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).
