Cigar Q&A: How Long do Humidifier Gel Crystals Last?
Do you use humidifier gel crystals, and are you wondering how long they last?
For the answer to this question I emailed a contact of mine who markets this very type of product. According to her, “The humidifier gel crystals will last for years (around 10) if they never go completely dry. If the crystals go dry every time before recharging, maybe 1½ – 2 years tops.”
