Forget about warped and moldy reeds. This 72% RH Humidifier Pack will keep your reeds in perfect, ready-to-use shape between practice sessions. Its two-way humidity control keeps your reeds at a constant 72% humidity, so if your environment is too humid, it will will remove humidity, and if it's too dry, it'll add it back, automatically. Imagine putting a reed on, and having it be ready to go! Just put this pack, along with your regular-rotation reeds, in a heavyweight zipper bag and presto — you've got a humidity-controlled environment for up to 4 months! Comes in a sealed pouch for freshness. How does it work? Read on for the pseudo-science: 2-way humidity control works by continually responding and adjusting to ambient temperature and humidity by either adding or removing moisture to regulate a pre-determined Rh (relative humidity). The control device must change behavior as shifting conditions require. For instance, 2-way moisture control responds to shifting ambient conditions to provide only the right amount of moisture. There are numerous commercial products on the market that only provide 1-way control, meaning they'll give off moisture (humidifier) or absorb moisture (desiccant). Neither of them have the ability to regulate. A humidifier (sponge, gel, beads, crystals, silica, wet paper towels) all add moisture to a container, even if it's already too high. A desiccant removes all moisture. Those conditions are damaging unless you need very high humidity or none at all. These pouches are based on the scientific principle that certain salts mixed with water will naturally regulate a specific Rh. And there you have it. Your reeds don't care; they'll just be happy.
