At their core, all vapes work the same way, using heat to create vapour from the e-liquid, which is then inhaled. Of course, different types of vapes will achieve this in slightly different ways, but the basic principle is always the same. In a refillable vape pod, there are usually three key parts - the casing, the tank and the vape coil. The casing is the part that holds the tank and coil, and is the piece that connects your pod to your vape device (the bigger bit that contains the battery, any screens and controls and the firing mechanism). Your casing will also have a small opening or mechanism that allows you to access the vape tank. The tank is where your e-liquid actually sits when you're not using your vape, and is the part of the pod that you'll actually refill. Like all vapes, the liquid in the tank is then heated by the coil, which also comes in your open-system cartridge. The coil is the part of your vape that controls how hot your e-liquid gets and the resistance of your vape (whether you are vaping normally or are sub-ohm vaping).

When you use vape mods and box mods, you need to replace and maintain your coils on a regular basis. You'll need to clean your tank every month or so and replace it every year or so, and depending on how much you vape, plus you may need to replace your coil every few weeks, or even every few days. When you use vape pods, on the other hand, you don't need to worry about cleaning or maintaining your parts, you simply refill again and again, before throwing out the whole pod and starting again. Depending on the type of refillable pod you choose and how often you vape, they can last anywhere from five to fifty refills!

This means that, particularly when compared to pre-filled pods, refillable pod kits are much more eco friendly

, as they create considerably less plastic waste than pre-filled pods. Not only do they need to be replaced and thrown away as often, they also don't require as much actual plastic use, as you can buy up to 10ml bottles of e-liquid, compared to only 2ml e-liquid pods. You also use less packaging when it comes to replacing your coils and tanks as it's all in one simple cartridge! Great news for the environment, great news for your wallet and great news for your vape experience!
