Livinguard technology has been shown to deactivate viruses in independent tests conducted at academic laboratories
How does the technology work?
Substrate materials such as textiles that are treated with Livinguard have ~24 billion charges per square centimeter. This is like a magnet for viruses and bacteria. The Livinguard treatment provides a positive “magnet” for the negative viruses and bacteria.
Upon contact, these microbes attach themselves to the textile. This step is called capture or “adsorption”.
The positively charged “magnet” is more powerful than the negative charge of the microbes. The microbes eventually burst. The bacterial and yeast cell walls and the viral protein capsids or envelopes are disrupted, and the now harmless insides leak out and disintegrate.
Once the microbes are destroyed, they have no charge left. They fall off or can be washed off. Once the space they occupied on the material opens up, the charges they attached to are freed. The material continues working with this revolutionary kill power of breadth (variety of germs), efficacy (number of germs), speed, and durability.

What's the actual science behind the technology?
The principle underlying our technologies is the ability of polycationic surfaces to inactivate microorganisms including bacteria, viruses, and several types of fungi, and to do so without leaching.
This principle has been described in scientific literature for two decades, but its understanding and practical applications have been limited. Livinguard has leveraged this principle to invent and patent a paradigm shift from conventional approaches:
Range of methods to bind a range of cationic compounds to textiles and other surfaces
Portfolio of optimized chemistries to inactivate bacteria and viruses, without using traditional metal based antimicrobial agents like silver, copper, zinc, etc.
Methods to combine these with other properties, such as water repellency, hydrophilicity, etc.
According to the the scientific literature, it is probable that the inactivation mechanism of viruses is based on the distortion of the protein capsid by adsorption of negatively charged proteins to the positively charged surface, finally leading to the release of non-infectious RNA.
Tests have shown that after multiple rinses or washes, the treated material (specifically textiles as tested so far) maintains its properties without leaching. This lack of leaching is the underlying reason why the antimicrobial performance is so durable as well as why it is safe for skin contact.
Do we really kill viruses?
Please see the detailed science and technology explanation above.
Livinguard has two primary technology platforms: Livinguard Antiviral Technology and Livinguard Antibacterial Technology. They are differentiated based on the concentration and power of the charges. The Antiviral Technology is more powerful in order to tackle smaller viruses, and is also effective against bacteria.
Livinguard Antiviral Technology has been successfully tested over the course of 5 years across different applications. Testing by the Swiss Federal Institute for NBC Protection and NSF International, among other labs, has shown inactivation of Influenza A Virus, Yellow Fever Virus, Rota Virus, Polio Virus, MS2 phage, and FR coliphage. Antiviral performance is >99.9% on average and even up to >99.9999% in some cases, with unparalleled speed of inactivation, as well as durability of performance.
Testing under the supervision of Dr. Charles Gerba at the Department of Environmental Science at the University of Arizona has recently demonstrated a >99% inactivation rate of HCoV-229E on the textiles used in Livinguard masks. This is widely accepted as being representative of performance against SARS-CoV-2, the virus that causes the COVID-19 infection. Performance is anticipated to be even more powerful, for which further testing is ongoing.
Note that since viruses are technically not “living” organisms outside of a host, they cannot be “killed”. They are inactivated and rendered harmless.
Is this tested by any third party entities
Several facets of our technologies and products have been successfully tested extensively by a variety of international laboratories. These include the Swiss Federal Institute of NBC Protection, TÜV Sud, TUV TÜV Rheinland, Hohenstein Institute, NSF International, Swiss Federal Institute of Aquatic Research & Technology, Swiss Quality Testing Services, Product Safety Laboratories in New York, Department of Environmental Science at the University of Arizona, International Down & Feather Laboratory, and many others. It is currently under application with the US Environmental Protection Agency as the world’s first self-disinfecting textile technology.
Is the technology safe for skin contact and children?
Yes, Livinguard has passed extensive skin safety testing at Product Safety Labs in New York per US EPA standards and at Hohenstein Institute in Germany per European standards.
