My Guitar Collection and Humidity Control
I'm a guitarist with a modest collection: a couple of Martins, a Recording King, and an older Yamaha acoustic. Maintaining proper humidity is crucial for these instruments. For years, I've relied on D'Addario Humidipaks to keep the humidity levels between 40% and 50%, specifically around 45-50%. They’ve done a great job, but I recently realized it was time for a change.
The old Humidipaks were getting hard, a clear sign they needed replacing. Consistent humidity is essential for preventing cracks and warping in the wood. This is why I decided to try a different option.
Introducing Boveda Humidifiers
I decided to try Boveda humidifiers. I purchased a large 12-pack, which is enough for three sets of humidifiers (one for the headstock, two for the body) across my guitars. Boveda actually manufactures D'Addario's Humidipaks, meaning they are essentially the same product. The package recommends 49% relative humidity for wood instruments.
These humidifiers come individually packaged, unlike some other options. It is important to note that for first-time users, it's recommended to buy the starter pack with the cloth pouches. This provides better protection and distribution of humidity within the guitar case.
Ease of Use and Performance
I'm using my existing D'Addario pouches, placing three Boveda packs in each. The packs feel noticeably softer and more pliable than the older D'Addario packs, indicating they're still fresh and effective in maintaining humidity. Their consistency suggests that they should perform as expected.

Changing these out is simple – when they become hard, it’s time for a replacement. Both Boveda and D'Addario offer excellent options for maintaining humidity in acoustic guitars and other wood instruments.
Comparison: Boveda vs. D'Addario
Both Boveda and D'Addario Humidipaks effectively maintain humidity around 45-50%, ensuring optimal conditions for your instrument. From my experience, Boveda's large packs offer a cost-effective alternative. While they are essentially the same, the packaging and pack size differ.
The choice between them is largely personal preference and budget. I've been primarily using D'Addario bags for years, and now I wanted to give Boveda's a try.
Placement and Additional Tips
The standard D'Addario three-bag system works well with Boveda packs. You will need two pouches for the body, one each side of the sound hole, and one for the headstock. The packs are easily inserted into the cloth bags, offering a more even distribution of humidity compared to directly placing the packs in the guitar case.

While some rehydrate the pouches, I've never found it necessary. The key is simply replacing them when they become hard to maintain ideal humidity levels.
Conclusion and Recommendation
Both Boveda and D'Addario offer reliable humidity control for your acoustic guitars. Boveda offers a more economical option in terms of bulk buying, while D'Addario is a trusted brand known for its quality. The performance of both is nearly identical as they’re made by the same company. Choosing between them comes down to personal preference and the size of your guitar collection.

I highly recommend using a humidity control system to protect your valuable instruments. Maintaining proper humidity prevents damage from cracking and warping, extending the life of your guitars. Both brands are solid choices; choose the one that best suits your budget and needs.
