MusicNomad’s HumitarTM uses a special “Humid-I Bar” insert, claimed to hold 2-3 times more water than the competition and has anti drip properties engineered into it, proving more effective than the typical cellulose sponge material. The Humitar is used by placing it between the strings so it may hang down into the sound hole of the guitar safely releasing moisture.
Maintenance of the Humitar includes flipping the top to inspect it for remaining moisture. If it’s dry, a user need on only rehydrate the Humid-i-bar with distilled water. Retail price: $13.99 - $14.99.
