For those who aren’t familiar with the term, sub ohm vaping is basically using an atomizer with a coil that has a resistance of less than 1 ohm (hence, “sub ohm”). This results in much higher temperatures than produced by standard atomizers, which means bigger, denser vapor plumes and (most argue) a much more potent flavor experience.
Until recent years, people had to go through a lot of effort to enjoy sub ohm vaping. In order to do it, you had to purchase a mod, Nichrome or Kanthal wire, batteries and organic cotton to name a few things. New sub ohm tanks eliminate the need for piecing together your own system, and many are compatible with just about any mod that operates at the right wattage.
The Aspire Cleito 120 is one of the first available sub ohm tanks. This tank combines a stainless steel atomizer, durable replaceable Pyrex tube, organic cotton wick, adjustable airflow, and a specialized coil system that produces a smooth, strong hit and billowy clouds of vapor. The Aspire Cleito replacement coil has a very low resistance (0.16Ω). Replacing the coil is simple. Remove the top cap, Pyrex glass tube, and the base of the tank. Next, unscrew the used coil and exchange it for a new one. Set the tube back in place, making sure the bottom is secured to the O-ring, forming a good seal. Finally, refill the tank, and screw on the top cap.
You will enjoy your E-cig more with an Aspire Cleito replacement coil that is changed frequently. If you are a moderate to heavy vaper, every 1 to 2 weeks is usually recommended. If you’re a light vaper, you might be able to get away with 3 to 4 weeks, but you will probably notice a decline in vapor quality and quantity. Flavor purists often exchange their coils every time they switch between juices. One thing is definite, the fresher your tank, the cleaner the taste.
A few final pointers for sub ohm vaping, choosing the right e-liquid is extremely important. The high temperatures produced by low resistance coils often overpower juices that have low-quality ingredients, the wrong balance of propylene glycol (PG) and vegetable glycerin (VG), or even too high a concentration of nicotine. The ideal balance of PG and VG for sub ohm vaping is somewhere between 70/30 PG/VG and 80/20 PG/VG. Most vapers also recommend that you use liquids with nicotine concentrations of no more than 6 milligrams per milliliter. As with certain other additives (i.e. poor-quality ingredients), high heats can make nicotine-heavy juices taste overly harsh or burnt.
