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 atomizer head. Both have a positive effect on producing large quantities of
vapor. Atomizer 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)
