Detail 01
Case humidifier, not soundhole
Sits in the case rather than hanging between the strings, so nothing rests against the top or the finish.

Independent shopping perspective
The Korena take
Basic case humidifier for acoustic instruments stored in a closed case. Cheapest way to keep a solid-wood top from drying out.
Strong match
Who this is for
- Solid-wood acoustics stored in a case through winter heating season
- A first humidifier for someone in a dry climate
- Adding humidity to a second or third case cheaply
Consider the trade-offs
When to look elsewhere
- Anyone who wants to verify humidity levels — no meter included
- Instruments left out on a stand where a case humidifier can't work
- Laminate-body instruments that don't need humidity control
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
Gel-based
Water is held in gel and released as vapor, which reduces the chance of a drip landing on the instrument.
Detail 03
Refillable
The gel is replaceable, so the unit keeps working for seasons instead of being thrown out when output drops.
Detail 04
Under $25
Low enough that outfitting several cases costs less than repairing one dried-out top.
Final check
Know before you order
- 01No hygrometer included — you are humidifying without a reading
- 02Use distilled water; tap water minerals shorten gel life
- 03Only works in a closed case; an open case loses the moisture immediately
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this come with a hygrometer?
No. It humidifies but does not measure. Pair it with a hygrometer if you want to confirm your case is in a safe range.
02How often do I refill it?
Depends on how dry your room is. Check it weekly during heating season and top it up when it feels light or flat.
03Can I use tap water?
Use distilled. Minerals in tap water build up in the gel over time and shorten how long the unit lasts.
04Does it go in the soundhole?
No, this is a case humidifier. It sits in the case, not between the strings.
