How Often Should You Change Vape Coils? A Practical Guide for 2025

If your vape starts tasting burnt, producing less vapor, or gurgling during use, it might be trying to tell you one thing: it's time to change your coil. But how often should you change it? The answer depends on your device, vaping habits, and the type of e-liquid you use. In this guide, we break it down simply for vapers of all levels.

How Long Does a Vape Coil Typically Last?

For most users, a vape coil lasts 5 to 10 days with regular use. However, heavy vapers or those using high-sweetener e-liquids may find their coils burn out faster—sometimes within 3–5 days. On the other hand, MTL (mouth-to-lung) coils or mesh coils used with low-power devices may last up to 2 weeks if properly maintained.

5 Signs It’s Time to Replace Your Coil

1. Burnt or metallic taste

2. Noticeably less vapor production

3. Gurgling or leaking

4. E-liquid tastes different or dull

5. Dark or crusted coil cotton when inspected

If you experience any of these signs, it’s better to replace the coil than to continue vaping with it—especially for your lungs and flavor experience.

What Affects Coil Lifespan?

• E-liquid ingredients: Sugary or sweetened juices can gunk up coils faster.

• Vaping frequency: The more you vape, the shorter the lifespan.

• Power settings: Vaping at higher wattage burns through coils faster.

• Priming technique: Not priming your coil properly can burn it on first use.

️ How to Make Your Coil Last Longer

• Always prime your coil before first use.

• Let the coil soak for 5–10 minutes after filling the tank.

• Avoid chain vaping to prevent overheating.

• Use clean, high-quality e-liquid and stick with recommended wattage.

How Many Coils Should You Keep on Hand?

If you vape regularly, having a 2–4 week supply of coils at home is a good idea. For MTL users, that might mean 2–3 coils; for DTL vapers, you might need 4–6 depending on usage.
