other carbon cartridges.
