This means that the e-liquid is contained within the cartridge itself and cannot be manually refilled. Replacing a cartridge is simple - when you start to notice a change in the way your vape pen is performing, it’s time for a new cartridge. These changes can include less vapour production and a weaker flavour.
To replace your cartridge, unscrew the used one and throw it away responsibly. Then take your new cartridge and screw it onto the battery. Make sure that the cartridge is attached securely as this could affect the vapour production.
E-liquid bottles are used to refill Open System devices like the blu PRO. The term Open System refers to the fact that the clearomiser (where the e-liquid is stored) can be topped up manually. The blu PRO has a clear window on the side of the device so you can see when your e-liquid has run out. To refill your blu PRO, follow these steps:
It is important to keep e-liquid out of the centre tubing, as this can lead to flooding. This is when e-liquid gets into the mouthpiece and can result in a bad taste when vaping. You can sometimes notice flooding when your vape pen starts making a gurgling sound and produces less vapour than normal.
When refilling your vape pen this way, it is a good idea to do so over a paper towel so that any spilled e-liquid can be easily mopped up. Refilling your device also provides a good opportunity to clean the mouthpiece, as this will make sure that you continue to get a smooth draw from your device. To do this, simply place a tissue inside the back of the unscrewed mouthpiece and blow through it.
To make sure that your device continues producing the best flavour and has a consistent vapour production, it is recommended that the clearomiser itself is replaced every 10 refills.
