About This Item

2-Way Humidification System

Boveda's 2-way humidity control technology automatically protects your instrument against warping, cracks and other damage caused by lack of humidification or too much humidification. Boveda is the only true 2-way humidity control that will add or remove moisture as needed to maintain a constant 45%-55% relative humidity level - the ideal climate for wooden instruments.

Each Boveda consists of a specially prepared saturated solution of pure water and natural salts. This saturated solution is contained within a water-vapor permeable "reverse osmosis" membrane. Boveda works on the scientific principle that certain salts mixed with water will naturally regulate humidity. Boveda's patents are on the methods invented to make this scientific principle portable and practical for the rigors of packaging applications. Boveda absorbs and emits only purified water vapor through its semipermeable membrane and does not damage material through direct contact.

Note: While Boveda’s Packaging specifies that the Wood Instrument 2-Way Humidity Control Kit is for violin, cello, and double bass, among other wooden instruments, we recommend the larger Guitar 2-Way Humidity Control Kit as a more effective alternative for Cello and Double Bass. Both kits include the same 70-gram 49% RH Boveda Humidification Packets, which can also be purchased separately here.

Asked On: 04/19/2020

When one pouch is being used, what is the best method to keep the unused pouch from being "activated"? Thank you

SHAR Answer:

Hi Joanna, thanks for your question! It's best to keep packets inside their plastic packaging until you're ready to use them. Then, when you're ready to use them you can unpackage the packet, place it in the pouch holder, and put the holder inside your case. Hope this helps!

How long does one Boveda pouch last?

SHAR Answer:

Hello Elizabeth! Boveda pouches can last from 2 to 6 months, depending on the climate they're kept in and how hard they have to work to regulate case humidity. When the pouch is hard and dry, you'll know it's time for a replacement! Please let us know if you have any other questions.
