Detail 01
Humid-i-Bar sponge
The patented sponge holds more water than competing humidifier sponges, reducing rehydration and checking frequency.

Independent shopping perspective
The Humitar is an acoustic-guitar humidifier that sits between the strings at the sound hole and releases moisture into the instrument. Its Humid-i-Bar sponge is soaked in distilled water, returned to the holder, and checked through the removable top; re-soak it when it is dry. By supplying moisture evenly through the sound hole, it is designed to help guard against warping, shrinking, and cracking. The sponge’s higher water capacity means less frequent rehydration and monitoring than competing sponges.
