It surface is transparent useful for the facial identification of the wearer without the need to remove it which is an important element during security checks (airports, checkpoints, etc.)
It transparency is an important factor for deaf people who can effortlessly read the lips during the conversation
Another positive aspect of its transparency is that it helps to identify a person with a cold or other ailments that involves a significant emission of personal fluids. The individual with a heavily stained mask inside highlights a high risk of contagion

This product and the material from which it is made, in this case PET material, is not conducive for possible intolerances with the skin. Therefore the mask has successfully passed the biocompatibility test foreseen for this type of products by the harmonized standards EN ISO 10993-10 and EN ISO 10993-5, aimed in particular at checking the possibility of causing irritation and allergies to ensure that it does not cause any damages to the wearer. The following tests were undertaken:
- ISO 10993-5:2009 “Tests for in vitro cytotoxicity” Test no. 4779-20en
- ISO 10993-12: 2012 "Sample preparation and reference materials” Test no. 4779-20en
- UNI EN ISO 10993 10:2013 “Test irritation and skin sensitization” Test no. 20/3988
However, people suffering from any dermatological problems, skin irritation or other skin allergies it is recommended to consult a specialist to establish any incompatibilities

Its conformation favors the non-poliferation of fluids either from the front and from the sides as they are partly closed. The emitter of the circulated but not filtered air, located at the bottom rear of the mask, significantly reduces the possibility of the direct ingress of body fluids from the front. Fresh air is inhaled through two lower rear canals and the warm exhaled air move towards the top of the mask and flows out through the upper rear canal, which due to the forced outflow of carbon dioxide (CO2) enable an easier an smoother breathing.

Cleaning is possible with simple hot water max. 60 degrees or with the addition of detergents suitable for the skin. However, choose products that do not scratch the mask.

Due to the front tank not being pressed on the face, in comparison to ordinary textile masks, it favors gas exchange between fresh air coming from below and exhaled air flowing out from the upper canals. That tank compared to traditional masks gives a feeling of greater accessibility of fresh air.

Due to the decompression process described in the previous section, the air with the carbon dioxide pushed downwards from the fresh air tank is directed to the upper side canals almost entirely eliminating the escape of the steam through the upper part that nearly completely reduces the fogging of glasses even after making dipper exhalation.

Its realization with PET material, which is essentially the same material used to produce the most commonly used plastic bottles for beverages and food containers, makes it deformable, so the mask can be deformed within certain limits without being irreversibly damaged. It can be folded along the axis of the nose and then put it in a bag or a pocket.

It can be wore in a few different ways. Depending on your needs and comfort, it can be used with a single elastic band from both sides which then goes all around the back of the head. Another way of wearnig it is by passing two elastic bands, one for each side, that pass behind the ears, very useful to not mess up the hairstyle. For both ways of wearing it is still possible to choose in which eyes (gaps) to put the bands on. The tension of the mask can be regulated by the two regulating blocks.
