General Information regarding Puffing Techniques while Vaping
When vaping, a distinction is made between two puffing techniques:
Moderate Vaping (Mouth-To-Lung)
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 just like smoking a tobacco cigarette. 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.)
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.
