Mesh Coils vs Regular Coils

Have you been browsing replacement coils and noticed that some say mesh and some do not?  
 
The question is, does it matter? It does, though probably not in the complicated way you might expect. The difference comes down to how the heating element is built, and once you understand that, the rest makes sense fairly quickly. 

The heating element is the key

Every coil has two components: a wire that heats up when power passes through it, and a cotton wick wrapped around or against that wire to soak up your e-liquid. When you fire the device, the wire heats the liquid in the cotton and turns it into vapour. 

 In a regular coil, that wire is a single thread twisted or looped into a spiral shape. In a mesh coil, the wire is replaced with a flat strip of metal that has been perforated into a grid pattern, a bit like a fine gauze. That is the only structural difference, but it changes quite a lot about how the coil behaves. 

Why the shape of the wire matters 

A spiral wire touches the cotton in a relatively small number of contact points. A mesh strip, with its open grid structure, makes contact across a much wider, more even surface. That increased surface area is what drives most of the practical differences between the two. 

More surface contact means the liquid vaporises more evenly across the whole wick rather than being concentrated around a few tight coils of wire. It also means the heat is distributed more consistently, which reduces hot spots, lowers the risk of a dry hit and generally produces a cleaner, more even draw.

How they compare in practice

1. Flavour - Mesh tends to produce noticeably better flavour, particularly on the initial draw. Because the liquid is being heated across a broader area simultaneously, you get a fuller, more rounded taste from the same e-liquid. Regular coils can still deliver good flavour, especially at lower resistances, but mesh has a clear edge here for most vapers.
   
   
2. Vapour production - Mesh also has an advantage on vapour output. The larger surface area vaporises more liquid per draw, which means denser clouds for the same wattage compared to a regular coil of the same resistance. For sub-ohm vapers chasing cloud production, mesh coils are now the standard for exactly this reason.
   
   
3. Ramp-up time - Regular spiral coils, particularly dual, triple and quad core versions, can take a noticeable moment to heat up fully before you get full vapour on the draw. Mesh heats much faster because the flat strip reaches temperature almost instantly across its full surface. If you have ever noticed a slightly thin start to a puff that fills out as you inhale, a slow ramp-up is usually why. Mesh largely removes that.
   
   
4. Coil longevity - Mesh coils generally last longer. Because the heat is spread out rather than concentrated on a few tight wire loops, the cotton degrades more slowly and the metal itself is less prone to the kind of localised overheating that shortens coil life. Regular coils, especially multi-core ones running at high wattage, tend to need replacing more often.
   
   
5. Dry hits - Dry hits happen when part of the cotton fires without enough liquid to vaporise. With regular coils, the heating is more localised, so a small area of dry cotton is more likely to scorch on contact with the wire. Mesh distributes heat more evenly, which gives the wick a bit more tolerance before a dry patch becomes a burnt patch. It does not make dry hits impossible, proper priming and keeping the tank topped up still matters, but mesh is more forgiving. 

Where you are most likely to find each type

• Mesh coils have become the default in most sub-ohm tanks. If you are running a device at 40W or above with a tank like the Aspire Odan, you will almost certainly be using mesh. The Aspire Odan Mesh coil comes in 0.2Ω, 0.3Ω and 0.18Ω options, all available at Tidal Vape, and is a good example of what a purpose-built sub-ohm mesh coil looks like.
  
  
• The Voopoo PnP range is another example where mesh and regular coils sit alongside each other for the same device. The PnP VM1 at 0.3Ω and PnP VM6 at 0.15Ω are both mesh options within the PnP system, designed for higher wattage and maximum vapour. If you prefer a tighter, lower-power draw on the same kit, a regular-wire PnP coil like the R1 at 0.8Ω gives you that option instead.
  
  
• In the mouth-to-lung category, regular wire coils have traditionally dominated because the lower wattages involved did not justify the mesh design. That is starting to change. The Aspire Nautilus XS Mesh at 0.7Ω is a good example of mesh making its way into MTL setups, bringing the flavour and ramp-up benefits to a tighter, cigarette-style draw.
  
  
• For heavier sub-ohm use, brands like Freemax and Geekvape have taken mesh further. The Freemax Triple Mesh Pro at 0.15Ω and the Geekvape Supermesh X2 at 0.3Ω both use multi-layer mesh designs that stack several strips of mesh together, increasing surface area even further. Both are stocked at Tidal Vape and suited to high-wattage setups where flavour and cloud production are the priority.

Multi-core regular coils: where they still make sense 

Dual, triple and quad core coils, where several regular wire spirals are bundled together inside the same coil head, are still around and still have their place. They produce a hot, intense vape with strong throat hit and good cloud production. For some vapers, particularly those who prefer a punchy, warm draw, they still deliver something mesh coils do not quite replicate. 

The trade-off is that they run hotter, drain batteries faster and tend to need replacing more often than equivalent mesh coils. They are also generally more demanding on your liquid, working best with thicker high-VG blends at wattages that some smaller devices cannot reach. 

If you are using a compact mod or want to extend battery life between charges, mesh is usually the more practical choice. If you are on a full box mod and specifically want that aggressive, warm vape that multi-core coils produce, they are still a legitimate option. 

Which one should you choose? 

For most vapers, mesh is the better default. Better flavour, faster heat-up, longer life and lower risk of dry hits are a strong combination. The only real reason to go with regular coils is if your device only accepts them, if you specifically want the style of vape a multi-core regular coil produces, or if you are on an older kit that predates the widespread move to mesh. 

The simplest way to decide is to look at what your kit recommends. Most tanks and pods have a coil range listed in the manual or on the product page, and within that range you will usually find both options if the device supports them. Try mesh if you have not already. Most people who do find it hard to go back. 

Mesh coils at Tidal Vape 

Tidal Vape stocks mesh coils across all major brands. Whether you are running an Aspire, Voopoo, Vaporesso, Freemax or Geekvape device, the coils section on the website lists compatible options with resistance values noted on each product page. 

The Vaporesso GTX Mesh coil is another option worth knowing about, available in 0.2Ω, 0.3Ω and 0.6Ω and suited to the GTX range of tanks and kits. If you are upgrading from a regular coil to mesh for the first time and want a noticeable improvement in flavour without changing your device, it is a good place to start. 

Orders over £24 qualify for free next day delivery, with same-day dispatch on anything placed before 1pm. If you want to talk through which coil is right for your setup, staff in any of Tidal Vape's 34 stores across the UK can point you in the right direction on the spot.
