1. What does the NASK do?

* NASK is researched, designed and manufactured in Hong Kong and aims to provide a high protection of N95 respirator with
a comfort of a surgical mask.
* The NASK Nanofiber Smart Masks provide a wide spectrum of protection. It is capable of trapping viruses, killing bacteria as
well as filtering dangerous PM2.5 particulate contaminants.

2. How does NASK Smart Mask work?

* The NASK Nanofiber Smart Masks utilizes the Patented Nanofiber technology to create an incredibly thin mask.
* A unique formula is used during the creation process which incorporates anti-bacterial technology into the mask.

3. Why use Nanofibers?

* Nanofibers are extremely thin – they are around 200 – 300 times thinner than a human hair
* Nanofibers represent a higher surface area which increases filtration efficiency
* The mask that produced can be very porous offering lower air resistance and is incredibly light

4. How does NASK Smart Mask compare to other masks I see available in Chemists?

* Most masks found at chemists are your average surgical facemask do not protect the wearer
* Surgical masks are only designed to stop droplets and small particles produced when infected people cough or sneeze
* The NASK Nanofiber Smart Masks performs the same role, with the added function of providing a high level of protection to the wearer by trapping viruses and killing bacteria

5. There are other nanofibrous masks on the market – how is NASK any different?

* NASK is the only Mask in the market that can successfuly utilizing patented nanotechnology with the unique bacteria killing function to achieve synergistic effect to protect the users

6. There are other nanofibrous masks that don’t use any antibacterial solution – why shouldn’t I just use those instead of NASK?

* Not all nanofibrous masks can really filter out particles at Most Penetrating Particle Size (MPPS)# MPPS is 0.26 – 0.3 microns articles size; particles smaller or greater than MPPS is easy to be filtered
* If this is the case, the masks might not be able to protect the wearers against viruses and bacteria
* Even if masks that can filter out particles at MPPS, yet without the bacterial killing function there still remains cross infection risk as the trapped bacteria can survive on the mask fibers.

7. Is the NASK NIOSH / CE approved?

* NASK has a N95 filtering facepiece respirator (TC-84A-776) certified by NIOSH, US and is the first NIOSH approved nanofiber N95 mask
* NASK another FFP2 Bactericidal Surgical Respirator is the first CE certified Nanofiber respirator approved by BSI (CE2797) – Category III Respirator (achieved Level FFP2 NR)

8. What is the difference between NIOSH & CE regarding personal protective equipment (PPE) standard / requirements?

* The major difference between NIOSH and CE is that the former is a US system whereas CE is a European system

  • NIOSH is part of the US Centers for Disease Control and Prevention (CDC) and is responsible for the approval of personal protective equipment (PPE) to be used in the workplace
  • CE is the regulatory requirements to be complied under the European Union (EU) before the PPE products are to be marketable in EU markets

* Another difference is that NIOSH will perform only 2 tests : Filtration Efficiency Test on NaCl & Breathability Test (Inhal and Exhal); CE certified respirators will go through more tests in a vigorous way as follow :
– Filtration Efficiency by Sodium Chloride particles > 99%
– Filtration Efficiency by Oily particles > 95%
– Breathing Resistance (Inhalation / Exhalation)
– Practical Performance (Compatibility with skin / Easy in maintaining mask in place)
– Total Inward Leakage (Face Sealing Fit Test)
– Carbon Dioxide Content of Inhalation Air
– Flammability

9. How to differentiate the NASK NIOSH N95 when comparing with the best-fitting 3M N95 – 1870 model in the market?

* N95 is a NIOSH term
– “N” means using sodium chloride (NaCl) as the filtration testing agent during the test
– “95” means the filtration efficiency is over 95% of NaCl particle at MPPS※ particle size (0.26 – 0.3 microns) and, 85 Liters/minute airflow as the filtration testing parameters during the test
※ particles smaller or greater than MPPS are easy to be filtered
* Respirators with NIOSH approval shall be identified with an approval number “TC-84A-XXXX”
* By comparing NASK Nanofiber N95 to the best-fitting 3M N95 (1870) respirators, two major conclusions can be drawn# :
i) the overall fit factor of NASK Nanofiber N95 Mask is higher than that of the “best-fitted respirator” 3M 1870, no matter
whether the fit factors are determined before or after nursing procedures
ii) the usability (i.e. user satisfaction) of NASK N95 mask is significantly higher than that of the “best-fitted respirator”
3M 1870 in all investigated aspects including “heat”, “breathability”, “tightness”, “ease in talking”, “mist over glasses”,
“itchiness”, “difficulty of maintaining the mask in place” and “comfort on ear lobe”

10. Does NASK Nanofiber Smart Masks filter PM 2.5 particles?

* Yes – PM2.5 particles are 2.5 microns in size which are around 10 times larger than the MPPS (0.26 – 0.3 microns) used in all NASK’s filtration efficiency testing parameters

11. What else can NASK Nanofiber Smart Masks filter?

* NASK Nanofiber Smart Masks can filter out very fine matter such as but not limited to dust mite allergen, pollen, mold spores and diesel exhaust.

12. Is NASK Nanofiber Smart Mask comfortable to wear?

* NASK Nanofiber Smart Masks utilizes Patented Nanotechnology to create a light-weight, odorless and breathable face mask
* NASK is essentially no thicker than a regular surgical mask that allows comfortable and effective protection all day.

13. Will I be able to breath easily?

* Yes! NASK Nanofiber Smart Masks’ testing airflow rate is 85L/min
# sleeping requires 6L/min, walking 14-26 L/min and maximum exertion 65-100 L/min

14. Can NASK Nanofiber Smart Mask trap influenza virus Ebola etc.?

* Yes – NASK’s unique trapping function can trap viruses such as but not limited to HIV, HPV, Ebola and influenza (e.g. H1N1)
* Nelson Labs, US test reports proved that :
– >99.9% viral filtration efficiency
– >99% bacteria will be killed on contact in 5 minutes
* NASK Nanofiber Smart Masks are intended to provide a high level of respiratory protection when fitted correctly and not as a replacement for proper health management.

18. How long can the NASK Nanofiber Smart Mask be worn for?

* The mask should always be replaced if
– it becomes soiled / damaged, or
– if there is a noticeable increase in breathing resistance
* Due to NASK’s high specific surface to area ratio and high loading capacity, the Nanofiber Smart Masks can be worn 8 hours continuously under moderate polluted environment
