NOTES & PRECAUTIONS
Sub-Ohm Vaping (Direct Lung Inhalation)
While puffing, the vapor of an e-cigarette is directly inhaled into the lungs. This puffing
technique is referred to as sub-ohm vaping with direct lung inhalation. To achieve this, there
must be low puffing resistance and a strong air supply to the evaporator head. Both have
a positive effect on producing large quantities of vapor. Evaporator heads that support this
puffing technique in the sub-ohm range (resistance usually < 1 ohm) are often referred to as
DL (direct lung) heads. (other abbreviations include DTL and D2L)
