Why choose the Coldstream CTO MAX cartridge?
The CTO MAX filter is a benchmark in purification. It removes up to:
-
99.9999% of bacteria and cysts (E. coli, Giardia, etc.)
-
99.99% of viruses (rotavirus, etc.)
-
99.9% of heavy metals (lead, mercury, etc.), nitrates, fluorine, chlorine, chloramine
-
99.9% of pesticides, herbicides and pharmaceutical residues
-
99.9% of microplastics and fine particles
Its outer blue ceramic layer contains natural antimicrobial agents and a visible wear indicator technology: when the blue surface fades and the white ceramic reappears, it is time to replace the cartridge.
