MTL, RDL, and DL describe three ways of inhaling with an electronic cigarette. MTL offers a tight draw and a two-step inhalation. DL is airier and sends the vapor directly into the lungs. RDL falls between the two: more open than MTL, but more restrictive than classic DL.
MTL: Mouth To Lung, a tight draw
With MTL, the vapor is first held in the mouth and then inhaled, somewhat like with a traditional cigarette. The airflow is generally reduced, the amount of vapor is more moderate, and less power is required.
This style is particularly suitable for compact pods and relatively high-resistance coils. It also tends to consume less e-liquid than a very airy vape.
RDL: Restricted Direct Lung, the compromise
RDL is direct inhalation with partially restricted airflow. The vapor is more abundant than with MTL, while retaining a more concentrated sensation and generally lower consumption than a very open DL vape.
This style has become common on versatile pods that can use cartridges or coils with several resistance values.
DL: Direct Lung, an airy vape
With DL, you inhale the vapor directly into your lungs with the airflow wide open. This style generally uses lower-resistance coils and more power, producing a significant amount of vapor. It also uses e-liquid and battery power more quickly.
MTL, RDL, and DL comparison table
| Criterion | MTL | RDL | DL |
|---|---|---|---|
| Draw | Tight | Semi-airy | Airy |
| Inhalation | Mouth then lungs | Restricted direct | Direct |
| Vapor | Moderate | Intermediate | High |
| Power | Rather low | Intermediate | Rather high |
| E-liquid consumption | Generally low | Intermediate | Higher |
These trends are not absolute rules: the resistance value, airflow, e-liquid, and power greatly affect the result.
Which equipment should you choose based on the draw?
For an MTL or light RDL vape
The XROS range is an example of a versatile pod system. The Vaporesso XROS 6 Kit – 30W 1800mAh 3ml can be paired with the Vaporesso XROS Series 2ml / 3ml Pods – Pack of 4, available with several resistance values. Choosing the pod lets you fine-tune the level of restriction and the vaping experience.
For a versatile RDL vape
The Vaporesso Luxe X3 Kit – 45W 2600mAh is a more powerful and versatile pod. The final experience depends on the pod and the airflow setting selected.
For powerful DL vaping
A sub-ohm kit such as the Geekvape Aegis Legend 5 200W 5.5 ml Kit is a stronger example of the airy, high-powered vaping segment.
Which e-liquid should you choose for MTL, RDL or DL?
The PG/VG ratio should match the coil's wicking capacity. Small MTL coils often work well with thinner, balanced liquids, whereas larger sub-ohm coils are generally designed to handle more viscous liquids. Check your device manual and our guide which coil to use with a 50/50 e-liquid.
What about nicotine strength?
The draw affects the amount of vapor inhaled with each puff. High-powered equipment produces more vapor than a small MTL pod; nicotine strength should therefore be chosen based on your equipment, vaping frequency, and individual needs. Our guide which nicotine strength to choose explains these factors in detail.
How do you choose between MTL, RDL and DL?
- Choose MTL if you are looking for a tight, discreet draw that uses less liquid.
- Choose RDL if you want more vapor without switching to a fully open draw.
- Choose DL if you prefer an airy vape, high power, and substantial vapor production.
MTL, RDL and DL FAQ
Can you use MTL with a low-resistance coil?
The resistance value in ohms alone is not enough to define the draw. Airflow, coil design, and power range also matter. Always refer to the manufacturer's specifications.
Does RDL consume more than MTL?
With comparable equipment, a more open and powerful vape tends to vaporize more liquid. RDL generally falls between MTL and DL.
Which draw is easiest for beginners?
Many users find MTL intuitive when they are looking for a tight draw. However, the best choice is still the one that matches the sensation you want and your equipment.
Vaping is not risk-free. Nicotine is addictive. Vaping products are intended for adults.
