The Difference Between Mouth to Lung (MTL) & Direct Lung (DL) Vaping


Understanding the differences between mouth to lung (MTL) and direct lung (DL) is crucial if you want to choose the style of vaping that suits you. It will also allow you to understand which settings are best for your style of vaping, as well as how to set up your mod.


What is Mouth to Lung (MTL) Vaping

In today's society, it seems as though everyone is trying to quit smoking. Traditional cigarettes are a burden on our health, to say the least. That’s why electronic cigarettes have taken off so well in recent years. If you want to get away from harmful tobacco use but still want a similar sensation, then it might be time for you to consider vaping too.


Which Device do You Need to MTL Vape?

MTL, which stands for ‘mouth to lung’, is a vape style where you take small puffs and breathe out through your nose. This is considered the easiest way to vape nicotine as it mimics how you would smoke a cigarette. The good news is that MTL is probably the easiest style to adopt.

Restricted Airflow

MTL tanks are designed for a specific type of vaping experience. Instead of providing plenty of airflow like an RDTA, an MTL atomizer requires a high-resistance coil and a high PG (propylene glycol) content e-liquid. What’s more, if you look at most MTL tanks you’ll notice that the airflow holes are really small, sometimes even smaller than 5mm, which means they require a tight draw as opposed to a lung hit.


Smaller Tanks

With MTL vaping the ejuice is consumed in the atomizer and the vapor travels through a small tube directly to your mouth. Therefor, there is little or no vapor escaping from your mouth and very little vaporization. Therefor, these setups are usually limited by how much power they can use, as well as affordability for coils (such as a tight draw).


Smaller Higher Resistance Coils

With a high resistance coil, MTL tanks are much less likely to flood. This is because of the amount of power they are able to put through the coil while still producing dense vapor. They don’t require massive wattage, so you won’t have to worry about burning the cotton and e-liquid up the sides.


Smaller Battery

Trying to find a setup that will give you the best flavor while you’re out and about? Look no further than our MTL device line. These small, pocket-sized vapes are designed specifically to run on lower wattages than most mods. That means they can’t push through high-power coils, but the end result is something that tastes far more natural than a full-power hit.


What Ejuice to Use for MTL Vaping?

Ejuice is generally made from a few things: the type of nicotine, the base or carrier liquid, and flavorings. The first two on the list are the areas you need to consider when it comes to vaporizer use. Because of the devices used, MTL produces a relatively small amount of vapor. If you are looking to satisfy a nicotine craving, you may need a higher-strength juice. You can use regular juice or nicotine salts. Nicotine salt juices cause nicotine to enter the bloodstream faster, and you feel the effects much quicker; depending on your choice of juice, some users may find VG-based ejuices a little too smooth. If you are using a vaping device to replace smoking, you might miss that distinctive ‘throat hit’. In which case, a higher PG-based juice may be better.


What Coil Resistance to Use for MTL Vaping?

Coils for MTL vaping tend to be smaller with higher resistance. Anything around and above 1 ohm is probably better for MTL vaping. Because the coils have high resistance, they heat up quickly even with low power. Remember how we said that MTL devices have tight and restricted airflow? That means there is less air going over the coil. As a result, it is easy to burn coils at high power settings.


What are the Advantages to MTL Vaping?

MTL provides a more intense flavor experience than DL, and many vapers tend to prefer the feeling of MTL vs DL.

  • Easy to get started.

MTL vaping is perfect for people who do not want to go through the expense and effort of learning how to blow clouds. This type of device allows users to get a mouth-to-lung style vape straight out of the box. The flavor here is smooth, there are no coughing fits and the vapor isn’t too warm as your hit will travel right down your throat.

  • The style most similar to smoking

New to vaping? Mouth to lung (MTL) is a style of vaping that is considered to be closer in comparison to smoking. It will feel similar for your mouth, throat and lungs because it's a direct draw on the device, which heats up e-liquid within the tank or cartridge.

  • Better battery life

Great for beginners and experienced vapers alike, MTL vapes let you control and limit the airflow. This makes it easy for you to enjoy thick vapor on a smaller battery device.

  • You use less juice

MTL vaping is a great way to transition from smoking. MTL produces less vapor and generally uses higher-nicotine ejuice. As a result, you'll find that even a small bottle of ejuice lasts longer than with other vape types.

  • Devices tend to be smaller

MTL style devices are generally pretty compact. Pod-style vapes are small enough to fit into a pocket. Because mod and tank MTL style devices use less power, you'll also find that the mod doesn’t need to be huge to accommodate many batteries: with an MTL device, you’re likely to get a smaller overall set up than a DTL device.

  • Less obtrusive in public

MTL(mouth to lung) vaping is a traditional style of vaping in which the vapor travels from the tank/battery, through the coil, then to your mouth before being inhaled. MTL devices produce less vapor. If you are conscious about blowing huge clouds or vaping more inconspicuously, they are ideal.

  • MTL devices are cheaper

MTL devices can be used with any type of tobacco and nicotine. They are available in a wide range of shapes, sizes and designs. You can even purchase one-time-use disposable vapes as well.

Is MTL Right for You?

If you have never vaped before, MTL could be right for you. This entry point into the world of vaping is ideal for ex-smokers looking to quit smoking cigarettes, while also offering mouth to lung sensations that will be familiar to you. With higher concentrations of nicotine in these products, they are ideal for helping anyone trying to kick their cigarette habit once and for all


What is Direct Lung (DL) Vaping?

Direct lung vaping (or DL for short) is traditionally thought of as ‘cloud chasing’. If MTL vaping is sipping through a straw, DL is breathing through a snorkel. It works like this… Remember how we said MTL vaping is a two-stage process? DL vaping is one stage.


What Hardware do You Need to DL Vape?

vapes are different from other e-cigarettes. They are designed to give you the best possible experience by mimicking the look and feel of analog cigarettes. While all MTL vapes use a cartridge system, some vape pods also have threading that allows you to use your own ejuice or prefilled cartridges. You could also buy just a refillable cartridge, allowing you to refill on the go.

Greater Airflow

Direct Lung is one of the most common terms in the vaping community to describe the act of taking puffs directly into your lungs. With this method, you inhale vapor straight into the lungs and then exhale it out. Specifically, direct lung vaping refers to how much airflow there is on the part of a device that goes between your mouth or lips and your lungs.

Lower Resistance and Higher Power

Tank technology has grown steadily since its inception, and continues to evolve as vapers’ demands grow. The first tanks were simple, with a large air tube that allowed ejuice to soak into cotton wicks before dripping into the atomizer body. As more people started using more powerful mods and sub-ohm tanks, high performance coils were introduced, which had lower resistance (less than 1 ohm) and used a large coil design. This helped create bigger clouds of vapor by increasing ejuice drain rates

More Power = Bigger Battery

Sub-ohm vapers need a device that can push enough power through their atomizer to get the coil up to a suitable temperature for thick clouds of vapor. The box mods used by sub-ohm vapers are capable of this, because they have multiple batteries and can do high power outputs for longer periods of time.

Is DL Right for You?

Direct lung vaping is a natural progression from MTL. Most vapers want to really taste the juice and are looking to cut down on their nicotine intake. It can be a little more advanced and take some time to understand what it’s all about. The best way is to learn by doing, and as you will have seen, it doesn’t have to cost a fortune to get a decent setup.



Mouth to Lung versus Direct Lung vaping is an argument that won’t be settled by us, or anyone else for that matter. It's a subjective thing! What we can do is offer you some guidance on the differences so that you can try both styles and make your own mind up.
