What are Open and Closed E-cigarette Systems?

Experienced vapers will know that there are a whole host of different ways to vape. However, anyone new to e-cigarettes may be unsure about the differences between Open and Closed System e-cigarettes. The contrasting features result in different vapes. In this guide we look at what the differences are as well as the advantages of each type.

What are Open and Closed System E-Cigarettes?

Open and Closed System e-cigarettes are the terms used to describe the two main types of e-cigarette. Both are currently available from blu and work in slightly different ways.

The main difference between Open and Closed System e-cigarettes is the way the e-liquid is delivered to the heating mechanism. Open System e-cigarettes have a clearomiser which is filled with e-liquid manually, whereas Closed System e-cigarettes use refills, which come ready-filled with e-liquid, and screw directly onto the e-cig battery. Open System e-cigs also have a removable mouthpiece, whereas the mouthpiece on Closed System e-cigs is built into the e-cigarette cartridge.

The main three parts of an Open System e-cigarette are the mouthpiece, the clearomiser and the e-cigarette battery. On some e-cigarettes the wick and coil can be detached; however, on blu® e-cigarettes these parts are kept sealed inside the clearomiser.

Closed System e-cigarettes are similar, consisting of an e-cig battery and a cartridge. The main difference is that the cartridge cannot be refilled in the same way as a clearomiser can.

What are the benefits of an Open System E-Cigarette?

Open System e-cigarettes, which are sometimes called vape pens, 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 e-cigarette also has a more powerful e-cig battery, which means that it will last for longer when fully charged.

What are the benefits of a Closed System E-Cigarette?

Closed System e-cigarettes, which are also referred to as cig-a-likes, 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 e-cigarette is finished, the vaper can throw the cartridge away.

How can I get the most out of my Open System E-Cigarette?

To get the most from an Open System e-cig, 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.

How can I get the most out of my Closed System E-Cigarette?

It is recommended that a Closed System e-cigarette is charged as often as possible, as this will ensure that every draw is flavourful. Additionally, the blu PLUS+™ Kits come with cases which can be used to store extra e-cig batteries and e-cigarette cartridges.

What is the blu PRO® Open System E-Cigarette?

The blu PRO® is an Open System e-cigarette and works in a similar way as other Open System e-cigs. 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.

What is the blu PLUS+™ Closed System E-Cigarette?

The blu PLUS+™ is a Closed System e-cigarette which works by attaching an e-cigarette cartridge to the e-cig battery. Once the e-cig has been charged, it is ready to use. The blu PLUS™+ Slide Kit comes with a case which can store an extra cartridge, while the blu PLUS+™ Charge Kit can store extra e-cig batteries in addition to charging the e-cigarette when it is in the pack. The cases allow vapers to comfortably carry the blu PLUS+™ around and safely store the kit.
