To ensure  that our masks are highly efficient, we have implemented the newest textile technology to create a triple layer of protection, which makes our masks unique.

Along with other technologies, we ensure our masks fit perfectly and comfortably.

3S mask tested by which organization?

Test report which shows 3S mask pass through full set of KN95 test including inward leakage test is issued by the world top Total Quality Assurance Provider- Intertek

TRIPLE PROTECTION


Outer layer : High density polyester fabric with water, oil, and soil-repellent features by German RUCO-GUARD C6®.

Middle layer : Nano filter-film with filtration efficacy ≥95%, equivalent to KN95.

Inside layer : 100% cotton fabric with anti-bacterial features from Silvadur.

Perfect breathability : 30% more breathable than KN95.

OUTER LAYER

 

RUCO-GUARD C6 is a treatment technology on fabric from German Rudolf Group which offering THE INVISIBLE FIBER PROTECTION SYSTEM.

  • water-repellent (PFOA-, PFOS-free)
  • oil- and soil-repellent
  • breathable
  • preserves colours and fabrics
  • makes textiles dry faster
  • makes fabric care a child's play
  • resistant to washing and dry cleaning
  • weatherproof



MIDDLE LAYER

 

Nano film (3S Mask)

High filtration nano membrane has become a substitution of traditional melt blown cloth acts as a barrier to minute dust and virus. Spider-web structure and multi-layer nano- microporous membrane leads to excellent filtration efficiency ≥95% and the protective effect is more stable and lasting.

 

VS

 

Melt-blown non-woven fabric

While mask made of melt-blown non-woven material mainly rely on electrostatic adsorption to reach filtration efficiency, as the wearing time increases (such as 1 to 2 hours), due to the wearer's breathing and other human activities, the mask becomes damp, its electrostatic adsorption ability weakens, and the filtration efficiency gradually deteriorates.

INSIDE LAYER

 

The polymeric nature, low-dosage profile & formulation of SILVADUR™ make it the choice for antimicrobial finishing treatments.Antimicrobial textiles can cut off the pathways of bacteria to prevent the propagation of germs on textiles, so as to effectively avoid the contact between pathogens and the human body, and reduce the risk of human pathogens and cross-infection rates. SILVADUR™ Advanced Microbial Control Winner of the R&D 100 Award and recognized as one of the top 100 most technologically significant products.

Perfect Breathability

 

3S mask's breathability is 30% higher than KN95 Standard.

What is Inward Leakage Testing for Respirators



In October 2009, the National Institute for Occupational Safety and Health (NIOSH) proposed to add a test for Total Inward Leakage (TIL) to the certification process for half-mask air-purifying particulate respirators. NIOSH believes that adding this component to respirator testing will help ensure that more users will be able to get an adequate fit, and increase the level of protection for users who are not individually fit tested. ISEA believes the proposed rule would not achieve the goal of improving worker protection, would be difficult for employers to implement, and might have the unintended consequence of less workplace fit testing.

3S MASK are the only one cloth mask in the market pass through this inward leakage testing ,thus it is a cloth mask pass through full set test of KN95.
