Mouth-to-Lung vs. Direct-to-Lung Vaping: Understanding the Differences

Vaping has evolved into a culture with its own set of styles and techniques, attracting a diverse group of enthusiasts. Among the various aspects of vaping, the method of inhalation plays a significant role in the overall experience. The two primary styles are Mouth-to-Lung (MTL) and Direct-to-Lung (DTL) vaping. Understanding the differences between these two styles is crucial for both beginners and experienced vapers to enhance their vaping experience. This blog aims to demystify MTL and DTL vaping, helping you choose the method that best suits your preferences.

What is Mouth-to-Lung (MTL) Vaping?

Characteristics of MTL Vaping:

  • Similar to Smoking: MTL vaping closely mimics the technique used while smoking cigarettes. The vapour is first drawn into the mouth and then inhaled into the lungs.
  • Tighter Draw: MTL devices typically have a tighter draw, resembling the act of smoking.
  • Flavour Intensity: MTL vaping is known for delivering intense flavour, as the vapour lingers in the mouth before inhalation.
  • Nicotine Delivery: This style is effective for higher nicotine delivery, often preferred by people who have switched from smoking to vaping.

Ideal for:

  • Beginners: New vapers often find MTL vaping more natural and easier to transition from smoking.
  • Flavour Chasers: Those who enjoy savouring the flavour of their e-liquids.
  • Stealth Vapers: MTL vaping generally produces less vapour, making it more discreet.

What is Direct-to-Lung (DTL) Vaping?

Characteristics of DTL Vaping:

  • Deep Inhalation: In DTL vaping, the vapour is inhaled directly into the lungs, similar to taking a deep breath.
  • Airier Draw: Devices designed for DTL vaping typically allow more airflow, resulting in a looser draw.
  • Vapour Production: This style is known for producing large clouds of vapour.
  • Lower Nicotine Concentration: DTL vapers often use e-liquids with lower nicotine levels due to the larger volume of vapour inhaled.

Ideal for:

  • Experienced Vapers: Those who are comfortable with vaping and looking for a more intense experience.
  • Cloud Chasers: Vapers who enjoy producing large clouds of vapour.
  • Lower Nicotine Preference: Ideal for vapers who prefer lower nicotine concentrations but want a more substantial vape.

Key Differences:

  • Technique: MTL involves a two-step process (mouth, then lungs), while DTL is a straight-to-lung method.
  • Device Configuration: MTL devices typically have higher resistance coils and tighter airflow, whereas DTL devices have lower resistance coils and more airflow.
  • E-Liquid Preference: MTL is suited for higher nicotine strengths and PG-heavy e-liquids, while DTL works well with lower nicotine, VG-heavy e-liquids.
  • Vapour Production: MTL produces less vapour, suitable for discreet vaping; DTL produces more vapour, ideal for cloud production.


Choosing between MTL and DTL vaping comes down to personal preference and what you want to achieve with your vaping experience. If you're new to vaping or prefer a style similar to traditional smoking with intense flavours and higher nicotine delivery, MTL might be the way to go. Conversely, if you’re more experienced and enjoy producing large clouds with a smoother throat hit and lower nicotine content, DTL vaping is likely more your style.

Understanding these differences not only enhances your vaping experience but also ensures that you get the most out of your device and e-liquids. Whether you choose MTL or DTL, the key is to enjoy the journey and find what works best for you.
