It eliminated Staphylococcus aureus (including MRSA), Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Salmonella enteritidis to below the detection limit in less than 1 hour. In some test, complete bacterial killing was observed in less than 1 minute.
The viricidal activity was demonstrated by Virology Research Services. A Biosafety Lab located in The University College of London, United Kingdom. They tested our Silver fabric against Human Coronavirus (NL63)*. They observed a 1,2 log (93,69%) reduction of the virus effectivity immediately upon contact with our silver fabric. (on 1 layer) We use 2 layers of silver fabric in our masks.
Note: Human Coronavirus NL63 Remains Infectious on Common Touch Surface Materials (like glass) for 7 days.
* ASTM (American Society for Testing and Materials) advises NL63 as the best alternative to SARS-CoV-2 (see ASTM: Guidance on SARS-CoV-2 Surrogate Selection

The fungicidal activity of our Silver products against Trychophyton mentagrophytes was demonstrated in the JIS L 1902 test. After less than 3 hours of incubation, no colony forming units were detectable.
Classification according to Medical Devices Directive 93/42/EEC and Medical Devices Regulation (EU) 2017/745
Medical Face Masks are classified according to Rule 1 for non-invasive devices, as devices that either do not touch the patient or contact intact skin only.
Click here for the Declaration of Conformity for one of our masks.
Classification according to the harmonised European standard EN 14683:2019+AC:2019
Medical face masks are classified as Type I and Type II according to bacterial filtration efficiency, whereby Type II is further divided (Type II and IIR) according to whether or not the mask is splash resistant. The 'R' signifies splash resistance.
Type I medical face masks should only be used for patients and other persons to reduce the risk of spread of infections particularly in epidemic or pandemic situations. Type I masks are not intended for use by healthcare professional in an operating room or in other medical settings with similar requirements.

Safety and biocompatibility was proven in a few in vitro studies. (Japan Food research Laboratories)
- No skin sensitization was observed in compliance with ISO 10993-10:2010 (Biological evaluation of medical devices – Part 10: Test for irritation and skin sensitization)
- No skin irritation was observed in compliance with ISO 10993-10:2010 (Biological evaluation of medical devices – Part 10: Test for irritation and skin sensitization)
- No cytotoxicity was observed in compliance with ISO 10993:2009 (Biological evaluation of medical devices – Part 5: Test for in vitro cytotoxicity)
- No risk was observed on the inhalation of silver particles. The level of particles that were inhaled remained far below safety norms.
- No heavy metals are used in the manufacturing process. (Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003)
- No sulphur based chemicals, sulphates, bromine, chlorine gas, organics etc are used in the production process.
- The water after our production process is processed by our own Effluent Treatment Plant and used to water the gardens. Hence, there is no net release of water into streams etc.
- We have permits which allows us to do the effluent treatment process. The water after treatment is tested by independent laboratories every month and also by the Government authorities on a random basis. We are always in compliance with local laws and regulations
- Once our silver comes in wastewater it will not negatively impact the effluent water treatment. Our tests have shown reduction of Biochemical Oxygen Demand (BOD) in wastewater.
- Silver is obtained from vendors who possess valid licenses issued by the Government. This way we know silver procured is from legitimate sources
- Silver, being precious and a very important metal, can be safely recycled back to its native state. This way there is no net loss of resources of such a fantastic metal
- All silvers are not equal. Silver in nano size can potentially cause significant damage to aquatic lives and also on earth. Our silver has certain unique properties whereby they are always safe and work optimally. We have 3rd party testing showing our product is safe on skin, etc.
Various research articles have shown the safety profile of silver.
