The Livinguard technology has been proven to destroy> 99.9% of Harmful Viruses.
“The textiles in these masks can permanently inactivate viruses and thus make using maskers considerably safer.” says Professor Uwe Rösler from the Free University of Berlin. “In addition, even after suffering from the pandemic, these textiles can help to reduce hygienic sources of danger in other areas of life and medicine.
What is the Livinguard Technology and how is it effective against viruses?
Step 1: Capture
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”.
Step 2: Destroy
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.
Step 3: Repeat
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 is the actual science behind the Livinguard 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 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.
How do you know that the Livinguard Technology is effective against Bacteria & Viruses?
We have various ranges of different solutions for different types of substrate materials and use cases. Researchers from the Free University of Berlin at the Institute for Animal Hygiene and Environmental Health have now been able to demonstrate that textiles treated with Livinguard Technology can destroy 99.9% of bacteria and viruses.
The effect of this underlying technology is to capture and destroy bacteria and viruses that come in contact with the Livinguard treated fabric. When tested as per the ISO 18184 protocol, Livinguard Technology demonstrated a >99-9% destruction of bacteria and viruses.
The ISO 18184 protocol is the primary international standard for testing the antiviral properties of a textile. The researchers did not modify the protocol’s specifications of testing within 2 hours of contact (between the fabrics and the viruses) after washing the fabrics 10 times. The protocol requires testing within 2 hours because the speed of performance is critical, but 2 hours are needed to allow for enough inoculated viruses to come in contact with the fabrics. The protocol requires testing after 10 washes to ensure durability of performance and wash out any potential antiviral effect caused by chemical leaching.
In testing by different reputed independent labs for other applications and test protocols, our technology has demonstrated even stronger efficacy against different microorganisms within 5 minutes and after 50 washes. We are not aware of any reliable methods to test for efficacy faster than 5 minutes and have not tested beyond 50 washes. All claims made on any product are based on testing directly applicable to that product.
Is this certified?
There are no applicable certifications for the technology broadly, but please see our face masks page to learn about its certifications.
Does the use of the Livinguard face mask prevent bacteria and viruses?
The textiles treated with Livinguard technology that are incorporated into Livinguard face masks have been scientifically tested to neutralize viruses. Based on its disinfecting effect on viruses, we are confident that the technology will disinfect harmful viruses. This protection is sustained through multiple uses and washes when used as recommended.
However, the use of a Livinguard face mask does not substitute the need for good personal hygiene as recommended by the applicable authorities and cannot prevent infection when not wearing the mask and instances where the virus may enter the respiratory tract through other means such as cross contamination through the concerned person’s hand.
How much more effective is the Livinguard face mask in protecting against bacteria and viruses relative to a normal mask?
A conventional N95 mask filters droplets and particles that may carry bacteria or viruses. The Livinguard mask uses such an industry standard filter as well, but offers additional protection by destroying >99% on each layer enveloping this filter. Further testing is still ongoing, but this implies a >99.99% destruction beyond the standard filtration.
Is the Livinguard Technology useful only for face masks?
We will shortly be launching a range of products equipped with the same permanent self-disinfecting Antiviral Technology used in our face masks. Our technology is already in use in menstrual hygiene products, water filters, and bakery solutions, and in the commercial pilot stage for air conditioning filters. However, please note that our specific solutions vary, so efficacy against coronavirus in these solutions is not guaranteed.
We are in active discussions to license our technology to leading global brands across various consumer products, air purification solutions, healthcare & PPE products, and more.
Are there chemicals in the Livinguard Technology?
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.
How is the Livinguard Mask different from other antiviral masks?
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 7x1017 positive charges to inactivate negatively charged viruses and bacteria.
Who manufactured the masks and what are they made of?
The masks are manufactured in Sri Lanka and Indonesia with 100% proprietary-treated cotton fabric. They are treated with Livinguard antimicrobial technology in Switzerland. Other parts of the mask are made from materials including elastic, silicone and plastic.
What is the shelf life of the mask?
Please refer to the manufacturing date printed on the back of the packaging. The shelf life of the mask is 24 months from that manufacturing date, i.e. if the manufacturing date is March 2021, it is best to use the mask by February 2023. Beyond the shelf life, the antiviral and antibacterial performance of the mask will be reduced.
What happens if I use the mask after the shelf life?
Beyond the shelf life, the antiviral and antibacterial performance of the mask will be reduced. Therefore, it is recommended to use the mask within its shelf life.
How long can I use the mask for?
The reusable mask can be washed up to 30 times, and need only be washed once a week. If worn daily and washed weekly, the mask can replace 210 single used masks.
What happens if I continue to use the mask after 30 washes/equivalent 210 single used masks?
After 30 washes, the masks can continue to be used like ordinary masks even though the antiviral and antibacterial performance will be gradually reduced with each additional wash. Thus, it may be used like ordinary cotton masks, or used in conjunction with other masks including disposable medical grade masks for added protection.
Do ensure that the mask is washed according to the guidelines provided in the mask pack after every use as incorrect washing methods will reduce the effectiveness and durability of the mask.
How should the mask be washed? Can I put it into the washing machine and/or dryer?
Please refer to our Usage & Care guide at the product page or care instructions on the packaging. The mask should not be put into a washing machine or dryer.
How do I dispose the mask properly after 30 washes/equivalent 210 single used masks?
When you do dispose of your mask, please do so thoughtfully by discarding it in the rubbish. Let’s all be environmentally friendly and avoid contributing to our waste by littering.
Which mask size do I choose?
Please measure the length from the bridge on your nose under your eyes until just below the chin. Kindly refer to the face mask size guide in the product page on how to measure.
What is the difference between the PRO Mask and the STREET Mask?
All of our masks are treated with Livinguard technology and have been shown to inactivate 99.9% of bacterias, viruses and many other pathogens. This has been proven by various independent bodies, including a study by the FU Berlin and RWTH Aachen. Livinguard masks protect against the transmission of viruses and bacteria through direct contact (cross-contamination).
In contrast to the Livinguard STREET MASK, which has two layers, the three-layered Livinguard PRO MASK offers additional protection against the transmission of pathogens through aerosols, one of the most common transmission routes for viruses. Inside the Livinguard PRO MASK there is a filter medium which filters >95% of particles and aerosols.
How do I know if it’s a PRO Mask or a STREET Mask?
All product packaging clearly distinguishes between the product PRO MASK or STREET MASK. The product name and other specifications are both on the sticker of the protective film and on the outer packaging. If you no longer have the product packaging, the product label on the inside shows which model it is:
- There are three layers on the label of the PRO MASK, namely “Outer”, “Middle” and “Inner”
- If two layers are specified with “Outer” and “Inner”, it is a STREET MASK
