WZM20B Top Filter is a softening cartridge for BIG BLUE 20" filter housings and HHBB-20B stations. It contains fine-grained ion exchange resin and is used for treating cold drinking and utility water. It helps reduce scale buildup on heaters and fixtures, decreases equipment failure rates, and allows for the use of fewer detergents.
WZM20B Top Filter is an efficient BIG BLUE 20" softening cartridge, designed for the treatment of cold drinking and utility water. This filter cartridge with fine-grained ion exchange resin helps reduce scale build-up, supports the protection of household appliances, and improves everyday comfort when using the water system. It works well as part of a larger water filtration system and as a practical water filter installed in BIG BLUE 20" inline housings and the HHBB-20B station.

Cartridges from the WZM series effectively purify and soften drinking and utility water. The WZM20B model is filled with fine-grained ion exchange resin, which helps reduce problems associated with hard water and its impact on the system, fittings, and household appliances.
This solution is intended for use in BIG BLUE 20" inline housings and in the HHBB-20B treatment station. Thanks to its popular format, the cartridge can be conveniently used wherever effective water softening and protection of equipment exposed to mineral deposits are important.
In practice, this means more comfortable water use at home and less strain on appliances operating with hard water. The cartridge helps reduce the formation of deposits that can impair heater performance, affect the condition of fittings, and increase equipment operating costs.
WZM20B Top Filter is designed for installation in:
The cartridge can be used in systems prepared for filtration and softening of cold drinking and utility water. It is a good addition to a household water treatment system wherever the goal is to reduce the negative effects of hard water. It can operate as one of the components of an extensive filtration setup, similarly to other solutions from the water filter category, although its function is clearly focused on softening the medium.
Important operating information:
To ensure the cartridge maintains the highest possible operating efficiency, it is worth ensuring proper preparation of the water supplied to the filter. Preliminary mechanical filtration helps reduce the amount of suspended matter and solid contaminants that could shorten the life of the media.
In household installations, several complementary stages of water treatment are often used. The WZM20B can be part of a larger water filtration system, similarly to sets from the reverse osmosis, osmotic filter, reverse osmosis filter, or reverse osmosis system categories, although its task is primarily to soften water in BIG BLUE 20" housings.
The actual service life of the cartridge depends on the degree of water contamination and the operating conditions of the installation. Regular monitoring of filtration performance and timely cartridge replacement help maintain the expected functional parameters.
* Service life depends on water contamination.

The cartridge is designed for 20-inch BIG BLUE inline housings and for the HHBB-20B treatment station.
The WZM20B model is used for the treatment of cold drinking and utility water. It should not be used for water of unknown origin or microbiologically contaminated water.
The cartridge contains fine-grained ion exchange resin whose purpose is to soften water and reduce problems associated with scale build-up in the installation and appliances.
The key benefits include: protection of heating elements in household appliances against scale, reduced appliance failure rate, lower detergent consumption, effective protection of clothes and fabrics against destructive chlorine, and the ability to treat cold drinking and utility water.
Yes. To extend the cartridge service life, it is recommended to install a housing with a foam cartridge from the WP series or a string-wound WS cartridge before it.
The maximum cartridge service life is 3000 liters, although the actual durability depends on the degree of water contamination.
The cartridge has a length of 20" and a diameter of 4½", which makes it suitable for compatible BIG BLUE 20" housings.
The permissible operating temperature ranges from 2 to 42 °C. The cartridge is designed for cold water.
