Spitback is one of the most annoying things that can happen when vaping. No one wants to deal with hot e-liquid suddenly popping into their mouth. Whether you’re a beginner or a seasoned vaper, spitback is a problem you’ll want to avoid. That’s why choosing the right coil matters. If you’re shopping at How To Vape in the UK, two coil types stand out—Innokin Zenith Coils and Vaporesso GTX Coils. But which one is more prone to spitback?
Let’s dive into a detailed comparison of both coil systems and see how they stack up when it comes to controlling spitback and offering a smooth vape.
What Is Spitback and Why Does It Happen?
Before comparing the two, it’s important to understand what spitback is. Spitback happens when e-liquid pools on the coil instead of being vaporized. This excess liquid gets heated rapidly and pops back up through the mouthpiece. It’s caused by flooding, over-priming, drawing too hard, or using the wrong power setting.
Coil design plays a huge role in preventing spitback. The right airflow, wicking material, and heating element can drastically reduce the risk.
Innokin Zenith Coils: Built for Stability
Innokin Zenith Coils, available at How To Vape, are engineered for consistent mouth-to-lung (MTL) vaping. These coils are popular for their no-leak and no-fuss experience.
Design Focused on Leak Prevention
Zenith Coils are designed with a vertical coil layout and tightly packed organic cotton. This helps absorb e-liquid evenly and prevents flooding—a major cause of spitback. The airflow is also fine-tuned for MTL vaping, meaning the vapor path is tighter and more controlled.
Low-Wattage Performance
Most Zenith Coils operate between 10–20W, reducing the chance of overheating or sizzling. Lower power reduces the chance of hot e-liquid jumping out of the coil.
Spitback Control
Because of their optimized design and low output range, Innokin Zenith Coils are less prone to spitback. They’re especially good for vapers who use higher PG or nicotine salt e-liquids, which are thinner and less likely to flood the coil.
Vaporesso GTX Coils: Power and Versatility
Vaporesso GTX Coils, also available at How To Vape, are known for their versatility. Whether you’re into mouth-to-lung or direct-to-lung (DTL) vaping, GTX coils offer multiple resistance levels and coil structures.
Mesh Coil Technology
Many GTX coils feature mesh designs, which heat e-liquid more evenly. That helps minimize the risk of hot spots, which can cause spitback. However, mesh coils are more powerful and are often used at higher wattages, especially the 0.2Ω or 0.3Ω coils.
Advanced Wicking System
GTX coils use a combination of flax cotton and non-woven fabric, which holds more e-liquid and boosts flavor. This combination soaks juice rapidly—but if the coil floods or the power isn’t high enough to vaporize the liquid properly, spitback can occur.
Spitback Risk
GTX coils are slightly more prone to spitback, especially when underpowered or used with high-VG e-liquids at low wattage. Sub-ohm vaping also involves more e-liquid volume and air pressure, increasing the chances of flooding if not set up properly.
Head-to-Head: Spitback Comparison
Let’s break it down further to see how Innokin Zenith Coils and Vaporesso GTX Coils compare in spitback prevention.
1. Coil Structure and Airflow
Zenith Coils feature a more enclosed coil structure, limiting the amount of e-liquid that can pool on the coil. GTX coils, on the other hand, have a larger airflow design, especially in the sub-ohm variants. That wider structure can allow more e-liquid to splash upward if not vaporized completely.
Winner: Innokin Zenith Coils
2. Wattage Range
Zenith Coils operate at lower wattages, meaning less chance of overheating or excess condensation. GTX Coils often run at higher wattages, which require more attention to airflow and juice ratio.
Winner: Innokin Zenith Coils
3. Juice Compatibility
Zenith Coils work best with thinner 50/50 or high-PG liquids, which wick cleanly and vaporize efficiently. GTX Coils are more suitable for high-VG liquids, which are thicker and can sometimes flood the coil if not wicked correctly.
Winner: Innokin Zenith Coils
4. Coil Flooding and Over-Priming
Due to its tighter wicking and resistance to flooding, Zenith coils rarely spit even after priming. GTX coils, when over-primed or filled incorrectly, may hold more juice than needed and cause spitback on first use.

How To Reduce Spitback With Both Coils
Regardless of the coil, spitback can still happen with improper use. Here are quick tips to prevent it:
-
Prime your coils properly: Use a few drops on the cotton before installation.
-
Don’t overfill the tank: Leave some airspace.
-
Use the correct wattage: Always stay within the coil’s recommended range.
-
Puff gently: Don’t draw too hard, especially with MTL coils.
-
Avoid high-VG liquids in MTL setups: Stick to what the coil is designed for.
Which One Should You Choose at How To Vape?
If avoiding spitback is your top priority, Innokin Zenith Coils are the better option. Their structure, lower wattage, and cotton density offer excellent protection against spitback. They’re perfect for beginner vapers, ex-smokers, or anyone who prefers a smooth, quiet vape.
If you’re chasing clouds and flavor and don’t mind fine-tuning your settings, Vaporesso GTX Coils can still give a great experience. Just make sure your device matches your coil type, especially if you’re using sub-ohm variants.
Final Verdict
Innokin Zenith Coils are clearly less prone to spitback, thanks to their MTL design, tight airflow, and consistent wicking. They offer peace of mind with every puff and are especially suitable for vapers who prefer a no-fuss experience.
Vaporesso GTX Coils, while more powerful and flavorful, need a little more attention to prevent spitback—especially at lower wattages or with high-VG juice.
Whichever you choose, How To Vape in the UK has both coils available with fast delivery and authentic quality. Pick the one that suits your vaping style, and enjoy a spitback-free session every time.
