Boveda 4 pack 49 RH humidity control
Pack of 4 replacement units for the Boveda humidity control system. Boveda is a maintenance free 2-way humidity control for fretted, bowed and wood woodwind instruments, including: acoustic guitars, classical guitars, flamenco guitars, basses, guitarróns, violoncellos, double basses, bass clarinets, bassoons, and large cases. Boveda creates the perfect humidity balance for your wood instrument whatever the humidity level of your environment. Boveda automatically humidifies and dehumidifies—whatever your instrument’s surroundings call for. Without foams, hoses and sponges that require constant attention and could damage an instrument, affect the sound and playability and lead to costly repairs, Boveda achieves and maintains a constant relative humidity (RH) range of 45% to 55%—the safe zone for wood instruments. No maintenance for months! Initially, Boveda has some catch-up work to do, so your first Boveda won't last as long as subsequent ones. After your first set, Boveda will last 2-6 months depending on the time of year, your climate and your case. Replace when rigid.
