Boveda Two-Way Humidification System
Patented two-way humidity control continually responds to ambient conditions by adding or removing moisture to maintain ideal climate for instrument preservation - effortlessly! Maintains a constant 40%-50% relative humidity level within your instrument's (closed) case. Zero maintenance required!
Boveda Works Automatically -- There's Nothing Else to Add
No more hydrating sponges, hoses, discs, or whatever else you've tried (and dried out) in the past. Boveda eliminates the hassle of these one-way humidification methods which spike humidity when you add water then take a nosedive as the water evaporates.
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.
