Vape Coils Explained: Ohms, Mesh and Lifespan
The coil is the heart of any refillable vape — it heats the e-liquid into vapour. Understanding coils helps you get better flavour, bigger clouds and longer life from your device. Here is a plain-English explanation.
What does ohms (resistance) mean?
Coil resistance is measured in ohms. Lower-resistance coils (below 1.0 ohm, called sub-ohm) run at higher power for bigger clouds and warmer vapour, ideal for direct-to-lung vaping. Higher-resistance coils (above 1.0 ohm) suit mouth-to-lung vaping and nic salts.
Mesh vs standard coils
Mesh coils use a single sheet of perforated metal instead of a traditional wire wrap. This gives a larger, more even heating surface, producing better flavour and lasting longer. Mesh is now the standard in most quality coils and disposables.
How long do coils last?
A coil typically lasts one to two weeks with regular use, though this varies with the e-liquid, power and how often you vape. Sweet, dark e-liquids shorten coil life. When flavour drops off or tastes burnt, it is time to replace.

Frequently Asked Questions
What do ohms mean on a vape coil?
Ohms measure a coil's electrical resistance. Sub-ohm coils (below 1.0 ohm) produce bigger, warmer clouds for direct-to-lung vaping, while higher-ohm coils suit mouth-to-lung vaping and nic salts.
Are mesh coils better?
Yes, generally. Mesh coils heat more evenly across a larger surface, giving better flavour and longer life than traditional wire coils. They are now the standard in most quality devices.
How often should I change my vape coil?
Most coils last one to two weeks. Replace your coil when the flavour fades, tastes burnt, or the vapour drops off. Sweet e-liquids will shorten coil life.
