How does is work

Outer layer -3 Levels of protection*

Unique patented Tripellent Technology on the Outer layer offers 3 levels of protection:

1.LIVINGUARD® Antiviral and repellent coating on the outside of the fabric*
2.LIVINGUARD® Antiviral Technology bonded into the fabric itself
3.LIVINGUARD® Antiviral and repellent coating on the inside of the fabric*
* Tested to destroy >99,9% of SARS-CoV-2

Middle layer- Filters Continuously

Non-woven industry-standard filter channels viruses for destruction to the outer or inner layers.
N95 filters block most particles in the air and therefore most of the germs contained in the dust.

Sandwiched between disinfecting fabrics, it is protected from biological contamination,
allowing the mask to be safely washed and reused. 

Inner layer - Protects Comfortably

Denser than the Outer layer, and also treated with LIVINGUARD® Antiviral Technology,
the fabric provides powerful inactivation of coronavirus.*

Quick-drying with low humidity, the soft and stretchy fabric gives a comfortable fit for the mouth and nose.
This specially treated fabric has 36 billion positive charges/cm2.
*Tested to destroy >99,9% of SARS-CoV-2

Two levels of LIVINGUARD® Technology across the outer and inner layers are each capable of delivering
>99,9% inactivation of SARS-CoV-2.
This is in addition to the middle layer of industry standard filtration.

Swiss Designed Livinguard® Technology

Livinguard-charged layers (1 and 3) destroy microbes

  • Microbes on dust particles filtered by layers 1 and 3 are partially destroyed (in contact with the textile surface)
  • Microbes contained in droplets filtered/absorbed by layer 1 and 3 are destroyed very effectively
  • Microbes accumulating in layer 2 and transferred through respiration to layers 1 and 3 are destroyed upon contact with the textile surface
  • Layers 1 and 3 remain disinfected and show very low contamination levels


  • Strongly reduces the transfer of pathogens from infected persons to the environment and from the environment to non-infected persons
  • As the outside layers (1 and 3) are permanent disinfectants, cross-contamination of the person handling the mask is largely reduced

Filter Efficiency for particles:

The mask fulfils the following requirements, valid up to 30 washes:

N95 passage according to ASTM F2299/F2299M-02 (2010)
Breathability (differential pressure) according to IS 16289:2014 Annex C
Splash resistance according to ASTM F1862/F1862M-13
Bacterial filtration efficiency (BFE) according to ASTM: F2101-14; Test organism Staphylococcus aureus – ATCC 6538
No penetration of blood-borne pathogens as measured using Phi-X174 bacteriophage according to the ISO 16604:2004 method

Fitting instructions and fit check:

Must be followed each time the face mask is worn.
Protection improves by following instructions closely.

  1. Open the pouch and unfold the face mask.
  2. Cup the respirator in your hand to maintain the position on your face.
  3. Adjust the ear loops to fit the face mask comfortably.
  4. Adjust the nose bridge bar tightly around your nose.
  5. To check the respirator-to-face seal, place both hands completely over the respirator and exhale sharply.
  6. If air leaks around the nose, readjust the nose bridge bar as described in step 4. 
  7. The mask should cover the wearer’s mouth, nose, and chin.

      Care instructions:

      1. Store in a clean bag/box, away from sunlight and extreme temperatures
      2. Gently rinse in cold water every 10 to 12 days
      3. Line dry in shade
      4. Do not use detergent or bleach
      5. Do not wring
      6. Do not dry clean
      7. Wash up to 30 times

      Storage and transportation:

      The product should be stored in clean, dry conditions within the temperature range: -20 to +25°C with a maximum relative humidity of 80%.
      Store respirator in the original packaging provided.


      Used products should be disposed of as hazardous waste in accordance with national regulations.

      Mask Certification:

      • Australia: Masks meeting our specifications have been TGA approved as a Class 1 Medical Device.

      • USA: We are working with the FDA to make our mask available in the US during the crisis.

      • EU: permitted under EN14683 Surgical Mask standard in Europe.

      • China: The version of our mask without an exhalation valve has been certified KN95 compliant by Guangdong Testing Institute of Product Quality Supervision.

      • Other regions: Further certifications and conformity are in place for Jordan, Kingdom of Saudi Arabia, UAE, India, and others.

      Cautions and limitations:

      1. This face mask does not eliminate illness, disease or infection and is intended for general public use.
      2. This face mask does not evaluate respirators for use as surgical masks.
      3. This face mask does not supply oxygen. Do not use in atmospheres containing less than 19.5% oxygen.
      4. Do not use the Livingard face mask for chemicals, gases, vapors, oil aerosols, oil based particles or extremely high particulate concentration.
      5. Never substitute, modify, add, or omit parts. Use only exact replacement parts in the configuration as specified by the manufacturer.
      6. Follow fitting instructions carefully, filtering efficiency depends on proper fitting. Use your own mask.
      7. Individuals with a compromised respiratory system, such as asthma or emphysema, should consult a physician and complete a medical evaluation prior to use.
