Many people start vaping to move on from the cough and harshness of smoking. Once the cigarettes stop, it’s natural to focus on finding the right e liquid and kit. One part that often gets missed is the inhale style, because it changes the feel, flavour, throat hit, and vapour output. Online vape shops have plenty of articles and guides to help people transition from smoking to vaping, and understanding inhale styles is one of the most useful places to start.

The three main inhale styles are Mouth to Lung (MTL), Direct to Lung (DTL), and a popular middle option called Restricted Direct to Lung (RDL). Most vape kits are built around one of these styles, which is why it helps to understand the differences before you buy coils, pods, or e liquid for your setup.

Mouth to Lung vs Direct to Lung vs Restricted Direct to Lung

MTL suits people who want a cigarette like draw, with a tighter inhale and smaller vapour. DTL suits people who prefer a more open airflow, larger vapour clouds, and a stronger, fuller inhale into the lungs. RDL sits between the two, with a slightly tighter draw than DTL, but more vapour than MTL.

Many starter kits, pod kits, and vape pens are designed for MTL because it feels familiar for new vapers. Sub ohm kits and larger tanks are usually designed for DTL, with RDL often found in modern refillable pod kits.

What is Mouth to Lung (MTL) Vaping?

Mouth to Lung vaping copies the way most people smoke a cigarette. You draw vapour into your mouth, pause briefly, then inhale into your lungs with a second breath.

Because the vapour rests in the mouth first, many users find flavour is easier to notice, especially with higher PG e liquids. MTL also tends to feel smoother and more controlled, which is why it’s a common choice for anyone switching from smoking.

MTL kits typically use higher resistance coils, usually 1.0 ohm or above, and run at lower wattages. This keeps vapour production modest and battery life longer. The tighter airflow mimics the draw resistance of a cigarette, which helps ex smokers feel at home with the experience.

What is Direct to Lung (DTL) Vaping?

Direct to Lung vaping is a single, steady inhale straight into the lungs, similar to taking a deep breath. The draw is usually more open, and the inhale tends to last longer than an MTL puff.

DTL is often linked with sub ohm vaping, higher power kits, and high VG e liquid. It produces more vapour and can feel more intense, which suits experienced vapers who no longer want a cigarette style draw.

DTL setups typically use coils below 1.0 ohm, often in the 0.2 to 0.5 ohm range, and run at higher wattages. The increased power vaporises more e liquid per puff, which creates the larger clouds associated with this style. Airflow is usually wide open to allow easy, unrestricted inhales.

What is Restricted Direct to Lung (RDL) Vaping?

Restricted Direct to Lung vaping offers a more controlled version of DTL. You still inhale directly to the lungs, but the airflow is tighter and the vapour is not as heavy as full DTL.

RDL became popular with refillable pod kits because it uses less power than typical DTL setups, produces more vapour than MTL, and keeps a satisfying throat hit without feeling too airy.

Many refillable pod kits include 0.4 ohm, 0.6 ohm, or 0.8 ohm pods or coils aimed at RDL use. It is also common to see an airflow slider, which lets you fine tune the draw from loose RDL to a near MTL pull. This makes RDL a practical choice for beginners who want flexibility without committing to one extreme or the other.

How Each Style Changes the Vaping Experience

Your inhale style affects almost everything about the experience. DTL usually feels stronger, with bigger vapour and a heavier inhale. It can be too much at first, especially with the wrong nicotine strength. MTL feels softer and more controlled. It tends to give a clearer flavour at lower vapour levels, with less airflow and a gentler inhale. RDL balances warmth, vapour, and flavour without reaching full cloud levels.

You can also adjust the feel with the right e liquid choice. Higher PG often suits MTL because it carries flavour well and provides a firmer throat hit. Higher VG usually suits DTL because it produces thicker vapour and feels smoother on the inhale.

Nicotine strength also matters. What feels smooth in MTL may feel harsh in DTL because you’re inhaling more vapour per puff. Many DTL vapers drop their nicotine strength to compensate for the increased vapour volume.

Matching E Liquid to Your Inhale Style

The wrong e liquid can make even a good kit feel disappointing. Getting the ratio and strength right for your inhale style makes a noticeable difference.

E Liquid for MTL Vaping

MTL works best with 50/50 VG/PG ratios or higher PG mixes. These thinner liquids wick easily in higher resistance coils and deliver clear flavour with a noticeable throat hit. Nicotine salts are popular for MTL because they feel smooth at higher strengths like 10mg or 20mg.

E Liquid for DTL Vaping

DTL works best with 70/30 or 80/20 VG/PG ratios. These thicker liquids produce denser vapour and suit the lower resistance coils used in sub ohm kits. Freebase nicotine at lower strengths like 3mg or 6mg is typical for DTL because the increased vapour volume means you absorb more nicotine per puff.

E Liquid for RDL Vaping

RDL sits in the middle, so 60/40 or 70/30 VG/PG ratios often work well. Nicotine salts at 10mg or 20mg can work in RDL setups, but some vapers prefer lower strength freebase depending on how open they set the airflow.

MTL Vaping Pros and Cons

Advantages of MTL Vaping

A familiar feel for ex smokers. MTL mirrors the draw and throat hit many people expect, which can make the change from cigarettes easier. The two stage inhale feels natural to anyone who has smoked.

Lower e liquid use. MTL kits usually run at lower wattage and produce less vapour, so e liquid tends to last longer. A 10ml bottle can stretch much further with MTL than DTL.

Cooler vapour. Because power levels are lower, the vape often feels cooler than DTL setups. Some people find this more comfortable, especially for longer sessions.

