Aviation NanoMask - Optimized for Air Crew & First Responders in High Risk Areas

NanoSafe99TM masks are made from world-leading nanofiber materials, which have proven to be superior physical barriers for microorganism pathogens such as bacteria, viruses, mildew, and mold as well as contaminants like allergens and dust. NanoSafe99TM mask filtration efficiency for both bacteria and viruses is 99%. Filtration efficiency for both allergens and dust particles (size P1) is 99%, and in dust particles PM2/5/10 it is 100%.

NanoSafe99TM mask is a high technology nanofiber product, based upon a three-layer mask composed of eco-textile FNAO 1583 based on PP and NanoLayer PVDF polymer and spunbond based on PP. It is developed and patented by a leading innovator in nanofiber material manufacturing in the Czech Republic. The unique advantages of NanoFiber Face Masks are that the nano fiber layers provide (1) an extremely high filtration efficiency and (2) significantly higher breathability of these layered materials which ensures superior comfort when breathing.

The NanoSafe99TM protective mask was tested at both the Occupational Safety Research Institute - ZL Prague, Czech Republic by ČSN EN 149+A1 and at Nelson Laboratories in the USA. It is resistant to temperature changes and is completely safe for all consumers.

Note: Masks are non-returnable


  • Filters dust, allergens, bacteria, viruses, spores, mildew and mold
  • 100% Made in Czech Republic under European Union Regulations
  • USA & EU Laboratory Tested
  • Scientifically Proven Efficacy
  • Patented Design
  • World-Leading Nano Fiber Technology
  • 99% + Efficiency


  • 1. Wash your hands thoroughly (or use hand sanitizer) before applying the mask.
  • 2. Cover your nose and mouth with the mask, pulling the elastic straps over your ears.
  • 3. The lower pleated side of the mask must be pulled underneath the chin. In the area of the bridge of the nose shape the mask with light pressure on the soft metal insert to formfit the mask so it conforms flush to your face. There should be no gap between your face and the mask when the mask is fitted correctly.
  • 4. If you find that the mask is wet, use a new one.
  • 5. Take off the mask by removing the elastic straps from the ears and remove the mask from the side only, then throw it into a secure refuse bin to prevent others from exposure.
  • 6. Do not reuse a used mask, it is for single use only. After removal of the used mask and before applying a new one wash your hands thoroughly or use hand sanitizer.
  • 7. Masks are packaged in packs of five masks. Before each opening a pack it is necessary to wash your hands thoroughly. Then remove a mask and close the package immediately.
  • 8. For European Union customers only: The EU has approved the NanoSafe99™ mask for reuse after disinfection. It may either be disinfected using UVC light or in the following processes:

  • Instructions for Re-Use of the Mask Repeatedly
  • The NanoSafe99™ nanofiber face mask is designed as disposable protective equipment, however, if it is not dirty or wet it can be sterilized and its useful life for multiple uses can be achieved by the methods described below.
  • Recommended number of sterilizations 2x after first use, of course depending on the environment of use in terms of dust and dirt etc. We do not recommend sterilization for dentists due to the formation of aerosols during drilling and other operations - it must be used once.
    • Forms of face mask sterilization:
    • 1. Hot air sterilization: 75°C (167°F) for 20 minutes performed in a normal kitchen oven
    • 2. Germicidal lamp sterilization: for 15 minutes or 2 minutes with the Aveo V2D2 wand
    • 3. Ozone sterilization: for 10 – 15 minutes
    • Under no circumstances shall you do the following to the mask:
    • 1. Do not boil
    • 2. Do not wash
    • 3. Do not iron
    • 4. Do not wash with soap
    • 5. Do not sterilize in the microwave
    • 6. Do not spray disinfectant on it
    • 7. Do not steam

Q: What is different about the NanoSafe99 mask compared to a N95 respirator mask?

Per Manufacturer: The filtering capacity, and hence the level of protection against pollutants and pathogens, depends on the materials used and the engineering design. The NanoSafe99 mask affords you 99% protection. Also it provides better coverage of your face, cheeks and under your chin. The nano fiber material is breathable; you can actually feel it inflate and deflate with your breathing. The nano fiber material is soft and non-irritating.

The N95 respirator mask affords a protective level of 95%, and the FDA states it is not recommended for use by persons with any breathing issues and cardiac patients. The FDA has cleared the N95 respirator mask only for single use, and not for use by children or persons with facial hair. The KN95 mask has the same issues. The N95 mask is stiff and the material can cause skin irritations.

The type of mask material worn is important in mitigating the risk of infection. A study found that in a healthcare setting, the risk of influenza was substantially higher in the cloth mask group than the medical mask group (making surgical face masks and N95 respirator masks the better option), and the N95 mask performed 25 times better than a 3-ply surgical mask. The NanoSafe99™ mask even outperforms the N95 mask.

Q: How comfortable is the NanoSafe99 mask?

Per Manufacturer: The NanoSafe99 mask has been designed to provide more cheek, face and chin coverage while being lightweight, soft and flexible which makes the wearer more apt to not be tugging at it or readjusting it, actions which can lead to viral contact exposure. The soft metal insert in the nosepiece bridge area is easily adjusted to form fit the mask over your nose.

Q: Can the NanoSafe99 mask be disinfected for reuse?

Per Manufacturer: Our European customers can follow European healthcare guidelines that permit the NanoSafe99 mask to be disinfected prior to reuse by placing the mask in an oven set at 179 degrees for 15 minutes. In the United States, the FDA only allows for single use. See instructions for use details.

Q: What about the efficiency of other masks?

Per Manufacturer: Different types of masks give different levels of protection to the user. In general, cloth masks and most disposable masks do not provide sufficient protection. Healthcare professionals, emergency responders and essential workers have been wearing N95 masks because those masks filter out 95% of the viral particulates. Contaminants in the air differ vastly in size. SARS-CoV-2 (Covid-19) has a size ranging from 60 to 140 nm, which is smaller than bacteria, dust, and pollen. Therefore, masks made of materials with larger pore sizes, such as cotton and synthetic fabric, will not be able to effectively filter these viruses or tiny virus-laden droplets, as compared with those made of materials with much smaller pore sizes. For further information about masks, please refer to the FAA's mask and PPE guidance and to Section 3 in this scientific article.
