At the right is one of the early "cartomizers" with a thin plastic wall tank and polyfill. It came with an inexpensive personal vaporizer that I purchased. They were reasonably popular in their day, largely because the eLiquid capacity was considerably more than a regular cartomizer used on a Cig-Alike battery. Needless to say, I threw mine out without using them. The industry has advanced enough to make these redundant (thankfully).
Next on the scene was a distinct improvement. A clearomizer with top coil and wicks that brought the eLiquid from the larger capacity tank to the top coil for atomization. These provided a "warm" vape (the coil is close to the drip tip).
Capacity of these style tanks ranged from 1.0 to 1.8 ml.
They were quite popular and still are in wide use. I found the flavor rendition from some of these clearomizers to be quite good. For the large part, these are disposable. There are some with replaceable coils, but the cost of the entire clearomizer is about the same price as replacement coils.
This may be a general statement and not quite 100% accurate, but overall, BCC and BDC (Bottom Changeable Coils and Bottom Dual Coils) have far advanced the choice and price of clearomizers.
The early bottom coil clearomizers were nearly identical copies of their top wick bretheren as you can see at the right. These are far more practical with the user being able to disassemble and clean most of the components of the clearomizer. Far less disposable and more expensive, these featured coils that imparted distinctly improved eLiquid flavor and throat hit. The vape experience is cooler too since the coil is further away from the drip tip. To this point, most of the tanks are graduated showing the ml of eLiquid remaining in the tank.
The tanks themselves are nearly all plastic. As the industry matured, reports came in of cracked and etched tanks. Some types of eLiquids: citrus, cinnamon, menthols, mints, and some darker eLiquids etched or cracked the plastic portion of the clearomizers. Manufacturers were quick to launch new generations of clearomizers with improved plastic and glass tanks. The safest, of course, being glass. The plastic most prone to craking and etching is polycarbonate (a plastic that we recommend not be used in any circumstances for vaping). Another type of plastic, PMMA, is safer.
At the left is the latest generation of clearomizers.
This one is from a new manufacturer on the scene of vaping, Freemax.
Their line of Silux clearomizers are made entirely of stainless steel and glass. The coil is a BDC style that generates some incredible flavor and throat hit.
Even the drip tip is stainless steel.
Notice at the bottom of the atomizer at the left: a new innovation to clearomizers ... air flow control. One aspect of clearomizers that has frustrated many users is fixed air flow. Many have gone to great lengths to drill out air flow holes, add air flow holes, increase the diameter of air flow tubes inside the clearomizer and even drilling out the drip tip – all to get more air flowing to improve the vaping experience.
Many clearomizers available today feature adjustable air flow with a capacity that was only dreamed of just a few short months ago. Now they are the standard.
The industry has come a long way in a relatively short time.
Throughout our reviews, we look at the features, advantages, disadvantages and value of clearomizers.
As part of your vaping experience, clearomizers are the second most important selection (the most important is the eLiquid). Since this involves providing flavor and throat hit, you need to choose wisely.
