Maintaining your instrument's humidity level is essential to preserve its playability, sound, and integrity. D'Addario's Small Instrument Humidifier easily fits in smaller cases and releases moisture evenly and slowly to maintain the proper humidity level preventing cracks, warping, and shrinkage to your instrument. Using the humidifier is as easy as moistening the sponge when it becomes dry. The humidifier can also be used in conjunction with the D'Addario Soundhole humidifier (GH) for acoustic guitar cases when your humidity is consistently 20% or lower.

  • Ideal for keeping smaller acoustic, bowed and woodwind instruments at the proper humidity level
  • Small size fits in any case
  • Releases moisture slowly and evenly
  • Sponge style humidifier
  • Safe for all instruments


A sponge humidifier can last anywhere from a couple of days to a couple of weeks before it needs to be refilled. It is always best to use a hygrometer along with a humidifier so that you know the exact humidity level inside your guitar case. A guitar should be stored between 40% - 60% RH. If the humidity level of your guitar case is above 60%, discontinue use and contact us. D’Addario offers a standard hygrometer and a smart hygrometer call Humiditrak.

Here are some tips to prolong the life of your Sponge Humidifier:

1. Never store your instrument near a heating element such as a radiator, forced air heating vent, etc., and try to keep out of direct sunlight (through windows) for an extended period of time. 
2. Use distilled water! Tap water has minerals, etc. that can compromise the effectiveness of the foam and oxidize the hardware of your instrument. Filtered water can be used as well.
3. We highly recommend getting a hygrometer to monitor humidity level inside your instrument case.


Two-way humidity control works by continually responding to the outside temperature and climate by adding or removing humidity as needed to maintain a relative humidity inside the Reed Vitalizer bag.
