A mesh coil is a flat perforated metal strip used instead of a wound wire. It presents far more surface area to the wick, so it heats more evenly and vaporises liquid across a wider area rather than concentrating heat on a thin wire.

Is a mesh coil better than a regular coil?

For flavour and consistency, generally yes. Even heating means fewer hot spots, which produces cleaner flavour and reduces the chance of scorching the wick. Most current disposables use mesh for this reason.

Do mesh coils last longer?

They tend to, because heat is spread rather than concentrated, so the wick degrades more slowly. On a sealed disposable this shows up as flavour holding up further into the device's life.

What Is a Mesh Coil? Why It Changed Disposable Vapes

Q: Does a mesh coil use more e-liquid?

Slightly, since more surface area vaporises more liquid per puff. That is part of why real-world puff counts come in below the rating, and it is a trade for better flavour.

A mesh coil is a flat perforated metal strip in place of a wound wire. It contacts far more of the wick, so heat spreads across a wide area instead of concentrating on a thin filament. That single change is behind most of the flavour improvement in disposables over the last few years.

What the old design did wrong

A wound wire coil heats along its length, creating hot spots where it touches the wick and cooler areas between. Hot spots scorch cotton, which is a direct route to that burnt taste, and uneven heating means flavour varies puff to puff.

What mesh changes

Even heating. More contact area, fewer hot spots, less scorching.
Cleaner flavour. Liquid vaporises at a more consistent temperature, so the profile the manufacturer intended is what you actually taste.
Faster ramp-up. Mesh reaches temperature quickly, so the first puff tastes like the fifth.
Longer usable life. Spread heat degrades the wick more slowly, so flavour holds up further into the tank.

The trade

More surface area vaporises more liquid per puff. That is part of why real-world puff counts land below the printed rating — the arithmetic is in our guide to puff counts. Most people consider better flavour worth it, and it is not really an option any more: mesh is now standard.

Dual mesh

Some higher-capacity devices run two mesh strips. More surface area again, more vapour, and correspondingly faster liquid use. Devices offering a "boost" or "pulse" mode are usually switching between running one or both.

Does mesh change how you should draw?

Slightly. Mesh reaches temperature fast, so long hard draws are less necessary than they were with wire coils — and shorter draws give you more total puffs. That is the same advice as everywhere else on this blog, and it holds for the same reason.
