Using these Boveda humidifier replacement packs is easy. Just place them in your instrument case when it's time to replace the old ones. There's no need for any maintenance, so you don't have to worry about filling hoses or wetting sponges. Keep in mind that these packs are designed to maintain a relative humidity between 45% and 55%. Avoid exposing your instrument to extreme humidity swings outside of this range, as it can damage the instrument. For long - term use, check the packs regularly to see if they need replacement. If you notice that the humidity in your instrument case is not within the ideal range, it might be time to get new packs.
