    About Coldstream Ceramic Replacement Cartridge
    (for Stainless Steel MAX Countertop and Under Counter Systems)

    Capacity 3,000L

    The MAX ceramic water purifier provides premium protection against water pollutants, waterborne viruses and delivers great tasting water too.
    It is made up of three key components.

    • The carbon inner core protects against chemical contamination.
    • Surrounding this is a unique ceramic outer layer which gives maximum anti-bacterial protection and removal of particles and microplastics.
    • Finally, the blue ceramic outer layer contains antimicrobial properties which help to eradicate waterborne viruses, providing maximum protection against virtually all water pollutants.


    Cleanable Filter
    This ceramic purification cartridge is cleanable. When debris builds up on the outside of the cartridge, the water processing time will slow down. The cartridge should be removed, and the exterior ceramic shell cleaned with a scrubby (no soap!) under cool running water to restore the speed of filtration before being reinserted into the steel housing. Your local water conditions will determine how frequently cleaning is required.

    Unique Replacement Indicator
    Unlike other ceramic filters, the MAX ceramic purifiers have an innovative outer blue layer containing antimicrobial properties which help the purification process. With repeated cleaning, the blue layer is gradually removed until the underlying white ceramic is exposed, indicating the time to replace the cartridge.

    Contaminant Reduction
    The MAX Water Purifier is performance tested to NSF/ANSI standards for high performance protection from chemicals (including chlorine and chloramine), heavy metals, pharmaceuticals, pesticides & herbicides, particles, microplastics, bacteria, and waterborne viruses.

    NOTE   Some of these contaminants may not be present in your water supply.
