Cleaning and Maintenance of Coldstream FTO+ filters

To ensure pure and healthy water at all times, it is essential to regularly maintain your Coldstream FTO+ filters. Proper maintenance ensures optimal performance.

Filter Cleaning

  • If the filtration flow slows down, scrub the surface of the filters with a clean scouring pad under running water to remove accumulated deposits.
  • Never use soap, vinegar, or chemicals for cleaning.
  • Never place the filters in a dishwasher or microwave.

Storage During Absence

  • Absence of a few days (less than 5 days)
    Never drink water that has stagnated in the system for several days.  If you are away for more than 5 days, empty the water from the lower reservoir into a container and re-filter it by pouring it back into the upper reservoir.
  • Extended absence
    Empty both reservoirs before leaving.  Remove the lid to allow the filters to dry completely in open air to prevent mold growth in a closed, humid environment. You can also remove the filters from the reservoir, let them dry in a well-ventilated place, and store them in a paper bag to allow moisture to escape.  
    ⚠️ Even if dry on the surface, the filters may remain moist inside: never store your filters in an airtight container.

    Upon your return, clean the reservoirs of your system with water and dish soap. Reinstall the filters, filter a few liters of water, and discard it before resuming normal use.

Important Precautions

  • Never allow your filters to freeze while damp, as this would damage their internal structure and make them unusable.
  • Do not pour boiling water into the system.
  • Do not use the system with seawater, as the filters do not remove salt.
  • Note: Coldstream FTO+ filters provide a faster flow rate than Black Berkey filters: this is normal and does not compromise filtration quality.
