NEAFS products heat real tea leaves using an electronic heat-control system in order to prevent burning. Because there is no burning or combustion involved, NEAFS products produce no ash, or smoke. Instead, they use heating systems to generate an aerosol based on Propylene Glycol and Vegetable Glycerin, which can be inhaled by users.
Compared to traditional cigarettes which are heated to around 900℃, which is the level of combustion, NEAFS products are gently heated to around 350℃.
Although smoke-free alternatives are not risk-free, it is well known that harmful chemicals in cigarette smoke comes from burning tobacco. Traditional cigarettes include dozens of harmful and potentially harmful chemicals, while NEAFS products allow for a significant level of reduction of those chemicals.
