NOTE: You will not feel any heat. To deliver Nicotine from the filter, the heating element can heat up the air to over 302 degrees F, yet the end of the filter will still be at normal room temperature.
There is a heat sensation, very slight but it is there. The heat helps release the nano beads and provide a heat sensation. Put your tongue in the heated airflow, you will feel the heat. Now remove the filter from the heater and try the same test. Big difference heat vs no heat.
