The XiKAR Crystal 250 humidifier has a special polymer gel that absorbs up to 450 times its weight in fluid. That means better cigar humidification and less work for you. DO NOT use 50/50 solution with this unit. It is designed to work best with XiKAR's own PG solution, or plain distilled water.
I have used these for years in my table top humidors and no need to use any special solution. Use distilled water only and let it set for 15-20 minutes to absorb the water before placing back in your humidor. Will keep your humidor around 70% +/- 1% for up to 3 months before needing to be refilled.
Right away it would not keep 70% - average 62%, humidor currently holds about 150 - capacity is are 200 sticks. Used the Xikar solution from the start. It was replacing an order humidifier so the humidor was seasoned and already at 70%.
Used with Xicar proprietary solution, these humidifiers work just fine ? for a little over a year. Then the humidity levels slowly drop off, and Xicar tells you it s time to replace them. Instead of spending the $$ on these, you d be better off with Boveda packs or simple beads and distilled water.
Do NOT use water or regular PG solution, use Xikar brand fluid only. I ve had these in the past and used PG and it didn t absorb properly. I use only Xikar solution and they work flawlessly.
