Can we PROVE what we claim? Is it TESTED by any recognised external body?

Livinguard® Technology has been successfully tested by several reputed international laboratories in Switzerland, Germany, USA, and India. After conducting more than 65,000 experiments and filing more than 100 patents, Livinguard has come up with their unique and powerful coronavirus killing technology that is a global game changer.

Proven to destroy SARS-CoV-2, the virus that causes COVID-19

Researchers from the Free University of Berlin at the Institute for Animal Hygiene and Environmental Health have been able to demonstrate that textiles treated with Livinguard Technology can reduce SARS-CoV-2 particles by more than 99.9% within a few hours. "The textiles in these masks can thus continuously inactivate the exhaled viruses and can make handling these masks even safer overall," says Professor Uwe Rösler. "In addition, such textiles could also help to reduce hygienic issues in other general and medical areas, even beyond COVID-19."

*Livinguard textile has passed tests for “self-disinfecting” textiles according U.S. EPA Protocol and for skin safety according U.S. EPA Health Effects Test Guidelines.

“Self-disinfecting”? Are there not also other products that can claim the same?

The simple answer is, NO! The approval for being able to make this claim about a textile technology has been given to only 1 company in the world, and that is Livinguard®

Generally, disinfection achieves the prevention of multiplying bacteria. However, without destroying them. Also, the process of disinfection is not performed to the same standard all the time. Its efficiency is very much influenced by a number of different factors e.g. prior cleaning, the type and level of microbial contamination, the concentration of exposure time to the germicide (only 10 min in our 5log  Livinguard® mask), temperature and many more. 

Livinguard®’s unique technology of self-disinfection on the other hand, is not compromised by any of these factors. Powerful 5log (99.999% efficacy) reduction within only 10 minutes is a performance achieved, tested and proven only on the Livinguard® invented technology.

This is the reason we can confidently and proudly say, our 5log Face Mask gives you the best available protection against bacteria, viruses and fungi.

5 log reduction in 10 minutes enables EPA approved 
“self-disinfection” claims

Protocol 90072PA4 – 2016: Antimicrobial efficacy

5Log - What does that mean? 

In terms of infection control, ‘Log Reductions’ convey how effective a product is at reducing pathogens. The greater the log reduction the more effective the product is at killing bacteria and other pathogens that can cause infections. 

5log means 99.999% effective!

‘Log’ is short for logarithm, a mathematical term for a power to which a number can be raised. For example, if using 10 as a given number, a Log 3 increase can be shown as 103 or 10 x 10 x 10 = 1,000.

During product efficacy testing, the microbiology laboratories count the number of colony forming units (CFUs) of the given pathogen present at the start of the test. 

The result of the difference between the control and the test product is then expressed as a Log reduction. For example, if the number of CFUs in the control as found to be 1,000,000 (or 106) and the end result using the product was only 1,000 (103), that would be a Log reduction of 3 or a reduction of 99.9%.

Log reductionNumber of CFUs% reductionTimes smaller
0 log (Log0)1 000 0000%N/A
1 log (Log1)100 00090%x 10
2 log (Log2)10 00099%x 100
3 log (Log3)1 00099.9%x 1 000
4 log (Log4)10099.99%x 10 000
5 log (Log5)1099.999%x 100 000

As a basic rule of thumb, for every additional Log reduction number you add a 9 to the percentage reduction, so a log reduction of 3, as illustrated above, is a 99.9% reduction compared with a log reduction of 6 which is equivalent to a 99.9999% reduction.

Is a 5log Face Mask safe for the skin? And also for children?

The Livinguard® technology of our 5log Face Masks has passed extensive skin safety testing at Product Safety Labs in USA per US EPA requirements and at Hohenstein Institute in Germany per European standards. 

Livinguard textile has passed tests for “self-disinfecting” 
textiles according U.S. EPA Protocol and for skin safety 
according U.S. EPA Health Effects Test Guidelines.

  • Only affects “bad” bacteria (transient flora) on the surface of the skin (epidermis).
  • The “good” bacteria (resident flora) reside in deeper skin layers (dermis and hypodermis)
  • Livinguard®’s non-leaching technology does not penetrate the deeper skin layers (dermis and hypodermis).
