Mesh coil - how the modern vaporiser head works

A mesh coil is an atomiser head whose heating element consists of a thin, perforated metal strip – usually made of Kanthal or stainless steel mesh. This mesh is placed on top of the cotton and heats up evenly across the entire surface whilst vaping. In contrast, a classic coil uses a wire wound into a spiral, which only releases heat at specific points.

The key advantage lies in the geometry: a mesh atomiser has a significantly larger heating surface whilst being lighter in weight. The metal reaches its operating temperature more quickly (ramp-up), distributes the heat more evenly across the coil and puts less strain on the e-liquid. As a result, flavours – particularly fruit and dessert notes – taste more precise and less ‘burnt’.

Mesh coils come in two designs: as pre-built atomiser heads that screw in (e.g. for tanks such as the Nautilus, Zeus or TPP) and as mesh strips for rebuildable atomisers (RTA, RDA). For the vast majority of users, pre-built heads are the more practical choice.

When you take a puff on the mouthpiece, the mod sends electricity through the mesh. The mesh heats up to 200–250 °C in a fraction of a second and vaporises the e-liquid soaking the surrounding cotton. Because the heat is distributed over a wide area, less power is required per unit area – at 0.2 ohms, you can often vape at 40–60 watts, whereas a traditional coil would need 70 watts.

Mesh coil in a sub-ohm tank

Typical resistances range between 0.15 and 0.4 ohms. These coils are designed for direct-to-lung (DL) vaping, i.e. for dense vapour with an open airflow. For this, you need e-liquids with a high VG content (70/30 or higher) and ideally 3 mg of nicotine or less.

Mesh coil in a pod system

In pod systems such as Caliburn, Vinci or Xros, mesh coils usually operate at 0.6–1.0 ohms and 10–20 watts. They are ideal for nicotine salt e-liquids and MTL (mouth-to-lung) vaping, i.e. taking a drag just like with a cigarette. Here too, mesh delivers more flavour than a wrapped coil.

The question of mesh vs standard coil is easily answered – but within the world of mesh, there are differences you should be aware of:

• Resistance (ohms) suitable for your setup: Below 0.5 ohms, you’ll need a powerful mod and DL airflow. Above 0.6 ohms is suitable for pods and MTL. Always check the wattage range printed on the coil.
• Compatibility: Mesh coils are not universal. A GTX coil will not fit in a TPP tank. Always buy coils that are explicitly specified for your tank or pod.
• Mesh material: Kanthal is the standard; stainless steel (SS316) also allows for temperature control. For normal wattage vaping, the material makes little difference to the flavour.
• Priming: New mesh coils must be primed before the first puff. Apply 4–6 drops of e-liquid directly onto the visible cotton, screw the coil in, fill the tank and wait 5–10 minutes. Otherwise, you risk a dry hit.
• Lifespan: A mesh coil lasts 7–21 days, depending on the e-liquid and power setting. Highly sweetened flavours (dessert, menthol with sweetener) noticeably shorten the lifespan because the sugar caramelises and the cotton becomes sticky.

A common mistake: setting the wattage too high. If the coil is rated at 40–60 W, don’t set it to 80 W – the mesh will overheat, the cotton will scorch and the flavour will become bitter.

Is a mesh coil really better than a standard coil?

In terms of flavour, vapour production and lifespan, yes. The mesh coil distributes heat more evenly and puts less strain on the e-liquid. If you’re specifically looking for a classic, harsh draw or own an older tank, you can stick with traditional coils.

How long does a mesh coil last?

Realistically, 1 to 3 weeks with daily use. Light fruit and tobacco e-liquids extend the lifespan, whilst heavily sweetened dessert flavours reduce it to just a few days.

Can I clean a mesh coil?

Pre-made mesh heads are virtually impossible to clean properly, as the cotton cannot be replaced. Rinsing with warm water may loosen deposits in the short term, but it is no substitute for a new coil.

What wattage is ideal for mesh coils?

Strictly follow the instructions printed on the coil. Start at the lower end of the range and increase the power in 2-watt increments until the flavour and vapour are right for you.

Mesh coils have audibly transformed vaping: more flavour, more vapour, less power consumption. Anyone buying a new tank or pod system today will almost automatically receive a mesh coil with it – the key is that the resistance, wattage and e-liquid are compatible. In our selection of coils and atomiser heads, you’ll find suitable mesh variants for popular tanks and pods. Take your time to browse and compare the specifications with your current setup before making the switch.
