How Airflow Resistance Shapes Your Inhale Experience (More Than You Think)

When vapers talk about what makes a good vape, they usually mention flavour, cloud size, and battery life. But one of the most critical factors is almost invisible: airflow resistance. How easily air moves through your device fundamentally changes every aspect of your experience – from throat hit intensity to vapor temperature to how satisfying each puff feels. Understanding airflow resistance is the key to finally getting your vape to feel exactly how you want it.

Airflow resistance directly determines your inhalation style. Mouth-to-lung (MTL) devices have tight airflow – you draw vapor into your mouth first, then inhale to your lungs. This mimics cigarette smoking and delivers concentrated throat hit. Direct-to-lung (DTL) devices have open airflow – you inhale vapor straight into your lungs, creating massive clouds but weaker throat hit.

Airflow isn't just about draw resistance – it directly affects vapor temperature. Tight airflow reduces the amount of air mixing with the vapor, which means less cooling. The result is warmer, denser vapor that feels more intense on the throat. Open airflow allows more cool air to mix with the vapor, producing cooler, airier vapor that feels smoother but less "powerful." This is why MTL devices often feel "hotter" than DTL devices running at the same wattage.

The right airflow for you depends entirely on what you want from your vape:

• If you're quitting smoking: Choose tight airflow (MTL). The restricted draw and concentrated throat hit will feel familiar and satisfying, making the transition easier.
• If you want massive clouds: Choose open airflow (DTL). Wide airflow allows you to inhale larger volumes of vapor, producing impressive cloud production.
• If you want to taste every flavour note: Moderate airflow (between MTL and DTL) often works best – enough air to carry flavour without diluting it too much.
• If you're unsure: Get an adjustable airflow device. You can experiment and find your sweet spot.

Devices with adjustable airflow let you experience multiple styles in one device. The RELX Infinity 2 features three adjustable power modes – but more importantly, when paired with different pods and inhalation techniques, it can deliver both MTL and restricted-DTL experiences. Being able to fine-tune your airflow means you're not locked into a single style.

Pro tip: Start with a tighter setting and gradually open the airflow as you get used to vaping. Many ex-smokers find tight airflow essential in the beginning, then gradually prefer more open airflow over time.

Can I change the airflow on my disposable vape?
Most disposables have fixed airflow. If you want adjustable airflow, choose a refillable pod system like the RELX Infinity 2.

Why does my vape feel too "airy"?
Your airflow is too open for your preference. If your device has adjustable airflow, close it partially. If not, consider a device with tighter draw (like RELX MagicGo).

Does tighter airflow waste e-liquid?
No – tighter airflow actually uses e-liquid more efficiently because less air dilutes each puff. You may find yourself taking shorter draws.

Which airflow is better for quitting smoking?
Tight airflow (MTL) is almost always better for smoking cessation because it mimics the draw of a cigarette and provides satisfying throat hit.

Can I do MTL on a DTL device?
You can, but it won't feel right. DTL devices have airflow that's too open for a satisfying MTL draw. Choose a device designed for your preferred style.
