How does the technology work?

Capture

Substrate materials such as textiles that are treated with Livinguard have ~24 billion charges per square centimetre. 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”.

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.

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 textile is free, the charges they had attached to are free and can continue working in this manner.

Additional Questions You Might Have

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:

  1. Range of methods to bind a range of cationic compounds to textiles and other surfaces.
  2. Portfolio of optimized chemistries to inactivate bacteria and viruses, without using traditional metal based antimicrobial agents like silver, copper, zinc, etc.
  3. 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.

Note that since viruses are technically not “living” organisms outside of a host, they cannot be “destroyed”. They are inactivated and rendered harmless.

Is this tested by any reputed bodies?

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 Federal Institute of Aquatic Research & Technology, Swiss Quality Testing Services, Product Safety Laboratories in New York, 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.

RivenGuard Mask FAQs

How long will it last?

Testing has established the mask will continue to be effective after 30 washes providing the described washing procedure is followed

How often do I need to wash it?

Masks should be washed every 10-12 days

I’ve got a beard can I use a mask?

 

Facial hair is an impediment to any mask protection as it prevents a seal against the face

Is there a choice of colour?

No they are currently available in one colour only

Are they proven to kill Covid 19?

 

All tests prove that the Livinguard process to the fabric used to manufacture the mask has proven to be effective against many known bacteria and viruses.

Where are they made ?

 

 

The masks are manufactured in New Zealand from imported LIVINGUARD® components

What sizes are there ?

 

 

 

One size. They are not recommended for children under 7 or persons with breathing difficulties

Can I buy a bulk order cheaper ?

 

 

 

 

Please go to the email us at info@rivenguard.co.nz

Is it eco-friendly?

 

 

 

 

 

The one RIVENGUARD mask replaces 210 standard disposable masks therefore reducing waste by that amount. Standard N95 masks take a very long time to degrade

What certification does it have?

See all the test result listed on the Technical page
