If you notice your STLTH pod leaking slightly, simply first remove the pod from the battery and wipe off any excess liquid. Next, place a tissue at the top of the mouthpiece and blow through the bottom of the cartridge. The tissue will absorb any condensation. Finally, insert the pod back into your STLTH device, and continue to use it. Pods may leak due to low-temperature conditions, excessive humidity, condensation, or a drastic change of altitude. If you encounter excessive leaking, substitute the affected pod with a new one, and please contact the STLTH Customer Support Team through the Contact Us Page.
