Ответ: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 NanoSafe99â?¢ mask even outperforms the N95 mask.

Ответ: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.

Ответ: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.

Ответ: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.
