62% RH Level 4 Gram Two-Way Humidity Control Pack - Pack of 200

In this review of the 62% RH Level 4 gram Boost Pack, the bottom line is simple: this bulk retail box is for anyone who needs reliable, food-safe humidity control for small sealed containers. The reviewer found it especially useful for preserving delicate herbs, tea, spices and small amounts of coffee or seeds because the packs maintain a constant 62% relative humidity without adding anything but water vapor. The pack of 200 is aimed at serious home users, small retailers or batch packers who value consistent moisture balance and the included Humidity Indicator Cards for quick replacement checks.

Key Features

• Retail pack of 200: Comes in a display box with each Boost Pack individually overwrapped and an indicator card included for easy inventory and single-use handling.
• 4 gram size: Designed to work effectively with up to 14 grams of product, making it well suited for single-dose pouches and small jars.
• 62% target humidity: Patented two-way humidity control maintains a stable 62% relative humidity level inside a sealed container to protect aroma and texture.
• Food-contact safe materials: The internal solution is glycerin and water so the packs emit only water vapor and are appropriate for pantry items and herbs.
• Indicator card included: A Humidity Indicator Card inside each overwrap shows when a pack should be replaced by changing color, simplifying maintenance.

Who It's For

The Boost Pack is a practical choice for home preservers, small food producers and anyone who stores herbs, medical or culinary, in sealed jars or pouches and needs to protect aroma and moisture. It is also useful for coffee samplers, tea hobbyists, spice blends and seed packets where tiny, controlled humidity matters.

Those who store large bulk bags, very high-volume food manufacturing, or items requiring a humidity setpoint other than 62% should consider a different size or model. This specific 4 gram pack is not intended for containers holding more than about 14 grams of product.
