This is the humidifier that we suggest to anyone getting a solid wood ukulele that lives in an extremely dry climate, or has periods of the year that get very dry, as in under 30% humidity. It is more effective than any other humidifier we have found and is made specially for any size ukulele.
The mounting system allows the humidifier to hang horizontally inside the ukulele rather than vertical (like the guitar humidifier).
Secondly, the humidity output is about 50% of the Royal Blue Oasis guitar humidifier, to accommodate the smaller instrument size. This also allows the humidifier to last twice as long between refills.
Hand-crafted in America, Oasis is the best solution to the challenge of ukulele humidification. You have made a significant investment in a quality instrument and it is important to protect that. It is far less expensive to have an effective, easy to use guitar humidifier than it is to repair a cracked instrument. Give Oasis a try and you will see how well it works!
