Cigar Oasis Refill

This is the refill for the Cigar Oasis electronic humidifier. It's a self contained cartridge that has distilled water. It lasts about 2-4 months depending on often a humidor is opened and size of humidor. I reuse the water cartridge for several times by filling the it with distilled water and then draining the excess. The manufacturer doesn't recommend due to mold concerns, but I never had an issue with this. So, you use your own judgement.
