Replace Boveda packets every three (3) months. Just slip these refills into the Boveda Holder(s) from your B49HA Starter Kit and slide them back into your case. Set up a subscription to get replacements auto-shipped to you every three (3) months, so there's no lapse in humidity protection.

Boveda 2-way humidifier packages
Ever since I learned about the Boveda humidifier packages I’ve been using them for all my stringed instruments. They give me a piece of mind that the instruments will always be in great shape. They are easy to use and no mess. I highly recommend them.
