Tips
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.

The WWB20B insert is made of sintered activated carbon. Sintered carbon has a significantly larger specific surface area and a greater number of chemically active centers, thus providing about 25% greater operational efficiency compared to other carbon inserts.
The insert treats water by eliminating up to 99% of chlorine and chlorine-like solvents, organic contaminants, phenol, benzene, aromatic hydrocarbons, and polycyclic aromatic compounds.
The insert is suitable for cold drinking water and general use.
⚠️ It should not be used for microbiologically contaminated water or water of unknown origin.
