Detail 01
Ukulele-specific sizing
Matched to the smaller air volume of a uke case, so it won't over-saturate a small space or crowd the instrument.

OasisOH-18 Ukulele Humidifier
Independent shopping perspective
The Korena take
A humidifier sized for ukulele cases. For anyone with a solid-wood uke stored in dry indoor air.
Strong match
Who this is for
- Solid-wood ukuleles kept in a case or gig bag
- Small cases where a guitar humidifier is oversized
- Dry winter months with heating running constantly
Consider the trade-offs
When to look elsewhere
- Guitar cases — the OH-14 covers that volume
- Laminate ukuleles that move little with humidity
- Anyone who wants a humidity reading included
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Case humidifier, not soundhole-mounted
Moisture reaches the whole body and neck evenly rather than concentrating under the soundhole.
Detail 03
No hygrometer
You refill on feel or schedule. Pair it with a small hygrometer if you want to hold a target range.
Detail 04
$24.95
Costs a fraction of a crack repair or a reset on a small solid-wood instrument.
Detail 05
Oasis OH-18
The small-case sibling to the OH-14. Buying the guitar version for a uke case means a poor fit.
Final check
Know before you order
- 01Hygrometer sold separately if you want an actual humidity number
- 02Only effective with the case closed; a uke on a wall hanger stays dry
- 03Check clearance in a thin gig bag before assuming it fits
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit a soprano ukulele case?
It's built for ukulele cases, so soprano through tenor cases are the intended fit. Slim gig bags are tighter — check clearance.
02Can I use the guitar OH-14 in a uke case instead?
It's sized for a much larger case. The OH-18 is matched to the smaller volume.
03Does my laminate uke need this?
Less so. Laminate is far more stable in dry air. Solid-wood tops and bodies are the ones that crack.
04Does it include a hygrometer?
No, just the humidifier. Add a small hygrometer if you want to track case humidity rather than refill on a schedule.
