How does the technology work?
Substrate materials such as textiles that are treated with Livinguard have ~24 billion charges per square centimeter. The positive charge outside layer of mask hooks/ arrests the negatively charged bacteria and viruses.
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 give up and explode. 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.

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.
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 as per the ISO 18184 protocol. 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.
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, TÜV Rheinland, Hohenstein Institute, NSF International, 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.
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.
Wearing face masks bears a significant risk of cross-contamination, even in case of single-use. A study by Chin et al.1 showed that SARS-CoV-2 can still be found on the outer layer of surgical masks after 7 days, at room temperature. Face masks with antimicrobial properties that continuously destroy viruses and bacteria therefore appear critical to reduce the risk of cross-contamination.
Other non Livinguard masks claim to be antiviral and rely on chemicals such as benzalkonium chloride or metal based technologies such as silver, copper or zinc. Known as releasing or “leaching” technologies they are not permanently bound to the textile surface and can therefore rub off on skin, or more worryingly, be inhaled or swallowed. In addition these non durable technologies find their way into ground, sediment and surface water causing harm to the environment and aquatic life. The key “killing” component is a “chemical” force, which has the potential to force bacteria resistance and reduce benefits.
Livinguard Technology is based on polycationic technology using mechanical action to destroy viruses and bacteria and does not use any of the above referenced biocides nor work in a comparable manner. Livinguard Technology is a non-releasing technology (non leaching), which is great news for humans AND the environment, and has been tested for dermal toxicity and skin irritation.
Each square cm of a livinguard mask has about 7.1017 (700,000,000,000,000,000) positive charges to inactivate negatively charged viruses and bacteria.
Yes, there are chemicals involved in the process and our current recipes contain biocides as active substances. However, they are bound to the surface, and will not be released or leach. All chemicals used are compliant with regulations and impose no danger to the user. Livinguard has passed extensive skin safety testing at Product Safety Labs in the USA as per US EPA requirements and at Hohenstein Institute in Germany as per European standards.
No. As mentioned, during the treatment process of Livinguard masks, PHMB is bound to the textile, thus preventing release during use or inhalation.
This is not related to the Livinguard Technology but to the filtration capacity and breathability of the mask, which will be reduced slowly after multiple washes.
Genotoxicity describes the property of chemicals that damage the genetic information (DNA) within a mammal cell causing mutations, which may lead to cancer. In order to cause damage to the DNA the biocide needs to enter the mammal cell. Since the biocides are bound to the fabric it is not possible for them to be released and find their way to make contact with the mammal DNA.
No. Livinguard textiles have a positive electrostatic charge which is different to static electricity. Our treated textile has no net charge, so the electrostatic behavior is similar to other common textiles.
