MEMBRANE TECHNOLOGY · AHRO® · R&D CENTER · QUALITY ASSURANCE
Advanced Ultrafiltration at 0.08 µm. Physical Barrier. No Chemicals Required.
Ultrafiltration membranes independently certified by IAPMO R&T under ASTM F838-20. 365-day continuous validation. Patent-protected AHRO® technology has been developed over two decades of R&D.
Mentor Water Technologies USA is a manufacturer of advanced Point-of-Use (POU) and Point-of-Entry (POE) water filtration systems. Manufactured in an FDA registered medical device establishment. Independently tested and certified by IAPMO - an ANSI-accredited US laboratory.
HOW IT WORKS — PHYSICAL SIZE EXCLUSION
The membrane acts as a physical barrier. Organisms above 0.08 µm cannot pass.
1
Water enters the 0.08 µm hollow fiber membrane array
Building supply water enters at standard operating pressure. Maintains consistent flow rates with negligible pressure drop under standard operating conditions
2
Membrane physically retains organisms above the pore threshold
Legionella (0.3–0.9 µm), NTM (0.2–0.6 µm), E. coli (0.5–2.0 µm), Pseudomonas (0.5–1.0 µm), Salmonella (0.7–1.5 µm), fungi - all physically blocked. Purely physical filtration. Zero bypass architecture.
3
Effluent Water Quality — Log 10 (99.99999999%) bacterial reduction
Certified by IAPMO R&T under ASTM F838-20. Meets and exceeds CMS and Joint Commission water safety compliance standards.
4
Individual Validation — 100% integrity testing prior to dispatch
Every unit tested for membrane integrity and leak-tightness.
Full traceability. ISO 13485 quality management throughout manufacturing.
Biomaster® antimicrobial housing
Silver-ion technology integrated into medical-grade ABS. This permanent additive inhibits 99.9% of bacterial growth on the filter surface (ISO 22196 tested). Essential for clinical environments to prevent cross-contamination during handling in patient-care areas.
Standard ABS housings in comparable products do not carry this additive. Critical in clinical environments where filters are handled near patient-care areas.
R&D CENTER - INNOVATION PIPELINE
Over two decades of proprietary R&D. Every product in our portfolio is built on exclusive, proprietary technology and protected intellectual property.
Our R&D team drives continuous development across three active program areas:
Active R&D
0.03 µm membrane development
Advanced testing phase. Targeted at hospital-grade sterility requirements where viral nanoparticle retention is a clinical priority.
Active R&D
Extended service life beyond 150 days
Testing program targeting 500–700 day validated service life. Relevant for facilities with limited maintenance access or complex replacement logistics.
Active R&D
Large-scale AHRO® configurations
Next-generation multi-stage systems for hospital campuses, large senior living complexes, and multi-building institutional deployments.
QUALITY CONTROL AND ASSURANCE
From raw material selection to final dispatch, every stage is monitored.
Manufacturing is conducted under an ISO certified quality management system aligned with EN ISO 13485 and ISO 11137-1 for medical device production. Comprehensive reliability testing is performed using international stress testing protocols at every production stage to ensure absolute operational integrity.
100% membrane integrity testing
Every unit undergoes rigorous membrane integrity and leak tightness verification before packaging. We perform individual testing rather than batch sampling to ensure zero defect delivery.
Temperature and Chemical resilience
Proven performance against thermal fluctuations and high chlorine exposure. Our devices maintain structural and filtration integrity throughout the full 150 to 180 day service life under extreme stress protocols.
ISO 13485 Quality System
Medical Grade Manufacturing
Rigorous quality management is applied at every production phase from raw material intake to final dispatch. Our commitment to ISO 13485 standards ensures consistent safety and traceability for every device.
INDEPENDENT TESTING PARTNERS
IAPMO R&T — USA
ANSI-accredited and ISO/IEC 17025 certified laboratory. Provides rigorous third-party certification for NSF P376, ASSE 2011-2022, and ASTM F838-20 standards. All performance results are officially documented and publicly verifiable through the IAPMO listing database.
European Biomedical Institute (EBI)
Conducted comprehensive ISO 10993 biocompatibility testing required for US FDA Class II medical device compliance. This validation ensures all materials are non-toxic and safe for clinical use while maintaining high-level patient protection.
VITENS Laboratory
Conducted a full year continuous testing program under the ASTM F838-20 protocol. Extensive microbiological analysis validated absolute bacterial retention across multiple performance markers to ensure long term safety and effluent reliability.
UMC Göttingen
Independent academic institution. Specializes in water quality monitoring, Legionella prevention, and microbiological analysis. Provides additional validation for certification dossier.
MANUFACTURING COMPLIANCE.
FDA Establishment Registration
Mentor Water Technologies is a registered medical device establishment (Owner/Operator Number 10094411). Our facilities and processes align with stringent federal oversight to manufacture Class II medical devices that meet the highest clinical safety and performance standards for U.S. healthcare institutions.
EPA Facility Registration
We are a U.S. EPA FIFRA registered facility (EPA Est. No. 105402-NLD-1). This registration confirms our adherence to federal standards for antimicrobial material production, ensuring our surface protection technology is manufactured under rigorous public health and safety protocols.
