When To Change A Vape Coil

It goes without saying that if you want your vaping kit to live a long life, you need to make sure you give it regular maintenance checks! One of the critical jobs that you need to carry out regularly is the changing of your coil but how do you know when this needs to be done?    

Regardless of how well you look after your coil, all coils will need to be changed at some point. This can vary from one device to another depending on the resistance of your coil, heat levels, e-liquids and amount of time it is used. However, on average coils should last 1-3 weeks but this help sheet should give you an idea of some signs that may suggest now is the time to change your coil! Some regular vapers change their coils every week, whilst others every 2-3 weeks. There are key signs to look out for and these focus on TASTE, LOOK & SMELL and will be described in more detail below.

Burnt Flavour 

The coil is responsible for heating up the e-liquid in order to produce thick clouds of vapour that are full of flavour. If you experience a burnt flavour this suggests that your coil needs to be changed straight away.

Lack of Flavour

You know what flavours you usually experience with your device so if you start to notice the intensity of flavour is diminishing, this suggests your coil is coming to the end of its life and therefore needs replacing.

Lack of Vapour

As well as flavour, you will also know the levels of vapour you would normally experience when using your vaping device. If you notice this is starting to significantly diminish, this suggests your coil needs to be replaced. Please note that low battery can also cause this to happen, so before changing the coil, ensure this isn’t the reason for lack of vapour.

Discolouration of Cotton

If the cotton wick is looking black or dark brown in colour, this suggests your coil has started to deteriorate and needs to be changed.

Bubbling Sounds

If you hear hollow bubbling sounds whilst vaping this signifies it is time to change your coil.


This doesn’t always signify the need to replace your coil as there can be many reasons for a leaking device. However, it can suggest your coil is worn out and needs to be changed so we recommend you check it to see whether this may be the cause of the leaks.
