Water filter cartridges BRITA Maxtra Pro Hard Water Expert — 3+1 pcs, 150 L per cartridge, for pitchers and dispensers

BRITA MAXTRA PRO Hard Water Expert replacement cartridges (3+1 pcs) are designed for treating hard and very hard tap water. Each cartridge provides up to 150 L of filtration and uses a four-stage system — fine mesh, coconut-based activated carbon, ion-exchange granules for improved hardness reduction and metal removal, and a high-efficiency final sieve. Cartridges are compatible with BRITA Aluna, Marella, Style, Elemaris and Flow pitcher collections and the Glass pitcher, and their lid and housing parts contain 50% ISCC PLUS-certified bioplastic.
