The Humidi-Cure 62% Control Pack from ATMOSIScience delivers accurate, two-way humidity regulation at a consistent 62% RH without liquids or salts. By simply placing the pack inside a sealed container, it automatically balances moisture by absorbing or releasing moisture when needed, within a ±2% precision. Just like the Humidi-Cure Plus and Humidity Control Liner D52, the Humidi-Cure 62% Control Pack is built with patented fiber-based technology that is 100% biodegradable and helps prevent mold while protecting freshness. Each packs last up to 120 days and provides a leak-proof solution that doesn’t contaminate the contents, maintaining premium quality from curing through consumption.
