We are committed to delivering not only high-performance filtration solutions but also unmatched testing integrity.

We go beyond the basic certifications issued by local private compliance organizations by pursuing the highest testing standards and the longest evaluation periods, ensuring our products exceed expectations for safety, durability, and real-world performance.

Our anti-Legionella point-of-use filters underwent a full 12-month independent evaluation by the Netherlands’ leading water authority, Vitens Laboratorium—marking the longest documented testing period for any comparable product.

Simulating real-world conditions, the filters were assessed for daily usage, bacterial load, flow rate, pressure resistance, and post-use disinfection.

Throughout the 12-month trial period, our POU filters consistently achieved 99.999999% (Log 8) bacterial reduction, with proven effectiveness against Legionella pneumophila, Pseudomonas aeruginosa, and NTM, all of which are critical pathogens in healthcare and other high-risk environments. The filters also met stringent hygiene parameters for potable water systems, validating their suitability for continuous use in public buildings, hospitals, and care homes.

The filters maintained full structural and hygienic integrity, confirming their long-term reliability.

No other known product has been tested to this extent, setting a new benchmark for real-world performance, safety, and scientific credibility.

The independent nature of this assessment, combined with its duration and scope, reinforces Mentor’s commitment to offering solutions that go beyond theoretical lab data and deliver proven results in real-world conditions. This validation strengthens confidence among institutional buyers and regulators and clearly positions our filtration systems as a superior alternative to products certified under limited-scope, short-term protocols.
