MTL vs RDL vs DTL Vaping Explained
When choosing a vape kit or pod system, one of the first decisions you’ll make is how you want to vape. Terms like MTL, RDL, and DTL refer to different vaping styles, each offering a unique draw, vapour output, and overall experience.
If you’re wondering what they all mean - and which one is right for you - this guide breaks it down clearly.
What is MTL Vaping? (Mouth-to-Lung)
MTL (Mouth-to-Lung) vaping closely mimics the feel of smoking a traditional cigarette. You inhale vapour into your mouth first, then draw it into your lungs — ideal for beginners and ex-smokers.
Key Features of MTL Vaping:
- Tight draw, similar to smoking.
- Higher-resistance coils (typically 0.8Ω – 1.2Ω).
- Lower wattage (8W–14W).
- Works best with nicotine salts or 50/50 e-liquids.
- Produces less vapour for a discreet vape.
- Great for vape starter kits and prefilled pod systems.

What is RDL Vaping? (Restricted Direct Lung)
RDL (Restricted Direct-Lung) vaping is the middle ground between MTL and DTL. It allows you to inhale directly into the lungs, but with more resistance than a typical DTL vape.
Key Features of RDL Vaping:
- Semi-open airflow for a smooth, airy draw.
- Coil resistance between 0.4Ω and 0.7Ω.
- Moderate wattage (15W–25W).
- Produces more vapour than MTL, less than DTL.
- Works well with 50/50 or 70/30 e-liquids.
- Balanced flavour and vapour output.

What is DTL Vaping? (Direct-to-Lung)
DTL (Direct-to-Lung) vaping is more advanced and is used by experienced vapers who prefer big clouds and bold flavour. With DTL, you inhale vapour straight into your lungs — similar to taking a deep breath.
Key Features of DTL Vaping:
- Wide-open airflow for minimal resistance.
- Sub-ohm coils (below 0.4Ω).
- Higher wattage (25W and up).
- Produces large, dense clouds.
- Best with high-VG e-liquids (70VG/30PG).
- Ideal for cloud chasers and flavour lovers.

| RDL | Intermediate users | 0.4Ω – 0.7Ω | Medium | 50/50, 70/30 |
| DTL | Advanced vapers | < 0.4Ω | High | 70VG/30PG |
