The 4 oz jar is used for up to 150 cigars and lasts up to 90 days before refilling.
Xikar humidifiers emit and absorb moisture to maintain 70% relative humidity. Varying humidity levels in a humidor - too much or too little - can destroy cigars quickly, so consistency is most important in preserving and protecting your expensive cigars.
All Xikar humidifiers employ the use of crystals that can absorb 400x their volume (size) of PG solution. When dry, the crystals look like salt grains. When PG solution is added, the crystals saturate and grow to completely fill the humidifier casing.
The Xikar Crystal humidifiers use high grade Sodium based Polyacrylamine. The gel feels dry to the touch and never ever leaks. It is the perfect medium for humidifiers.
To get the best performance out of these Xikar Crystal Humidifier it is always recommended to use the the Xikar PG Humidification Solution.
