Boveda 49% High-Absorbency Guitar Humidifier, 4-Pack - For Humid Climates — Open-Box, 32% Off

HOW HIGH-ABSORBENCY BOVEDA WORKS FOR MUSICAL INSTRUMENTS: ABSORBS 3X MORE MOISTURE than Boveda 49% RH! Stabilizes the humidity within the ideal range—45–55% RH, even in extreme humidity. If the air inside a case is too moist, Boveda absorbs that moisture. If it's too dry, Boveda releases small amounts of water vapor into the case. Wide humidity fluctuations will cause the wood to expand or shrink, which puts stress on the instrument & degrades its performance abilities.

CHOOSE BOVEDA: Trusted by over 3 million people to protect & maintain items at the perfect humidity level. Boveda's the only patented 2-way humidity control solution with 25 years of experience. Using saltwater in our humidity packs, we provide the fastest, most precise humidity control in the market for wood instruments. When you invest in an instrument, you want to ensure you take care of it to produce optimal sound. Boveda is the only humidity solution that can do so within 24-48 hours.

HOW TO USE: Always insert Boveda packs into a protective Boveda Fabric Holder before using in an instrument case. Boveda Fabric Holders are available separately & in Boveda Starter Kits. Remove a pack from the resealable bag. DO NOT cut or open the brown humidity packet. Slip the packet into the holder. Place in case and close the lid. BOVEDA DOES THE REST. When High-Absorbency Boveda 49% RH puffs up, it’s time to replace the pack. NEVER MIX the 49% HA with any other %RH.

WHO IS HIGH-ABSORBENCY BOVEDA FOR: Musicians who live in year-round extreme humidity who struggle to maintain the right RH for instrument storage use Boveda HA 49 for acoustic & electric GUITARS, WOODWINDS & BOWED INSTRUMENTS. Professional musicians, band & orchestra leaders, instrument techs, music teachers, hobbyists & student musicians use Boveda packs for easy & precise humidity management in instrument cases. NO DAILY MAINTENANCE! WHY RISK A WARPED OR CRACKED INSTRUMENT OR MUSTY CASE?

Love Your Instrument—for effortless humidity protection, use Boveda. Having been in the industry for 25 years, Boveda is a trusted and experienced brand in relative humidity control. But what does that even mean? Relative humidity (RH) refers to the percentage of humidity within an environment. In other words, it answers the question, 'how moist or dry is the air in my instrument case?' Boveda's founders & scientists discovered that the right RH has a huge impact on a wood instrument's performance & sound & safeguarding its construction. Using Boveda, you'll maintain a precise moisture level between 45 and 55% RH—no more mustiness in your instrument case. USE BOVEDA HIGH-ABSORBENCY HUMIDIFIER/DEHUMIDIFIER PACKS FOR A WOOD INSTRUMENT EXPOSED TO HIGH HUMIDITY YEAR-ROUND. Just slip a Boveda into a Fabric Holder (available separately), position it in your case & forget about the pack until it expands. Once it does, just switch it out with a replacement pack. (Unlike Boveda 49% RH humidity packs, HIGH-ABSORBENCY BOVEDA PACKS DO NOT GET HARD OR CRUNCHY WHEN YOU NEED TO REPLACE THEM.) Each Boveda High-Absorbency 49 pack will last 1 to 6 months. Its lifespan depends on how often you open your case, how airtight your case is, & how dry or humid the climate you live in is. Maintain the right humidity in a musical instrument case for: GUITARS, including acoustic, electric, electric bass, guitarrón, hollow-body, nylon string & semi-hollow body; FRETTED INSTRUMENTS, including banjo, mandolin & ukulele; STRINGS, including cello/violoncello, double bass/upright bass, hollow-body bass, viola & violin; & WOODWINDS, including bass clarinet, bassoon, clarinet & oboe.
