MTL, DL, or RDL? How to Find Your Perfect Vaping Match
Oct 13,2025 | Bili Vape
These terms are often used to describe the ways of vaping.

What is MTL (Mouth-to-Lung)?
MTL, or Mouth-to-Lung, is a two-step process. You first draw the vapor into your mouth, hold it briefly, and then inhale it into your lungs. This style features a tighter, more restricted airflow that closely mimics the sensation of smoking a traditional cigarette.
-
Who is it for? MTL is the most natural and recommended choice for those transitioning from smoking to vaping. It's familiar, easy to use, and highly effective for satisfying nicotine cravings.
What is a MTL Device?
MTL devices are designed for this specific style. They typically use:
-
High-resistance coils (above 1.0Ω).
-
Lower power settings (lower wattage).
-
Higher-strength nicotine e-liquids (like freebase or nicotine salts) are commonly used with them.
What is DL (Direct-Lung)?
DL, or Direct-Lung, is a one-step process, much like taking a deep breath. You inhale the vapor directly into your lungs without pausing in your mouth. This method produces large, intense clouds of vapor but offers a milder throat hit.
-
Who is it for? DL is preferred by experienced vapers who prioritize cloud production and intense flavor. It is generally not recommended for beginners, especially former smokers.
What is a DL Device?
DL devices are built for power and vapor production. They are characterized by:
-
Low-resistance coils (below 1.0Ω).
-
High power output (high wattage).
-
High-VG e-liquids and lower nicotine strengths are essential to accommodate the large vapor production.
What is RDL (Restricted Direct-Lung)?
Think of RDL as the perfect middle ground. It offers a slightly restricted airflow that sits between the tight draw of MTL and the wide-open feel of DL. It's often called the "best of both worlds," delivering the rich flavor of DL with a satisfying throat hit reminiscent of MTL.
-
Who is it for? Perfect for vapers who find MTL too tight and DL too airy. It's an excellent upgrade for those looking for more flavor and vapor without a full commitment to cloud-chasing.
