Top Filter WOD20B for deionization cartridges for BIG BLUE 20" and treatment stations HHBB-20B. Effectively reduces the concentration of iron ions, limits rusty deposits, and removes metallic taste and odor from water. Helps protect the installation, fittings, and household appliances, improving bathing comfort and laundry quality.
WOD20B Top Filter BIG BLUE 20" iron removal cartridge is an efficient filter cartridge designed for BIG BLUE 20" inline housings and the HHBB-20B water treatment station. The product supports water treatment in household installations, effectively reducing the concentration of iron ions, limiting rusty deposits, and removing metallic taste and odor. It is a practical water filter for users who want to better protect their installation, fittings, and household appliances while improving everyday comfort of water use at home.

The cartridge from the WOD series has been designed to reduce iron compounds present in utility water. The WOD20B model fits 20-inch BIG BLUE type inline housings and can also operate in the HHBB-20B water treatment station.
The presence of iron in water often causes rusty stains, deposits, and unpleasant sensations during use. Using a suitable iron removal cartridge helps improve the comfort of water use in the bathroom, laundry room, and at water draw-off points throughout the home.
WOD20B is intended for use in BIG BLUE 20" inline housings and in the HHBB-20B water treatment station. Thanks to this, it can be part of a home water filtration system wherever it is important to reduce problems related to elevated iron content.
The cartridge can be a good complement to solutions used in domestic and utility installations. In practice, it fits well into an expanded water filtration system, especially where equipment protection and more convenient everyday water use matter. Unlike solutions such as reverse osmosis, an RO filter, a reverse osmosis filter, or a reverse osmosis system, this cartridge is intended for a specific task, namely reducing iron in utility water.
The cartridge must not be used for water of unknown origin or microbiologically contaminated water.
To extend the service life of the cartridge, a housing with a foam cartridge from the WP series or a string-wound WS cartridge should be installed before the WOD cartridge.
Proper selection of pre-filtration has a real impact on the durability of the cartridge and the stability of its operation. Using suitable mechanical protection before the iron removal cartridge helps limit faster wear of the filtration medium and extends the period of effective operation.
* Service life depends on the degree of water contamination.
It is a solution for people who want to reduce the effects of iron present in water without giving up simple installation in a standard BIG BLUE 20" housing. The cartridge helps improve the utility parameters of water while increasing the protection of the home installation and devices exposed to deposits.
If cleaner utility water, fewer rusty deposits, and better comfort in everyday activities are the priority, WOD20B is a practical element of a water treatment system.
