Detail 01
In-soundhole design
Hangs between the strings into the body, so moisture goes where the top and braces are, not the whole case.

OasisOH-1 Original Guitar Humidifier
1/3
Independent shopping perspective
The Korena take
The standard in-soundhole humidifier for acoustic guitars. If you live somewhere dry or heat your home in winter, this is basic protection for the instrument.
Strong match
Who this is for
- Acoustic guitar owners in dry climates or forced-air heated homes
- Protecting a solid-wood top through winter
- Anyone storing a guitar in a case for weeks at a time
Consider the trade-offs
When to look elsewhere
- Solid-body electric players — no acoustic cavity to humidify
- People in already humid climates, where adding moisture causes problems
- Anyone wanting automatic room-level control across multiple instruments
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
$22.95
Cheap relative to a neck reset or a cracked top. This is preventive maintenance, not an accessory upgrade.
Detail 03
OH-1 Original
The base model in Oasis's line. It humidifies but does not include a built-in gauge to show remaining water.
Detail 04
Refillable
You add distilled water yourself and top it off as it empties. Ongoing habit, not install-and-forget.
Final check
Know before you order
- 01Use distilled water only. Tap water leaves mineral deposits and shortens the unit's life.
- 02No hygrometer included — buy one separately to actually know your case humidity.
- 03Check the fill weekly in dry months; an empty humidifier protects nothing.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Do I need this for an electric guitar?
No. It is designed to hang in an acoustic soundhole. Solid-body electrics have no cavity for it and are far less sensitive to humidity swings.
02How often do I refill it?
Depends on how dry your environment is. Check it weekly during heating season and refill when it feels light or flat.
03Can I leave it in while playing?
Take it out before playing. It hangs between the strings and belongs in the guitar while it sits in the case.
04What water should I use?
Distilled water only. Tap and mineral water leave deposits that clog the unit and can shorten how long it lasts.
