Sub Ohm Vaping’s Second Wind: The Rise of Mesh Coils

Even if you’re a casual vaper, you’ve probably heard about the magical properties of mesh coils. The tried and tested traditional ‘wire coil’ has been around for over 15 years now after Chinese pharmacist Hon Lik developed the first prototype of the modern e cigarette. That’s not to say there hasn’t been innovation in the e cigarette industry – box mods have been improving in quality and features for years, and sub ohm tanks have dramatically improved since their first inception. The mesh craze seems to promise a breath of fresh air in the face of a slowing industry. Are mesh coils all they’re hyped up to be?

Okay, so why are mesh coils so great? One large part is the surface area. Traditionally prebuilt coils are made by winding wire, usually kanthal or a SS316L alloy, around a bit to form a coil. The coil is then wrapped in a cotton cylinder and metal chassis to form an atomizer. This method works great for the most part, but there are several drawbacks.

non mesh coils

Most sub-ohm atomizers require a high power output to vaporise e liquid to an adequate level. This usually results in a very high temperature ranging anywhere from 200ºC to 300ºC. Cotton is able to withstand this heat for the most part thanks to the high heat capacity of e liquid, which absorbs the majority of the heat during vaporization. In a lot of cases though, traditional coils tend to have a lower lifespan. That’s because the high temperatures are concentrated into such a specific area, singing the cotton. This makes way for muted flavour, spitting, or worse: dry hits.


Mesh Coils

Mesh coils aim to solve this problem by utilising the surface area of the cotton, rather than condensing the heat into such a small space. Mesh’s surface area solution is meant to provide a massively improved vapor production and a large increase in flavour. Many manufacturers such as FreeMax have even moved on from a single mesh configuration. Freemax’s Mesh Pro has been making the rounds lately with their ‘Quadruple Mesh’ coil, which is supposedly capable of handling up to 140W of power. And that’s without burning.


Our Verdict

So are mesh coils all they’re cracked up to be? Our opinion is that it’s too early to tell. While we’ve had nothing but good feedback in our B+M, the ecig industry moves fast. Top players in the industry have been moving their standard coil set over to mesh for a few months now. Aspire even released new mesh coils for the 2 year old Cleito 120. It’s going to be a while before we know who owns the mesh game, but for now the FreeMax Mesh Pro is our favorite. With the cleverly designed coils (complete with a reservoir), easy fill top cap and 18 color options, it’s a no brainer. Check out our FreeMax Mesh Pro bundle deal.

Our staff use exclusively rebuildable atomizers at this point, but we were very impressed by the faithful flavour of the mesh coils in the Freemax. The large airflow also allows for a satisfying intake without any harshness or dry hits. Mesh coils might not be anything to shout about if you’re a DIY/hobbyist, but they’re definitely a win for the everyday vaper.
