General Information about Puffing Techniques while Vaping
Moderate Vaping (Mouth-to-Lung)
Sub-Ohm Vaping (Direct Lung Inhalation)
When vaping, a distinction is made between two puffing techniques:
The vapor from an e-cigarette is first collected in the oral cavity for the entire duration of the puff and then
inhaled into the lungs. This puffing technique is referred to as moderate, mouth-to-lung vaping and is similar to
smoking. To achieve this, there must be a noticeable resistance when puffing on the e-cigarette. Evaporator heads
that support this puffing technique in the moderate range (resistance usually > 1 ohm) are often referred to as
MTL (mouth to lung) heads. (Other abbreviations include ML and M2L.)
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)
