Your iClear 30 clearomizer will have "replaceable coil heads". There are at least three versions of the iClear 30, so after determining which version you have you can purchase replacement heads for it.
The original
iClear 30 had large strings of wicks hanging freely from the top of the tank. A top dual-coil design.

The
iClear 30S had a metal tube surround those strings wicks with multiple holes in the tube. Still a top dual-coil design. It uses a different replacement coil than the original iClear 30.

The
iClear 30B is the third generation of iClear 30. It uses yet another type of replacement coil ( dual-bottom coil).

iClear 30B.
To be clear (pun not intended), the replacement coils for the three versions of iClear 30 are NOT intercompatible with one another. You can find how to replace the coils by doing a YouTube search once you know which tank you have.
