PurGuard360® Series

Integrated Shower Filter System with an antimicrobial design, providing up to 150 days* of protection.

PurGuard360® Shower System is an innovative solution designed to protect against harmful waterborne pathogens such as Legionella, Nontuberculous Mycobacteria (NTM), E. Coli, Salmonella, and more. This advanced system features a replaceable 0.08 μm membrane filter cartridge housed within the handle, ensuring exceptional filtration performance. When the cartridge reaches the end of its service life, simply unscrew the shower head and replace it with a new filter, maintaining continuous protection.

The PurGuard360® system is equipped with pre-filtration technology that effectively traps particulates while maintaining strong water flow. Its sterilizing-grade hydrophilic capillary membranes ensure long-lasting performance, retaining harmful microorganisms like fungi, protozoa, and bacteria without limiting water volume. Additionally, the filter includes a silver ion antimicrobial additive to reduce the risk of retrograde contamination.

With an ultra-filtration pore size of 0.08 µm, we provide the highest level of protection against waterborne bacteria, fully compliant with U.S. FDA, USP, and EMA standards for sterile filtered water. Our filters are also certified to ASTM F838-2015ae for Legionella reduction, achieving Log 8 (99.999999%) effectiveness, and are CE marked following EU safety and conformity standards, including the EU Drinking Water Directive (2020/2184) and EN-16421.

Designed for compatibility with all standard shower cradles and quick-connect adapters, the PurGuard360® Shower System combines a durable, reusable shower head with a replaceable filter capsule, minimizing waste and lowering long-term costs. While this system enhances safety and hygiene, it should complement—not replace—local water testing and hygiene practices. Enjoy peace of mind with cleaner, safer water every time you shower.

Benefits:

Highest healthcare safety standards with NSF P376 Certification.
Retains microorganisms without volume restriction.
Waste reduction, and cost reduction with high performance.
Complete Anti-Microbial protection is embedded throughout the system.
Integrates with Legionella Water Management Plans.

For use in hospitals, clinics, and other medical facilities, including skilled nursing and long-term care facilities. Ideal for clinical areas with a heightened risk of hospital-acquired infections (HAIs), such as intensive care units (ICU), neonatal care, oncology, burn centers, and transplant units.

* Filter capacity is influenced by local water conditions, the concentration of microparticles (SDI), and pre-filtration. SDI is measured according to ASTM D4189-95 standards. It is recommended to replace the filter cartridge every 150 days for optimal performance.
