A clearomizer on the other hand, does not possess any such filament. Rather, the coils used with clearomizers have wicks attached to them. These wicks then absorb the e-liquid and feed it to the atomizer coils. Clearomizers also have large plastic e-liquid reservoirs that can hold various volumes of e-liquid. And lastly, when coming to the discussion of a Glassomizer. They function is exactly the same way as a clearomizer does, except for one sole distinction. The e-liquid reservoir of a clearomizer is made up of plastic while that of a Glassomizer is made up of Pyrex glass. The benefit of this is that over time the plastic one erodes due to the acidity that is contained within the e-liquids but the Pyrex glass never get eroded.
