What Is The Difference Between Mouth To Lung & Direct To Lung Vaping?

February 17, 2021 4 min read

mouth to lung vaping

When browsing through a vape website, you might come across the terms Mouth to Lung (MTL) and Direct to Lung (DL or DTL). In this post you will find an introduction to what the terms above mean, a guide to choosing the technique that is likely to be right for you and the vape equipment you are using to suit your vaping needs.

What is Mouth to Lung inhale?

Mouth to Lung (MTL) is a type of inhaling. This is done by taking vapour into your mouth, hold it in your mouth and then inhale again into your lungs. This is a close experience to smoking traditional cigarettes.

What is Direct to Lung inhale?

Direct to Lung (DL or DTL) is another type of inhale. This is done by inhaling your vapour directly into your lungs, no holding it into your mouth. It’s like taking a deep but light breath of vapour. This is a close experience to shisha or hookah smoking.

Some coils support both MTL and DTL vaping, because after all, the vaper decides how they want to vape.

What is recommended?

New Vapers:

Most new vapers prefer MTL inhaling as it is the closest experience to a traditional cigarette, has a tighter draw, high nicotine levels and delivers a greater throat hit. DTL vaping van be somewhat intense to start with as they are not used to the experience and it causes most people to cough.

Flavour Production:

Some vapers who have been vaping for years believe that more flavour is produced when they vape using the Mouth to Lung technique. This could be due to the Vegetable Glycerin (VG) & Propylene Glycol (PG) ratio or it could be due to the tighter airflow or because the vapour spends more time in your mouth.

Please make sure that you check that your e-liquid is compatible with the coil you use and also the style of vaping you are looking to achieve.

Cloud & Vapour production:

For those looking to produce a great amount of vapour then DTL vaping would be ideal. This is suitable for people that want to produce big clouds and like a more intense vaping experience.


Best E-liquid for Mouth to Lung vaping?

When vaping in mouth to lung style, most vaper avoid using an e-liquid with a ratio of high VG (Vegetable Glycerin). High PG or 50% PG gives vapers a satisfactory throat hit and also enhanced flavour. Try out Vapox e-liquid, it is 50/50 VG/PG and ideal for mouth to lung.

Best E-liquid for Direct to Lung vaping?

When vaping in direct to lung style, you usually use an e-liquid with a higher VG ratio. This gives the vaper a smother throat-hit and more cloud production. High VG ratios are typically 70VG / 30PG and 80VG / 20VG. A higher VG ratio makes the e-liquid thicker and somewhat sweeter.


Nicotine strengths suited to mouth to lung vaping:

This all depends on the nicotine you use or desire for mouth to lung vaping. If you have recently quit smoking, the higher nicotine levels will be better suited as you will receive the throat hit and nicotine rush you desire. In order to reach mouth to lung vaping to its full potential, you will want to use stronger nicotine levels.

Nicotine strengths suited to direct to lung vaping:

Generally speaking, when vaping direct to lung, vapers use little to no nicotine. This is due to using a more powerful device that produces more vapour than mouth to lung devices. This means that even at low nicotine levels, it will feel like you get more nicotine.

Most vapers use low nicotine strengths such as 0%, 0.15%, 0.3% & 0.6%. People tend to convert from mouth to lung vaping to direct to lung vaping in order to reduce their intake of nicotine.


A coil is one of the most important parts of your vape. Once you heat this up and saturate it with liquid, it will allow vapour to be produced. These come in a variety of resistances to suit vapers wanting a Mouth to Lung experience through to a Direct to Lung Vaper.

Higher resistance coils require less power which produces less vapour.

Lower resistance coils require more power which produces more vapour.

Higher resistance coils are usually suited to mouth to lung vapers. This will typically be a resistance higher than 1.0 Ohm. Lower resistance coils are usually suited to direct to lung vapers. This will typically be a resistance lower than 1.0 Ohm and can go as low as 0.1 Ohm.


We can see that it all falls down to the style of vaping you want to have. If you are a smoker looking to quit vaping, then we recommend starting with a Mouth to Lung device and gradually change to Direct to Lung. This all depends on the coils and device used as coils with lower resistance are for direct to lung vaping but high resistance is for mouth to lung vaping.
