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.
