In vaping, there are two different methods of inhaling vapour, MTL (Mouth To Lung) and DTL (Direct To Lung). Depending on certain variants, including which type of equipment and what wattage you choose, you will achieve either the MTL or DTL method of vaping.
The deciding factor as to the inhale style of a vape product, is predominantly decided by which coil you are using (as well as the number of watts). Generally, if your coil is rated at below 1.0 Ohm, it’s referred to as a sub ohm coil (e.g 0.3 Ohm or 0.15 Ohm). If you’re vaping at above 1.0 Ohm, this is referred to as an MTL coil (e.g 1.2 Ohm or 1.6 Ohm).
Generally, the Mouth To Lung vaping method can be thought of as akin to smoking a cigarette. The process involves drawing vapour into the mouth and then inhaling it into the lungs - a two-step process. This is considered to be more of a beginner’s method of vaping, as it’s generally quite easygoing and comfortable for most vapers to experience. An MTL inhale is usually a main feature of many beginner vaping kits.
Most people find that vaping with the mouth to lung method allows for an increase in flavour and throat hit. It will generally allow your e-liquid and battery capacity to last a little bit longer. This is mainly due to the reduced amount of electrical charge needed to fire a coil of high resistance.
To use the Mouth To Lung method optimally, it’s generally advised to use high PG e-liquids (those that are around 50% PG or higher in concentration). When it comes to nicotine strength, the vast majority of mouth to lung vape kits or tanks are compatible with all nicotine strengths up to 20mg, which is the threshold set by the TPD. Due to its versatility, we recommend all beginners to start out on an MTL kit or tank due to their ease of use, compatibility with all nicotine strengths and their similarity to a cigarette draw.
On the other hand, we have the Direct To Lung method of vaping, achieved mainly by using sub ohm coils and a high-powered vape mod. As you can see in the infographic above, vapour is inhaled directly into the lungs, similar in method to using a shisha pipe, in that it can create a more full-on vaping experience with a large amount of vapour produced.
Most vapers find that vaping with the DTL method will increase vapour production and in using some e-liquids, users will find that certain flavour notes are ‘unlocked’ that aren’t accessible when using the mouth to lung method.
Generally, when it comes to nicotine strength we advise using e-liquids that are no higher than 6mg nicotine, as the increased power and electrical charge will vapourise a higher percentage of nicotine than with an MTL device. Also, it’s recommended to use e-liquids that have a high VG consistency, as high PG e-liquids can create an increased harshness on the throat at such high temperatures.
If you’re new to vaping, we don’t advise starting your vape journey with a DTL device, but if you choose to do so make sure you’re suitably clued up with our guide on sub ohm vaping.
For quick reading, here’s a detailed breakdown of the different styles of vaping.
|MOUTH TO LUNG VAPING|
|Best method for beginners, some veterans prefer it also.|
|Similar to smoking a cigarette.|
|Allows for more flavour and throat hit.|
|Improved battery life, coil and e-liquid longevity (compared with direct to lung).|
|Best used with high PG e-liquids, at least 50% PG.|
|DIRECT TO LUNG VAPING|
|More suited to experienced users.|
|Similar to using a shisha pipe.|
|Allows for increased vapour production.|
|Allows for higher wattages.|
|Reduced battery life, coil and e-liquid longevity (compared with mouth to lung).|
|Best used with e-liquids high in VG (60% VG and higher) and no more than 6mg nicotine content.|
As you can see, both styles of vaping have their strengths as well as their target market, so to speak. Many vapers find they begin their vaping journey with the recommended MTL style kit before making the step up to DTL and sub ohm vaping, once they have grasped a suitable knowledge of vaping as a whole. Either way is respected and admired, with an extensive range of products dedicated to your preferred style.
