"Ceramic heating elements are toxin free vs the aluminum heating elements. Ceramic heating elements are a must, majority of the best vaporizers on the market are using aluminum. Be aware of this when looking for the best vaporizers. Notice how alloy resistance wires will always state that it reduces outgassing due to the metals used to formulate that specific alloy restsitance wire. The keyword is "reduces", which means it still outgasses dangerous toxins. Many manufacturers make false claims of how there aluminum heating element is safe. We have had into depth conversations with many manufacturers and they are very ignorant to change, stating that their element is free of these aluminum toxin pitfalls. When purchasing you next marijuana vaporizer make sure to purchase one with a ceramic heating element."
