Violin Humidifiers

Violin humidifiers are normally inserted into violin cases to assist with the regulation of moisture in the air (or within the case). As wood interacts with moisture constantly, if the air inside a violin case is too dry, it may suck out the moisture from the wood of the violin, altering the instrument's playing capabilities. The opposite may happen when too much moisture is present and the violin wood may absorb the excess moisture, causing swelling. When a violin is exposed to extreme variations for long periods of time, open seams or even cracking may result.

A good humidifier will protect the instrument in cases of both high and low moisture in the air and is a "must" especially in areas where humidity varies greatly.
