1. Which mask is right for me? Differences between Single-Use Disposable Mask, High Performance Mask, KN95 mask, N95 mask.

Type Single-Use Disposable Mask High Performance Mask KN95 Mask N95 Mask
What is the intended use/purpose? This 3-layer mask forms a barrier between you and the environment. Not intended to provide liquid barrier protection or for prevention of inhalation exposure. Fluid resistant and designed to provide barrier protection against large droplets, splashes or sprays of body or other hazardous fluids.  Protects others from wearer’s respiratory emissions. However, does not have air-tight seal and does not protect its wearer against airborne particles. Reduce wearer’s exposure to particles including small particle aerosols and large droplets (only non-oil aerosols). It reduces the wearer’s exposure to particles including small particle aerosols and large droplets. Reduce wearer’s exposure to particles including small particle aerosols and large droplets (only non-oil aerosols). It reduces the wearer’s exposure to particles including small particle aerosols and large droplets.
Filtration Does NOT provide the wearer with a reliable level of protection from inhaling smaller airborne particles and is not considered respiratory protection. Helps protect others from the wearer’s respiratory emissions. Does NOT provide the wearer with a reliable level of protection from inhaling smaller airborne particles and is not considered respiratory protection. Helps protect others from the wearer’s respiratory emissions. Filters out at least 95% of airborne particles including large and small particles. Filters out at least 95% of airborne particles including large and small particles.

2. What is the difference between an N95 mask and a KN95 mask?

An N95 mask or N95 respirator is a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 classification of air filtration, meaning that it filters at least 95% of airborne particles.  A KN95 mask is manufactured and certified in China and meets the Chinese GB-2626 standard. Based on the comparison table below, it is reasonable to consider China KN95, as “equivalent” to US NIOSH N95.

3. Are our KN95 masks certified?

Our K95 masks are certified and meet the standards under GB2626-2006.  FDA approval is pending.

4. What type of filter is in the masks?

  • Disposable face mask – three layers of soft non-woven polypropylenes
  • Surgical mask – three layers of soft non-woven polypropylenes
  • KN95 mask – three layers of melt-blown non-woven material to block 95% of incoming particulates

5. Do the disposable face masks come in different sizes? No. The dimensions of our masks are the following:

  • Disposable face mask – 6.88in x 3.74in (175mm x 95mm)
  • Surgical mask – 6.88in x 3.74in (175mm x 95mm)
  • KN95 mask – 6.88in x 3.74in (175mm x 95mm)

6. How long can I wear the masks for?

If the wearer is using the mask to protect themselves from other people or environmental factors, the best practice is to wear one mask a day. However, if the wearer is sick and using the mask to protect other people from their illness, then we would suggest disposing of the product immediately after use.

7. Can disposable face masks be sterilized and reused?

No. Disposable face masks are intended for a single use only. After use they should be removed using appropriate techniques (i.e. do no touch the front, remove by pulling the elastic ear straps) and disposed of immediately in a waste bin, followed by proper hand hygiene.
