NanoMask FAQ
1. What is filtration efficiency?
Filtration efficiency is the measurement of a filters capacity to remove particulates, such as virus and bacterium, from air as it
flows through the filter. Filtration efficiency is stated as a percentage of efficiency and is affected by such factors as size of the
particulates to be filtered, volume of air and duration of use. An N-95 rated mask, for example, is 95% efficient at removing particles
with a median diameter of approximately 0.3 microns at a volume of 85 liters per minute. Duration of use is a critical factor because
virus and bacterium can infest the filter for extended periods of time. Bacteria can reproduce on their own while virus can survive
for days before infecting a living host. Virus and bacterium can also move through filters over time resulting in an erosion of
filtration efficiency and increase in the associated risk factors.
2. What is the filtration efficiency of the NanoMask?
The filtration efficiency of the filter material used in the NanoMask is 99%. We enhance this intrinsic filtration efficiency with a
coating of nano-particles. The nano-particles counteract the ability of pathogens to live and/or reproduce on the filter by eradicating
virus and bacterium that come into contact with the filter surface.
3. How do the nano-particles work?
Nano-particles act as a destructive agent on the surface of the filter. The particles are positively or negatively charged and
effectively break down the microbial structure of pathogens coming into contact with the filter.
4. How often do you have to replace the filters?
The active life of the nano-particles is approximately 48 continuous hours. We are recommending replacement at that time.
5. What is the shelf life of the filter?
The shelf life is currently two years. We will continue to adjust shelf life as we are able to test aged inventory for efficacy.
6. Have the filters been tested by a reputable testing facility?
Yes, the filters are tested at Nelson Laboratories in Salt Lake City, UT. Nelson Labs has provided high quality test services to
manufacturers in the medical device, pharmaceutical and nutraceutical industries since 1985. They manage a 62,000 sq. ft. FDA
registered facility in Salt Lake City, UT where they maintain 80 labs along with a custom-built 3,000 sq. ft. cleanroom and employ
over 170 scientists and staff. Among their more than 75 degreed scientists are over 25 registered and specialist microbiologists
(National Registry of Microbiologists). They currently offer more than 400 microbiological and analytical tests and are third-party
certified to ISO 9001 (BSI) and EN 45001/IEC/ISO 17025 standards accredited (AMTAC).
7. Has the NanoMask been approved by NIOSH?
The NanoMask is not yet validated by NIOSH. It was important to validate our nano-particle enhanced filter against bacterial and
viral contaminates and NIOSH was not able to provide this biological validation. They currently test against a challenge of sodium
chloride which is not able to measure the effectiveness of the nano-particle enhancement. We are developing the nano-particle
technology in conjunction with the U.S. Military and sodium chloride testing was not sufficient for our purposes. We are registered
with NIOSH and intend to submit the mask for certification in the near future but found it necessary to validate the bacterial and
viral efficacies of the technology prior to a submission to NIOSH. Please refer to the ‘NIOSH Testing” PDF posted in our web site
for a more detailed explanation.
8. Does the NanoMask fit small children?
The NanoMask is currently available only in an adult size. We are developing a children’s size and hope to have it available by
late November.
9. How do you disinfect the NanoMask?
NIOSH recommends the following for cleaning and sanitation:
•  Remove and properly dispose of the filter.
•  Wash the frame in warm (43°C/110°F maximum) water with a mild detergent.
•  Rinse the mask thoroughly in clean, warm (43°C/110°F maximum), preferably running water.
•  If the detergent used does not contain a disinfecting agent immerse the mask for two minutes in a disinfectant water solution    such as:
   • Quaternary ammonia disinfectant (one packet per 2 gallons or per manufacturer's recommendation).
   • Hypochlorite solution (50 ppm of chlorine) made by adding approximately 2 ml of laundry bleach to 1 liter of water at 43°C/110°F.
   • Aqueous solution of iodine (50 ppm of iodine) made by adding approximately 0.8 ml of tincture of iodine (approximately 7%      ammonium and potassium iodide, 45% alcohol, and 48% water) to 1 liter of water at 43°C/110°F.
   • Other commercially available cleansers of equivalent disinfectant quality when used as directed.
• Rinse components thoroughly in clean, warm (43°C/110°F maximum), preferably running water. The importance of thorough
  rinsing cannot be overemphasized. Detergents or disinfectants that dry on the frame may result in dermatitis. In addition, some
  disinfectants may cause deterioration of rubber if not completely removed.
• Allow the respirator to air dry in a non-contaminated environment.
