How to Get Rid of Air Bubbles in Dab Cartridges: Complete Guide

Air bubbles in dab cartridges are a common yet frustrating issue that can obstruct the wick and atomizer, leading to inconsistent hits and poor performance.

While typically harmless, eliminating these bubbles will improve airflow and enhance your vaping experience.

This comprehensive guide explains why air bubbles form, how to fix them, and how to prevent them in the future.

What Causes Air Bubbles in Dab Cartridges?

Understanding why air bubbles form in vape cartridges is essential for finding the right solution.

Here are the most common causes:

1. Overfilling or Underfilling the Cartridge

Overfilling increases internal pressure, making it difficult for the e-liquid to settle, while underfilling leaves excess space, allowing bubbles to develop.

2. Defective or Poorly Designed Cartridges

Manufacturing defects such as faulty seals, misaligned coils, and poor assembly can cause airflow issues and bubble formation.

3. Temperature Variations

Exposure to extreme temperature changes can create pressure imbalances, drawing air into the cartridge and forming bubbles.

4. Improper Filling Process

If a cartridge isn’t filled correctly during manufacturing, air may get trapped, leading to persistent bubbles.

5. Altitude Changes

Changes in altitude, such as flying or driving through mountains, affect air pressure inside the cartridge, leading to bubble formation.

6. Rough Handling

Thicker e-liquids are more prone to trapping air bubbles. Choosing a vape with an appropriate viscosity for your cartridge’s coil type can help reduce this issue.

7. E-Liquid Viscosity

Thicker e-liquids are more prone to trapping air bubbles. Choosing a vape with an appropriate viscosity for your cartridge’s coil type can help reduce this issue.

How to Get Rid of Air Bubbles in Your Dab Cartridge?

If air bubbles are causing inconsistent hits, try these methods:

1. Hot Water Dip Method

Attach silicone stoppers (if available) to prevent water from entering the cartridge.

Submerge the cartridge in warm water for 6 to 15 seconds, keeping the mouthpiece out of the water.

The heat will thin the oil, allowing bubbles to escape naturally. Pro Tip: Dry the cartridge with a paper towel before use.

2. Hold the Cartridge Upright

Let the cartridge stand upright for about an hour to allow bubbles to rise and pop naturally.

3. Tap or Shake the Device

Lightly tap the area where you see an air bubble to dislodge it. Gently shake the device to facilitate bubble migration or dislodge them entirely.

4. Create Negative Pressure

Taking a forceful inhale on your vape creates negative pressure, which can push the bubbles to the surface and break them.

5. Preheat the Cartridge

Attach the cartridge to a battery with a preheat function. Double-click the button to preheat, then store it upright to loosen the oil and disperse the bubbles.

6. Use a Hair Dryer

Set the hair dryer to a warm setting and heat the cartridge for one to two minutes.

Stand the cartridge upright for 30 seconds until the bubble rises and escapes.

How to Prevent Air Bubbles When Vaping

Prevention is key to maintaining a smooth vaping experience. Follow these tips to stop air bubbles from forming:

1. Store Your Vape Cart

Correctly Keep your vape cart at room temperature and avoid direct sunlight or freezing conditions.

Store it upright when not in use to prevent uneven pressure distribution.

2. Take Controlled Hits

Avoid long, forceful hits, which create negative pressure.

Instead, take short, steady puffs to maintain consistent airflow and prevent bubble formation.

3. Choose Trusted Brands

Buying from reputable brands ensures high-quality cartridges with proper seals and coil placement, reducing bubble issues.

4. Don’t Overuse the Vape

Allow your vape to rest between hits.

Overuse can create negative pressure inside the cartridge, leading to bubble formation.

Final Thoughts

Don’t worry if you encounter small air bubbles—these are normal during the first use or after refilling. 

They usually appear due to trapped air or temperature changes. 

However, if bubbles persist or become larger, use the abovementioned methods to resolve the issue.

If the problem continues, consider replacing your cartridge with a high-quality alternative.

Following this guide will help you enjoy a smoother, more consistent vaping experience. 

Keep your cartridge in top shape and ensure efficient airflow by taking these preventative measures.
