How to Adjust Vape Airflow for MTL Vaping: UK Guide (2026)

If you've recently started using a pod vape, you may have noticed an airflow control on the device.

But what does it actually do?

Airflow is an important part of your vaping experience. Changing the amount of air entering your device can alter the draw, vapour production, flavour and overall feel of each puff.

This is particularly important for mouth-to-lung (MTL) vaping, where many users prefer a tighter, more restricted draw.

In this guide, we'll explain what vape airflow is, how it works and how to adjust it for a smoother MTL vaping experience.

What Is Vape Airflow?

Vape airflow refers to the amount of air that enters your vape when you take a puff.

Most devices have airflow openings somewhere around the pod, tank or body of the device.

Depending on the design, you may be able to adjust the airflow using:

• A slider
• A switch
• A rotating ring
• An adjustable opening

Some pod kits have adjustable airflow, while others have a fixed airflow setting.

Why Does Vape Airflow Matter?

Airflow can significantly change how your vape feels and performs.

Adjusting it can affect:

• Draw resistance
• Vapour production
• Vapour temperature
• Flavour
• Throat sensation
• Overall vaping experience

This means the same device can feel quite different depending on how the airflow is configured.

What Is MTL Vaping?

MTL stands for mouth-to-lung.

With MTL vaping, vapour is first drawn into the mouth before being inhaled.

This creates a more restricted style of draw and is commonly associated with lower-powered pod systems.

MTL vaping is particularly popular among people looking for a vaping experience that feels closer to the way a traditional cigarette is smoked.

How to Adjust Vape Airflow

The exact method depends on your device, but the basic principle is simple.

For a tighter draw:

Close the airflow slightly.

This reduces the amount of air entering the device and creates a more restricted draw.

For a looser draw:

Open the airflow further.

This allows more air into the device and produces a more open inhale.

If your device has adjustable airflow, experiment gradually rather than immediately moving it from completely closed to completely open.

What Airflow Is Best for MTL Vaping?

There isn't one perfect airflow setting for everyone.

However, MTL vaping generally works well with a restricted airflow setting.

A tighter airflow can provide:

• A more restricted draw
• A more cigarette-like inhale
• A more concentrated sensation
• Less overall airflow

If the draw feels too tight, open the airflow slightly.

If it feels too loose, close it slightly.

The ideal setting ultimately comes down to your personal preference and the design of your device.

What Happens If the Airflow Is Too Tight?

If your airflow is almost completely closed, the draw may feel excessively restricted.

You may notice:

• Difficulty taking a comfortable puff
• A very tight draw
• Increased heat
• A harsher vaping experience

If the device allows airflow adjustment, opening it slightly may improve the experience.

A very restricted airflow can also affect how much air passes over the coil, so avoid completely closing airflow unless your device specifically allows and recommends doing so.

What Happens If the Airflow Is Too Open?

Opening the airflow too much creates a more airy draw.

You may notice:

• A looser inhale
• More airflow
• Cooler vapour
• Less concentrated flavour
• A less restricted MTL experience

If you prefer a tighter MTL draw, try closing the airflow slightly.

Does Airflow Affect Flavour?

Yes.

Changing airflow can change how flavour is perceived.

A more restricted airflow can produce a more concentrated vaping experience, while opening the airflow allows more air to mix with the vapour.

However, flavour isn't determined by airflow alone.

Other factors include:

• E-liquid
• Coil
• Coil resistance
• Wattage
• PG/VG ratio
• Pod condition
• Device design

Does Airflow Affect Vapour Production?

Airflow can affect the amount and character of vapour you experience.

A more open airflow generally provides a greater volume of air during each puff, which can make the vape feel less dense and more airy.

A more restricted airflow produces a tighter draw.

However, the amount of vapour produced also depends heavily on the coil, wattage and device.

Don't assume that simply opening the airflow will automatically produce significantly more vapour.

Does Airflow Affect Vape Temperature?

Airflow can influence the perceived temperature of vapour.

More airflow can help make the vape feel cooler, while a more restricted airflow can make the vapour feel warmer.

If your vape feels too hot, opening the airflow slightly may help.

You should also check that you're operating the coil within its recommended wattage range.

What Airflow Should You Use With Nicotine Salts?

Nicotine salts are commonly used with lower-powered MTL pod systems.

For this type of vaping, a restricted airflow is often preferred.

