Boveda 62% Two-Way Humidity Control Packs For Storing 1 lb – Size 67 – 20 Pack – Moisture Absorbers for Storage Containers – Humidifier Packs – Hydration Packets in Resealable Bag

Having been in the industry more than 25 years, Boveda is a trusted and experienced brand in relative humidity control. But what does that even mean? Relative humidity (RH) refers to the percentage of humidity within an environment. In other words, it answers the question, 'how moist or dry is the air?' Boveda's founders & scientists discovered that the right RH has a huge impact on an item's aroma, flavor & construction. Using Boveda, you’ll maintain a precise moisture level, which keeps your natural hand-rolled items fresh. No more mustiness. You can even use a Boveda pack to revive dry items. It takes just seconds to protect your items with Boveda. Use one Size 60 humidifier packet for every 25 TOTAL items your humidifier box can store. Just slip a Boveda in with your hygrometer (hygrometer is optional); close the container; and forget about the pack until it starts to get hard. Once it does, just switch it out with a replacement pack. (This multi-pack of Boveda 65 RH Size 60 contains 20 replacement humidity control packs in a reclosable bag.) Each pack can last you up to 4 months. Its lifespan depends on how often you open the container, how airtight your humdifier box is and how dry or humid the climate you live in is. Just a few hours without 2-way humidity control can affect the flavor & character of hand-rolled premiums.
