  • One (1) Single (1-Pouch) Boveda Holder
  • Three (3) Boveda Refill Packets
  • Step-by-Step Instructions

HOW TO USE:

BEFORE USING BOVEDA:

  • ALWAYS insert Boveda into a holder before using in your instrument case. The holder acts as a liquid barrier if a packet is accidentally punctured and extends 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 your instrument. 
  • DO NOT mix different Boveda RH levels including Boveda B49HA 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.

STEP-BY-STEP INSTRUCTIONS:
  1. Remove the clear overwrap from the packet. (DO NOT OPEN the Boveda itself.)
  2. Insert one (1) unwrapped Boveda into each pouch of each holder.
  3. Place in the case anywhere that allows for airflow and prevents puncture when you close the case.
  4. Close the case's lid. Always keep your instrument case closed when using Boveda.

PLACEMENT IDEAS:

Double holder:
  • Into the sound hole
  • Over the strings
  • ­Open area in the case

Single holder:
  • Under the neck or headstock
  • On the strings
  • Under the tailpiece
  • Open area in the case

PACKAGING:

Each Boveda in these kits is individually overwrapped. An unopened Boveda is good for up to two (2) years.

LIFESPAN:

Replace Boveda 2-way humidity packets every three (3) months.

ACCURACY:

Achieves and maintains a constant relative humidity (RH) range between 40% and 60%, the industry standard for wooden instruments.

    Works great!!

    Great product! Easy to use, no mess, way better than traditional water/sponge humidifiers. Works great with my Martin OMC and my Fender Acoustasonic! Ordering again soon.

    18% Humidity.... Boveda To The Rescue!

    This has been a brutally cold winter in my neck of the woods (North East, Ohio). We relied heavily on our wood stove to keep us warm for the past two months, but wood heat, though economical and warm, dries the heck out of the air. I had humidity readings at times, below 20%. Thank goodness every one of my guitars was equipped with a Boveda humidity kit. They weren't able to consistently maintain 49% humidity in the cases given the ridiculously dry, outside air, but they at least kept my instruments out of the danger zone. I will always rely on Boveda throughout the year, to maintain a safe climate within the cases of my prized instruments. The few bucks spent on fresh humidity packs is peanuts compared to the damage that can occur during excessively dry or wet times of year.

    Arrived intact and as described. Still very early to rate the performance but I trust that it will do what it is designed to do. Thank you.
