Coldstream FTO+: reliable filtration with a secure protocol

Analysis of Tests of Coldstream FTO+ filters: efficiency and durability

After examining the filter performance sheets Coldstream FTO+, here is a detailed analysis of their filtration capacity and the limits concerning their long -term performance.

1. Analysis protocol and tested volume

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

Recommended volume and duration of use

  • Announced nominal capacity : 1,500 liters per filter, Or 6 months of use, according to the first reached limit.
  • Safety of 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 loss of efficiency due to the wear of materials.
    • This protocol guarantees secure use by limiting prolonged exposure to contaminants accumulated in the filter.

Tests carried out on specific volumes

  • Bacteria (Klebsiella Terrigena, microparticles) → Reduction> 99,9999 % After 1,500 liters.
  • Heavy metals (lead, mercury, arsenic, aluminum, nickel, chrome, 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 → Reduction> 99 % Over 3,000 liters.
  • Particles and microplastics → Reduction 99.9 % announced.

2. Securing the user protocol

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

3. Implications for the reliability of the filter

  • The tests confirm a Excellent reduction in contaminants within the limits of 1,500 liters or 6 months.
  • However, for a complete duration evaluation, it would be interesting to add:
    • A Debit and saturation test To see if the filtration slows down over time.
    • A assessment of the state of the filter after 6 months of real use under different conditions (highly 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 an excellent reduction in contaminants.
There Double limitation (volume or duration) is a reliability guarantee which guarantees effective filtration without risk of prolonged saturation.

🔹 Final opinion: Unlike other brands that announce capacities without long -term tests, Coldstream adopts a more prudent and realistic approach, thus guaranteeing clean and safe water throughout the use of the filter.
