Boveda packets preserve your stored herbs, flowers & botanicals by maintaining 62% RH in a sealed environment. Each packet consists of a specially prepared saturated solution of water and salt which continually responds to the climate by adding or removing moisture to maintain a 62% RH level.

Boveda will never humidify beyond the RH level on the packet, so there is no such thing as “too much”. The more that is used, the more efficient Boveda will work and the longer it will last. No activation or maintenance is required and it lasts months in a sealed container. Replace when packet becomes rigid.

Features:

• Two-way humidity control maintains 62% RH with a ±1% accuracy
• Reaches desired humidity within 24-48 hours
• Lasts 2-4 months in an airtight container
• FDA approved, environmentally friendly & biodegradable
