Boveda Humidification Starter Kit (Large)

Boveda technology is unlike all other 1-way humidifiers, it’s the only true 2-way humidity control that will add or remove moisture as needed to maintain between 45-55% relative humidity in your case. Helps protect your wooden instrument against warping, cracks and other damage caused by lack of humidification or too much humidification. Typically lasts between 2-5 months in a seasoned case. Longevity depends on time of year, case quality and ambient RH levels. Each Boveda consists of a specially prepared saturated solution of pure water and natural salts. This saturated solution is contained within a water-vapor permeable “reverse osmosis” membrane. Boveda provides the cleanest and most purified humidity of all other products available on the market today.
