Probably the finest reusable protective mask in the world

Most ordinary masks only filter dirt and dust and fail when it comes to filtering small pathogens like viruses and bacteria. This is where RivenGuard is different and provides you not only with N95 grade filtration but has on-top the patented and certified LIVINGUARD® Technology that actually destroys bacteria and viruses. Meaning the air you are breathing through a RivenGuard mask is as “clean as Swiss air”!

Product description:

The mask is composed of 3-layers. The outer layers are antimicrobial fabrics, as shown below:

Layer 2 (N95) blocks particulate matter


  • N95 filters block most particles in the air and therefore most of the germs contained in the dust


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

Regulatory information:

– Compliant with the ​NIOSH N95 standards​.

– Compliant with Technical textiles

– ​Meditech category​ India, CoEs established under SGDTT for Meditech – SITRA

– Compliant with ​IS 9473​ (Respiratory Protective Devices, Filtering Half Masks to Protect Against Particles).

– Permitted under EN14683 Surgical Mask standard in Europe.

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. If air leaks around the nose, readjust the nose bridge bar as described in step 4. 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.

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 Livinguard 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.
  8. Not recommended for children below the age of 7.
  9. These are not medical grade masks
