Coldstream FTO+: Reliable Filtration with a Secure Protocol

Coldstream FTO+ Filter Test Analysis: Effectiveness and Durability

After reviewing the filter performance sheets Coldstream FTO+ used with the filtration system Monderma water filters, here is a detailed analysis of their filtration capacity as well as the limits of their long-term performance.

1. Analysis protocol and volume tested

The tests were carried out by Envirotek Laboratories, under certification NSF/ANSI 42, 53 and P231.

Recommended volume and duration of use

  • Nominal capacity announced : 1,500 liters per filter, Or 6 months of use, depending on the first limit reached.
  • Securing the protocol :
    • If 1,500 liters are reached before 6 months, it is recommended to replace the filter.
    • If the 6 months are reached before 1,500 liters, the filter must also be replaced to avoid any loss of efficiency due to material wear.
    • This protocol guarantees safe use by limiting prolonged exposure to contaminants accumulated in the filter.

Tests performed on specific volumes

  • Bacteria (Klebsiella terrigena, Microparticles) → Discount >99.9999% After 1,500 liters.
  • Heavy metals (Lead, Mercury, Arsenic, Aluminum, Nickel, Chromium, Cadmium, etc.) → Tests up to 3,000 liters, with reduction rates between 81% and >99.9%.
  • Chemical contaminants (Nitrates, Nitrites, Fluorides, Chlorine, Sulfates) → Tested up to 3,000 liters, efficiency between 51% and >99%.
  • Pesticides, Herbicides, Organic Solvents, VOCs, Trihalomethanes → Discount >99% on 3,000 liters.
  • Particles and Microplastics → Discount 99.9% announced.

2. Securing the usage protocol

  • Unlike other systems where longevity is based solely on theoretical estimate, Coldstream FTO+ adopts a double limitation (volume or duration).
  • This approach avoids the risks associated with filter clogging and ensures that efficiency is maintained without exceeding a critical threshold of accumulation of contaminants.
  • Positive point: This protocol limits exposure to the risks of long-term performance impairment.

3. Implications for filter reliability

  • The tests confirm a excellent contaminant reduction within the limits of 1,500 liters or 6 months.
  • However, for a complete evaluation over time, it would be interesting to add:
    • A flow and saturation test to see if filtration slows down over time.
    • A evaluation of the condition of the filter after 6 months of actual use under different conditions (heavily contaminated water, standard water, etc.).

Conclusion

THE Coldstream FTO+ filters offer proven and secure performance up to 1,500 liters or 6 months of use, with excellent contaminant reduction.
There double limitation (volume or duration) is a guarantee of reliability which guarantees effective filtration without risk of prolonged saturation.

🔹 Final opinion: Unlike other brands that advertise capabilities without long-term testing, Coldstream takes a more cautious and realistic approach, ensuring clean and safe water throughout the use of the filter.
