BOVEDA B49HA Humid Climate Refills

For wooden instruments. 

Also for guitars. 

Exclusively for musicians who live in or travel to extremely humid climates.

Replace your High-Absorbency Boveda every three (3) months.

Just slip these refills into Boveda Leakproof Holder(s) and slide them back into your instrument case.

Automatically maintains constant RH between 40% and 60% for instruments in high humidity climates

Prevents warping and mildew build-up

Curbs humidity fluctuations that throw off an instrument's measured alignment and cause permanent damage (think going in and out of air-conditioned venues, traveling by air, performing outdoors, etc.)

Always insert Boveda into a leakproof holder before using in your instrument case.

The holder acts as a liquid barrier if a packet is accidentally punctured while extending the life of your Boveda packets.

The patented interior material allows water vapor to pass through to your instrument. The exterior is soft, like a polishing cloth, so it doesn’t scratch the finish.

Don not mix B49HA and B49 or different Boveda RH levels  within the same instrument case. 

Do not use other humidification products with Boveda in the same case because they will fight against each other and reduce the efficiency of Boveda.
