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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.