Strong flavour at lower vapour. Holding vapour in the mouth can make flavour easier to notice, especially with higher PG mixes. Many vapers find MTL delivers more nuanced flavour than DTL.

More discreet in public. Smaller puffs mean smaller clouds, which suits users who want to keep vapour to a minimum. MTL is easier to use without drawing attention.

Works well with higher nicotine options. MTL is a common match for nicotine salts, which are available in higher strengths and can feel smoother at those levels. This helps ex smokers get enough nicotine to manage cravings.

Simple to use. Many refillable MTL pod kits are designed for quick filling, straightforward coil or pod changes, and inhale activation. There’s less to adjust and fewer settings to learn.

Disadvantages of MTL Vaping

Can feel light for cloud focused vapers. Anyone used to DTL vapour volume may find MTL less satisfying at first. The modest clouds can feel underwhelming if you’re chasing visible vapour.

Less suited to very large pulls. Because MTL uses a two stage inhale, it does not suit long, open draws. The technique limits how much vapour you can take in one breath.

May feel basic compared to sub ohm setups. If you are used to high wattage kits, MTL can feel less powerful by comparison. Some vapers find the experience too restrained after trying DTL.

DTL Vaping Pros and Cons

Advantages of DTL Vaping

A stronger inhale and fuller vapour. DTL delivers vapour straight to the lungs in one draw, which many users find more intense and satisfying. The experience feels bigger and more immediate.

Much larger clouds. DTL is the usual choice for high vapour output. If visible clouds are part of the enjoyment for you, DTL delivers.

More open airflow and an easy draw. With one inhale and a more open airflow path, the draw often feels smooth and effortless. There’s no resistance to work against.

Ideal for sub ohm equipment. DTL pairs well with sub ohm tanks, RDAs, and high VG shortfills. It’s the style these kits are designed for.

Disadvantages of DTL Vaping

You may need to lower nicotine strength. DTL can feel harsh with higher nicotine levels, so many users drop nicotine strength compared to MTL. Using 20mg nic salts in a DTL setup would be overwhelming.

Higher e liquid use. More vapour means you will get through e-liquid faster. DTL vapers often go through significantly more liquid per day than MTL vapers.

More risk of a dry or burnt hit if the tank runs low. DTL setups vaporise liquid quickly. If you let the tank or pod run too low, you can scorch the cotton and ruin the coil.

Needs more attention to settings and coil choice. Airflow, wattage, and e liquid ratio matter more, especially for new users. There’s a learning curve to getting the setup right.

RDL Vaping Pros and Cons

Advantages of RDL Vaping

Best of both worlds. RDL gives you more vapour than MTL without the full intensity of DTL. It’s a comfortable middle ground for vapers who want some clouds without going all in.

Works with a wide range of kits. Many modern refillable pod kits are designed with RDL in mind. You get good performance from compact, easy to use hardware.

Adjustable airflow. Most RDL kits include airflow control, which lets you tighten or loosen the draw to suit your preference. One kit can cover multiple styles.

Good throat hit without harshness. The restricted airflow keeps the throat hit satisfying without the intensity that can come with wide open DTL draws.

Disadvantages of RDL Vaping

Neither extreme. If you specifically want the tightest possible draw or the biggest possible clouds, RDL won’t fully satisfy either preference.

Can be confusing for beginners. The middle ground nature of RDL means there’s more room for experimentation, which can feel overwhelming if you’re not sure what you want.

E liquid choice matters more. Getting the right VG/PG balance and nicotine strength for RDL takes some trial and error. What works for one airflow setting may not work for another.

Choosing the Right Vaping Style

Your best option depends on what you want from vaping.

Choose MTL for a tight draw, discreet vapour, and a cigarette like feel. MTL suits ex smokers, people who want simplicity, and anyone who prefers flavour over clouds.

Choose DTL for open airflow, larger clouds, and a stronger inhale. DTL suits experienced vapers who want intensity and don’t mind going through more e liquid.

Choose RDL for a balanced draw with more warmth and vapour than MTL, without the full intensity of DTL. RDL suits vapers who want flexibility and aren’t sure which extreme they prefer.

Trying more than one style can help you find what feels right, especially if you are still early in the switch from smoking. Many kits now offer interchangeable coils or adjustable airflow that lets you experiment without buying multiple setups.

How to Tell What Style Your Kit Supports

If you’re not sure what inhale style your current kit is designed for, check the coil resistance and airflow.

Coils at 1.0 ohm or above usually indicate MTL. These coils run at lower wattages and suit thinner e liquids.

Coils below 0.5 ohm usually indicate DTL. These coils run at higher wattages and need thicker, high VG e liquids.

Coils between 0.5 and 1.0 ohm often indicate RDL. These coils offer a middle ground and work with a range of e liquid ratios.

Airflow also gives clues. A tight, restricted airflow suggests MTL. A wide open airflow suggests DTL. Adjustable airflow that ranges from tight to loose suggests the kit can handle RDL or be adjusted toward either extreme.

Summary

Understanding MTL, DTL, and RDL helps you choose the right kit, coils, and e liquid for the experience you want. MTL suits ex smokers and anyone who wants a tight, controlled draw. DTL suits vapers who want bigger clouds and a more intense inhale. RDL offers a practical middle ground with flexibility built in.

Match your e liquid to your inhale style. Higher PG and nic salts suit MTL. Higher VG and lower strength freebase suit DTL. RDL can work with either depending on your airflow setting.

If you’re switching from smoking, MTL is usually the easiest place to start. Once you’re comfortable, you can experiment with RDL or DTL if you want more vapour and a different feel. The right style is the one that keeps you off cigarettes and feels satisfying to use.
