Foreword. It has recently been patented and presented a novel individual endonasal disposable medical device (temporarily named Smart Nose), consisting in a couple of small cone trunks with an internal helix (the entire tool in soft medical silicone), which "captures" and eliminates airborne particulate matter, in particular of polluting origin (PM) but also of allergic nature. Air clearance from such noxious particles has been assessed, as well as nasal resistances, with different configurations of the device, and consequently the most "equilibrated" geometry has been selected considering the best possible "filtering" efficiency vs the best possible respect of nasal respiratory patency. The "capturing" properties of the device are due to a special biogel stratified on the internal surface of each cone trunk and helix: such biogel captures PM due to its electrostatic properties, fixes it thank to its high viscosity and eliminates it (it's disposable). Aim. This paper presents the results of a survey on the opinion of a sample of citizens about the potential agreement on such individual defense from atmospheric pollutants and other airborne noxious particles. Subjects andmethod.The interwiewed persons were 279 common citizens transiently exposed to urban outdoor pollution, but also persons more "sensible" to pollution and airborne particle-derived problems: 19 citizens suffering from allergic oculorhinitis and bronchial asthma, 50 workers operating in an open urban context or unhealthy environment, plus 52 snorers not belonging to such last two categories. Results. The survey in general has demonstrated high interest of the interviewed persons towards Smart Nose: a positive impression has been referred by 70% common citizens, 84% allergics, 73% "polluted" workers. 46% snorers. About 50% of the potential users are convinced about the utility of the device by the description of its characteriscics, others would prefer to test it in advance. Neither invasivity nor fear of unpleasant nasal sensations are likely to constitute a problem: a proposed costless proof is accepted by >90% of the sample, specially by younger people. Conclusion. Exposure to the inhalation to noxious particulate matter is a sensible problem for the citizens, specially those exposed to PM for professional reasons or allergic to pollens and other airborne allergens; less for subjects suffering from disturbances whose solution is linked to proper curative measures more than to preventive ones (snorers). Hope in possible measures intended to clear inspired air passes also through the expectance of relatively costless individual solutions such as that represented by Smart Nose device.