However, your exact setting depends on:

• Your device
• Coil resistance
• E-liquid
• Nicotine strength
• Personal preference

If you're using nicotine salts, make sure your device and coil are suitable for the e-liquid you're using.

Does PG/VG Ratio Affect Airflow?

PG/VG ratio and airflow are separate things, but they can both influence the vaping experience.

Many MTL pod systems use 50/50 e-liquid, while higher-VG liquids are generally thicker and commonly associated with higher-powered devices.

If you're using an MTL pod, make sure the e-liquid you're using is suitable for your coil and device.

How Airflow Affects Coil Performance

Your airflow setting works together with the coil and wattage.

If airflow is very restricted while the coil is operating at a relatively high power level, the vapour can feel warmer.

If the airflow is too open for your preferred MTL setup, the vape may feel weak or overly airy.

Finding the right balance between airflow, coil resistance and wattage can make a noticeable difference.

Why Does My Vape Feel Too Tight?

If your vape suddenly feels much tighter than normal, check the airflow opening.

It could have been accidentally moved or partially blocked.

Also check for:

• Dust
• E-liquid residue
• Condensation
• A blocked airflow path
• A poorly fitted pod

If your device has adjustable airflow, try opening it slightly.

If the problem continues, your pod or device may need cleaning.

Why Does My Vape Feel Too Airy?

If your MTL vape feels too airy, the airflow may simply be too open.

Try closing the airflow gradually until you reach a more comfortable draw.

If your device doesn't have adjustable airflow, the draw may be determined by the pod or device design.

In that case, choosing a different pod or device designed for a more restricted MTL draw may be the better solution.

Can Airflow Cause a Vape to Leak?

Airflow itself isn't usually the direct cause of leaking.

However, airflow and the way a pod or coil operates can influence the overall vaping experience.

If your vape is leaking, there are several more likely causes, including:

• Overfilling
• Damaged seals
• A damaged pod
• Condensation
• Incorrect coil installation
• An unsuitable e-liquid

Can Airflow Cause Gurgling?

An incorrect airflow setting isn't necessarily the root cause of gurgling, but changes in airflow can alter how the vape feels when a pod or coil has excess e-liquid.

If your vape is gurgling or bubbling, check the pod and coil rather than simply changing the airflow.

For more information read our guide on why your vape is gurgling and how to fix it.

Best Airflow Setting for Beginners

If you're new to MTL vaping, start with a moderately restricted airflow.

Take a few puffs and see how it feels.

If it's too tight, open the airflow slightly.

If it's too airy, close it slightly.

There's no need to constantly adjust it once you've found a setting that feels comfortable.

Airflow Settings: Quick Guide

Airflow	Typical Experience
Mostly closed	Very restricted, warmer and tighter draw
Slightly open	Tight MTL draw
Half open	More balanced draw
Mostly open	Airier and looser draw
Fully open	Very open draw, depending on device

These descriptions are general because airflow systems vary between devices.

Airflow and Coil Resistance

Coil resistance is another important part of how your vape feels.

Higher-resistance coils are commonly associated with lower-powered MTL vaping.

Lower-resistance coils are generally designed for higher power and can produce more vapour.

Your airflow should therefore be considered alongside your coil resistance and recommended wattage.

Frequently Asked Questions

Should MTL airflow be open or closed?

MTL vaping generally works well with a restricted airflow setting. Start with a partially closed airflow and adjust it until you find a comfortable draw.

Does closing airflow make a vape stronger?

Closing the airflow can make the draw feel more concentrated and may produce a warmer vaping experience, but it doesn't increase the nicotine strength of the e-liquid.

Does opening airflow make a vape cooler?

More airflow can make the vapour feel cooler and create a more open draw.

What airflow is best for nicotine salts?

Nicotine salts are commonly used with lower-powered MTL pod systems, where a restricted airflow is often preferred. Always follow your device and e-liquid manufacturer's guidance.

Why is my MTL vape too airy?

Your airflow may be too open. If your device has adjustable airflow, close it gradually until you reach your preferred draw.

Why is my vape draw too tight?

Check that the airflow isn't almost completely closed and inspect the airflow path for condensation or debris.

Does airflow affect flavour?

Yes. Changing airflow can alter how flavour and vapour are perceived, although coil, e-liquid, wattage and device design also have a major effect.
