Discover the common reasons why your vape might be bubbling and learn how to fix vapes that are bubbling and spitting.

Refillable vaping devices—such as e cigarettes that are filled manually using tanks or pods—can sometimes produce a bubbling or gurgling noise during use. This article looks at the potential causes of these sounds, what they might indicate, and how they can be reduced or prevented. It also outlines how VEEV devices use pre-filled, sealed pod systems designed to minimize issues commonly linked to refillable vapes and help deliver a more consistent vaping experience for adult vapers.

What Causes Vape Bubbling?

If your refillable vape starts bubbling, it usually means air and e-liquid (known as e-liquid) are mixing in the wrong way within the device tank during inhalation. This can create a noise and sometimes affects your vaping experience, as excess e-liquid can interfere with the coil’s ability to heat evenly. As a result, vapour production may feel weaker, flavour less intense, or in some cases, small droplets of hot e-liquid (known as spit-back) may reach the mouth. Several factors can contribute to bubbling in refillable vaping devices, such as:

1. Overfilled Vape Tanks

One of the most common causes of bubbling is overfilling the vape tank. When you refill a tank beyond the designated fill line, it can interfere with airflow channels and cause liquid to bubble as it's drawn through the coil. This creates noise and can lead to leakage or flooding of the coil.

2. Thin E-Liquids (PG/VG Imbalance)

The consistency of the e-liquid plays a significant role in how smoothly your vaping device performs, which is determined by the ratio of PG/VG. Propylene Glycol (PG-based liquids) are thinner than Vegetable Glycerin (VG-based e-liquid). If the PG/VG concentration ratio works poorly with your device's design, thin liquids move too freely within the system, increasing the likelihood of bubbling and leaking.

3. Worn-Out Coils or Poor Seals in Vapes

Over time, coils degrade and wicks become less effective at drawing and vapourizing e-liquid evenly. If the coil isn't working properly or if seals in the tank have loosened or worn out, air and liquid can mix incorrectly, leading to unwanted gurgling sounds.

4. Residual E-Liquid Build-Up

Residual e-liquid can accumulate in the tank or coil over time, especially if the device is not regularly cleaned. This build-up can disrupt airflow and cause bubbling noises. Cleaning and maintaining your refillable vaping device regularly can help prevent this issue.

5. Incorrect Wattage Settings

Using the wrong wattage settings can also cause bubbling. When the wattage is set too low, the coil won't heat up sufficiently to vapourize the e-liquid properly. This results in residual liquid that produces a crackling sound. Conversely, setting the wattage too high can overheat the coil, affecting liquid flow and causing bubbling sounds. Finding the optimal wattage range for your coil and e-liquid ensures smooth vapour production.

6. Extreme Temperature and Storage Conditions

Using the vape device at very low temperatures or wattages can sometimes cause e-liquid to condense inside the tank, whereas vaping at very high power overheats the coil, both creating bubbles. Additionally, storing e-liquids in poor conditions—such as exposure to direct sunlight or high temperatures— degrades the liquid, leading to changes in viscosity and increased likelihood of bubbling. Proper storage in a cool, dark place can help maintain e-liquid quality and prevent bubbling issues.

7 Steps to Stop Bubbling in Refillable Vapes

Here’s how to stop your refillable vape from bubbling in 7 quick steps:

1. Avoid overfilling when refilling: Always refill just below the maximum fill line to prevent interference with airflow channels.
2. Use compatible liquids: Stick to PG/VG ratios recommended for your device to ensure proper e-liquid consistency.
3. Replace coils regularly: Ensure proper wicking and airflow by replacing coils as needed.
4. Check seals and connections: Inspect O-rings (small rubber rings that help create an airtight seal in the device) and connections in the tank for wear or misalignment to maintain a proper seal.
5. Opt for a closed-pod system vaping device: If the bubbling issue persists, switching to a closed-pod system vaping device could be an better option. These devices are compatible with pre-filled pods and require no refilling or complex maintenance. However, light cleaning of the mouthpiece or device exterior periodically is recommended. When the e-liquid in your pod has run out, you can simply click a new pod into place and discard the used pod.
6. Adjust wattage settings appropriately: Using the recommended wattage for your coil ensures proper vapourization. Too low wattage can leave excess e-liquid in the coil, causing bubbling, while too high wattage can overheat the liquid and create gurgling noises.
7. Maintain proper storage and temperature conditions: Store your vape at room temperature and avoid direct sunlight and extreme cold.

Why VEEV Vapes Don’t Bubble

VEEV vapes are designed as closed-system devices with non-refillable pods. Because the pods are pre-filled and sealed, this design helps minimize the risk of air gaps or leaks, which can sometimes cause the bubbling effect seen in refillable vapes.

Unlike refillable devices, the VEEV ONE advanced pod-based design minimizes the risk of bubbling through several key innovations:

1. Precision-Filled Vape Pod Technology

VEEV ONE pods are factory-sealed and filled for optimal performance. This ensures balanced pressure and prevents overfilling, which is one of the primary causes of bubbling.

2. Optimized Coil and Wick Design for Smooth Vaping

VEEV ONE and VEEV NOW are designed with oil and wick system that ensures consistent saturation and efficient vapourization.This design prevents dry hits and maintains steady airflow control, reducing the gurgling noises.

3. Smart Airflow System in VEEV ONE Devices

VEEV ONE’s airflow design helps optimize air circulation through the device. This design supports a consistent draw and reduces the likelihood of e-liquid entering unintended areas.

Together, these features make VEEV ONE devices highly resistant to bubbling, ensuring a clean and smooth vaping experience.

Why is my Disposable Vape Bubbling?

While disposable vapes are generally less prone to bubbling than refillable models, bubbling can still occur. Some disposable vaping devices may produce gurgling sounds due to similar issues: poor airflow, degraded coils, or improper use.

However, because disposables are pre-filled and sealed, they tend to offer a more reliable performance out of the box. Still, once a problem arises—like a flooded coil—the device must be discarded.

Why Disposable Vapes Sometimes Gurgle

Gurgling in disposable vapes can occur when:

• The coil becomes flooded from excessive puffing without allowing time for vapourization.
• Airflow channels become obstructed or misaligned.
• The battery power is low, leading to incomplete heating and inconsistent vapour production.

Summary

Bubbling in refillable vapes occurs when air and e-liquid mix improperly, affecting vapour quality, flavour, and overall performance.

Common causes of bubbling:

1. Overfilled tanks: Too much e-liquid can flood the coil.
2. Thin or incompatible e-liquids: Low VG or incorrect ratios can cause flooding.
3. Worn-out coils: Old or damaged coils don’t heat evenly.
4. Poor seals: Loose or damaged O-rings allow leakage and excess liquid in the coil.
5. Residual liquid build-up: Excess e-liquid remains around the coil.
6. Incorrect wattage: Too low causes underheating; too high causes overheating.
7. Improper storage conditions: Heat or pressure changes cause leaking and flooding.

To prevent bubbling, users should fill tanks appropriately, use recommended PG/VG ratios, replace coils regularly, check seals, adjust wattage settings, and store their devices correctly.

For adult vapers who want a smoother, and more consistent vape, closed pod-based systems like VEEV ONE provide a hassle-free alternative. With precision-filled sealed pods and a smart airflow system, VEEV devices are engineered to minimize bubbling, spit-back, and other issues common in refillable and disposable vapes.
