Firewall «Legio Protect™»

Protection of Vulnerable System Components

OxyCat® catalysts combine two important features:

  • As oxidation catalysts they reduce organic contamination even at significantly reduced chemical dosage in water treatment, and they sustainable improve taste and freshness!
  • The unique repellent effects create an insurmountable barrier for microorganisms – Firewall!


The OxyCat firewall protects components such as shower heads or water filters (i.e. RO or water softening systems) from contamination from the system. Reversely, they prevent microorganisms from entering the system at interfaces such as faucets, shower head etc. This offers long-term biofilm prevention inside the system at exposed components.

Legio ProtectTM

Legionella and other thermophiles are a common issue in cold and hot water systems. Interfaces with the environment are critical. The most common example is showering. Legionella  are predominantly airborne. In a household setting, humidifiers and showers/warm water faucets are the main sources of infection. OxyCat® has been used in humidifiers for over 20 years. Pads for shower heads have been tested in a joint project with a leading manufacturer for germ-free shower heads (reports available upon request). The pads have not proven to be very practical. With our new Legio ProtectTM technology we can now offer a more practical solution:

Legio ProtectTM Cartridge:

  • Material: Plastic or stainless-steel cartridge with standard interface.
  • ea of Application: Shower head, water filter, water softening plant, dishwasher, washing machine, warm water
  • Active ingredient: OxyCat® granules

Legio ProtectTM Tube:

  • Material: Plumbing tube, plastic or stainless-steel cartridge, standard interface
  • Area of Application: Connecting tubes or hoses
  • Active ingredient: OxyCat® rope, tube or braided fabric

The image shows the three different possible points of application on a shower head. Generally, one of the three will suffice. The range of the repellent redox potential is remarkable – long-distance effect! For user friendliness we recommend placement directly at the shower head.

OxyCat® has been used in travel filters for over 20 years (German company). That means clean waters even in faraway lands. We are now adding a travel shower head to our product line. The handle contains a combination of OxyCat® and activated charcoal. The adapter allows application worldwide. If you are a manufacturer of water treatment systems, please reach out to us. We will be happy to discuss potential areas of cooperation OxyCat® is compatible will all common disinfection procedures – chlorine, ozone, peroxide, UV and membrane technologies.
