Which criteria should be considered first?
Flow rate, lifespan, filtration technologies, system architecture and long-term performance stability: our articles help distinguish meaningful evaluation criteria from oversimplified marketing arguments.
Water filtration & filter efficiency
Water filtration & filter performance
Not all water filters are created equal. Beyond marketing claims, the real performance of a filtration system depends on several scientific criteria: filter design, technologies used, long-term stability and testing protocols.
In this category, we explain how to objectively evaluate the effectiveness of a water filter, based on concrete, measurable and scientifically relevant criteria.
In this category, you will understand:
- how to assess the real effectiveness of a water filter
- which scientific criteria truly matter
- why flow rate, lifespan and testing protocols must be interpreted carefully
How should advertised performances be interpreted?
A performance claim only makes sense when placed in context: contaminant type, testing protocol, test duration and the overall technical coherence of the system being studied.
