Open pod system e-cigarettes are popular for their refillable pods and versatility. However, leakage is a common issue faced by users. This article explores some of the main causes of leakage and provides practical tips to prevent it.

1. Choose the Right E-Liquid

One major cause of leakage is using an e-liquid that's not suitable for your device. Open pod systems are typically designed for higher nicotine salts and e-liquids with higher viscosity. Using low-viscosity e-liquids can result in liquid leaking through larger airflow holes. Therefore, it’s important to choose e-liquids with a 50/50 or 60/40 VG/PG ratio.

2. Avoid Overfilling

Overfilling the pod is another common cause of leakage. Each pod has a maximum fill capacity, and exceeding this limit can lead to overflow, clogging the airflow channels and increasing the risk of leakage. Always follow the manufacturer’s guidelines and fill your pod with the correct amount of e-liquid.

3. Regularly Inspect Seals and O-Rings

Damaged or worn-out seals are another frequent source of leaks. Most open pod systems rely on silicone seals to maintain a tight closure. If these seals become loose or damaged, they can cause leakage. It’s important to regularly inspect these seals during refills or cleaning, and replace any damaged parts.

4. Prevent Extreme Temperature Changes

E-liquids are sensitive to temperature, and rapid changes—especially if the VG/PG ratio is unbalanced—can cause the e-liquid to expand, creating pressure inside the pod and leading to leaks. Avoid exposing your device to extreme temperatures, such as leaving it in direct sunlight or inside a hot car, to minimize the risk of leaks.

5. Be Mindful of Inhalation Force

Incorrect inhalation technique can also contribute to leakage. Taking excessively strong draws can cause liquid to flow through the airflow channels too quickly, resulting in the e-liquid not fully vaporizing and leading to leakage. Users are advised to use steady, moderate inhalation to reduce this risk.

6. Regularly Clean Your Device

Residual e-liquid build-up in the airflow channels, drip tip, or airflow holes can lead to leaks if not cleaned regularly. Using a cotton swab or tissue to clean your device, especially after refills or heavy use, can help prevent leakage.

7. Opt for Devices with Leak-Proof Designs

Many manufacturers are now addressing leakage issues by designing open pod systems with improved airflow configurations and multi-layer leak-proof technology, such as double silicone seals and more precise airflow channels. If leakage is a persistent problem, consider switching to a device with these features.

8. Consider Side-Fill or Top-Fill Devices

Side-Fill Devices: Side-fill systems allow for more direct and even distribution of e-liquid, reducing the chances of liquid pooling and leading to leaks. For example, the Summo Ultra1 Pro features a side-fill system that minimizes the risk of leakage.

Top-Fill Devices: Top-fill designs utilize gravity to help the e-liquid naturally flow downwards, ensuring even coverage and reducing wear caused by dry spots.

Conclusion

Preventing leakage in open pod systems isn’t complicated. By following proper usage practices, maintaining your device, and using the right e-liquids, you can significantly reduce the risk of leaks and enjoy a smoother vaping experience.
