Reddy air mask

Frequently Asked Questions


What is your filter efficiency?

Bacterial Filtration Efficiency 99.8% (tested by Nelson Laboratories)

Viral Filtration Efficiency 99% (tested by Nelson Laboratories)

How is your mask unique?

Conventional masks use electrostatic-assisted melt-blown nonwoven fabric as its filtration medium. While the fabric is broadly used as air filter media as a result of its high filtration efficiency,  once the fabric comes in contact with humidity or moisture, it loses its ability to hold the static charges well and so the filtration efficiency starts to drop. 

ePTFE membrane masks use high-end industrial grade HEPA material – ePTFE(expanded polytetrafluoroethylene) membrane as the filter medium, a highly porous material made up of over 8 billion 0.2 micron pores stacked closely together. As the membrane does not rely on the electrostatic charges to achieve its high filtration efficiency, its performance level stays brilliant regardless of the environment. 

Achieved through continuous innovation,  research and development at REDDY, the membrane demonstrates high filtration efficiency despite having a thickness of only 500nm, making our masks ultra light, highly breathable and comfortable to wear.

How many times can I wear my mask?

We recommend 5-10 times depending on the level and type of activities and the areas you visit.  In general, count 100 hours.

What test or certificate do you have?
  • Bacterial Filtration Efficiency 99.8% and Viral Filtration Efficiency 99.7% (Tested by Nelson Laboratories)
  • Pass EU Harmonised standard EN14683 Type IIR for CE
  • Pass CNS 15980 and CNS 14755 standards (certified by the renowned Taiwan Textile Research Institute)
  • ISO 9001 Quality Assurance Certified Manufacturer
What does the mask protect me from?

The primary use of REDDY air mask is to protect the wearer from inhaling harmful everyday air pollutants which are known to have detrimental effects on human health, our masks are also effective in lowering the chance of respiratory disease transmissions such as the flu, common cold and the current COVID-19 virus.
