The XiKAR Crystal 50 humidifier has a special polymer gel that absorbs up to 450 times its weight in fluid. Plus it maintains a perfect 70% humidity. That means better cigar humidification and less work for you. A word of caution, though: USE ONLY XiKAR's own PG solution, or plain distilled water.
I have one in my small humidor and it holds a perfect 70/70 all the time. Highly recommend!12
Please correct your description of this product. The enclosed package insert clearly state that you must use Xikar PG solution with their humidification units in order to maintain RH of 70%; NOT plain distilled water. Here is an excerpt from Xikar?s web site; ?XIKAR?s Propylene Glycol (PG Solution) maintains 70% RH. Distilled water evaporates quickly and creates humidification fluctuations. XIKAR's proprietary mix of PG Solution is calculated to match the water absorption rate with the rate at which PG biodegrades, resulting in a humidor that will not over saturate with PG. Always maintain 70% RH for the best results.? If you just add distilled water, the crystals will add moisture to your humidor as they dry and then absorb moisture from the air as they dry out. The PG solution is the key. Use the correct size recommended for the size of your humidor (50, 100, 250), not the number of cigars you actually have in your humidor. This unit is for a small humidor. I have several humidors of varying sizes which I access 1-2 times a week and they maintain RH of 66-68% per a digital hygrometer.13
I have 2 of these for my travel humidors and they are working great. I filled each one and it took about 20 minutes for the crystals to soak up the solution. I check them often and they are keeping my level between 72-75%.Per the directions, DO NOT USE only distilled water. The crystals are specifically designed for use with the solution, not water.11
Have 3-4 of these in medium and large sizes; use in my wooden humidors, and use the Xikar and/or distilled water solution. Keep a weekly log of data but I'm not a fanatic or nerd about it. First one I bought I tested with calibrated hygrometer in a sealed ziplock after filling. Consistent and reliable.No leaking on these as the bottom is sealed, unlike Credo or no-name models. Can use either horizontal or vertical mount.Sorry, you can't just fill and forget; crystals swell and maintain 70% RH well for a week or so if minimal openings. No way it 'dehumidifies' as others claim. Have they checked the air seals on their humidors? Isolate the variables guys!I am happy with these and have the data to prove it.11
