1. Introduction and Product Overview
Boveda 62% RH Two-Way Humidity Control Packs are designed to maintain a precise relative humidity level within an enclosed container. These packs are ideal for storing items that benefit from stable moisture conditions, such as herbs, tobacco, and other sensitive products. The two-way humidity control technology either releases or absorbs moisture to achieve and maintain the target 62% RH, ensuring optimal freshness and preventing items from becoming too dry or too moist.
This manual provides instructions for the Size 8-10 packs, which are suitable for storing up to 1 ounce (28 grams) of product.

2. Setup and Initial Use
Using Boveda humidity packs is a straightforward process. Follow these steps to prepare your storage environment:
- Remove from Packaging: Take one Boveda moisture pack from its resealable bag. Ensure the remaining packs are sealed tightly in their original bag to preserve their lifespan.
- Placement: Place the Boveda pack directly into your airtight storage container. Do not cut or open the brown humidity packet itself.
- Add Items: Fill the container with your items, ensuring there is enough space for the Boveda pack to function effectively.
- Seal Container: Close the container securely to create an airtight seal. The Boveda pack will then begin to regulate the humidity.

3. Operating Principles
Boveda's two-way humidity control technology works by creating a monolayer of purified water molecules. These molecules naturally coat the trichomes of your stored items, preventing the evaporation of terpenes and preserving their quality.
The pack continuously monitors the ambient humidity inside your airtight container. If the air is too moist, the Boveda pack absorbs excess moisture. If the air is too dry, it releases purified water vapor to rehydrate your items. This dynamic process ensures a stable and precise 62% RH environment, protecting your products from fluctuations that can degrade their quality.

4. Choosing the Right Size and RH Level
Boveda offers various sizes and RH levels to suit different needs. The 62% RH level is specifically recommended for items that benefit from being stickier, fluffier, and bouncier, or for restoring overly dry items to their original state. It is also suitable for users in low-humidity climates.
Size 8 packs are designed to protect up to 1 ounce (28 grams) of product. For larger quantities or different container types, other Boveda sizes are available.
- 58% RH: Recommended for humid climates or less sticky items, facilitating easier grinding. Suitable for long or short-term storage.
- 62% RH: Ideal for stickier, fluffier, bouncier items, restoring dry items, and preventing staleness. Suitable for long or short-term storage.

5. Maintenance
Boveda packs are designed for long-lasting performance. To ensure continuous optimal humidity control, it is important to replace them periodically.
- Replacement Schedule: Replace Boveda packs approximately every 3 months, or as needed.
- Indicator: You will know it is time to replace a Boveda pack when it becomes hard and crunchy. A fresh pack will feel soft and pliable.
- Do Not Mix: Never mix Boveda packs of different RH percentages within the same container, as this can interfere with their ability to maintain a stable environment.
6. Troubleshooting
While Boveda packs are highly reliable, ensuring proper usage is key to preventing common issues:
- Inconsistent Humidity: Ensure your storage container is truly airtight. Leaks can prevent the Boveda pack from effectively regulating humidity.
- Packs Hardening Quickly: If packs harden much faster than 3 months, it may indicate that your container is not airtight, or the ambient environment is extremely dry, causing the pack to work harder. Check your container's seal.
- Packs Not Softening Dry Items: For very dry items, it may take several days or even a week for the Boveda pack to fully rehydrate them. Patience is key.
