Open and Closed System are the terms used to describe the two main types of vape devices. Both are currently available from blu and work in slightly different ways.
The main difference between Open and Closed System devices is the way the e-liquid is delivered to the heating mechanism. Open System vape pens have a clearomiser which is filled with e-liquid manually, whereas Closed System ones use refills, which come ready-filled with e-liquid and attach to the rest of the device. Open System pens also have a removable mouthpiece, whereas the mouthpiece on Closed System devices is built into the cartridge.
The main three parts of an Open System vape pen are the mouthpiece, the clearomiser and the battery. On some device the wick and coil can be detached; however, on blu vape pens these parts are kept sealed inside the clearomiser.
Cartridge and battery are attached What are the benefits of an Open System vape device? Open System devices are completely reusable as the e-liquid can be topped up once it has run out. Open System e-cigarettes often have a smoother draw. An Open System vape pen also has a more powerful battery, which means that it will last for longer when fully charged.
Closed System devices are ready to vape as soon as they are fitted together and charged. There is no need to refill any e-liquid which means there is no mess when a cartridge runs out and additionally there is no e-liquid to carry around. Once a Closed System vape pen is finished, the vaper can throw the cartridge away.
To get the most from an Open System device, vapers need to be aware of the issue of flavour ghosting. This term refers to the lingering flavour when a vaper decides to change e-liquid. The best way to avoid flavour ghosting is to have different clearomisers for each flavour of e-liquid and change them when you change your e-liquid.
It is recommended that a Closed System device is charged as often as possible, as this will ensure that every draw is flavourful.
The blu PRO™ is an Open System vape pen that works in a similar way as other Open System devices. The clearomiser is filled with e-liquid and then attached to the e-cigarette battery and, after it has been fully charged, the blu PRO can be vaped. The blu PRO comes with optimised coil resistance which gives a purer taste when vaping as well as a refined battery connection which results in a longer battery life.
