Boveda's patented 2-way humidity control continually responds to ambient conditions by adding or removing moisture to affect the enclosed environment and deliver the pre-determined relative humidity, keeping the contents of your containers at the perfect desired level. The hyper-filtration membrane inhibits the passage of any impurities, ensuring that your products are exposed to only clean, pure water vapor.
All Boveda products are maintenance free and require no action, just place them in an airtight container with your items, and the Boveda technology will do the rest. Your material will stay fresh, with stable moisture content, delivering a consistently exquisite experience every time. Boveda Humidity Packs will last two to six months, depending on conditions. Simply replace the pack when it becomes rigid.
