D'Addario Humidipak

Your Guitar Still Thinks It's A Tree. Hydrate It.

Keeping your instrument safe and playable has never been easier, thanks to D'Addario Humidipak. Using Boveda’s two-way humidity control technology, Humidipak automatically adds or removes moisture to maintain an ideal humidity level of 45%-50% RH inside your instrument case.

Hydration For Your Guitar

Two-way humidification maintains a constant 45%-50% relative humidity level within the instrument's case by automatically dispensing or absorbing purified water vapor as needed.

John Oates

"I love the D'Addario Humidipak, especially when touring in dry environments like hotels and airplanes."
Pat Metheny

"Playing hundreds of concerts a year requires pro-level consistency from all the gear that I use. I know I can count on the Humidipak Automatic Humidity Control System."

What is the #1 cause of all instrument repairs?

Lack of humidity is the leading cause of all instrument repairs. It is essential to humidify all wooden instruments

How do I recognize symptoms of a dry instrument?

A dry instrument can be recognized by a number of symptoms. Sharp fret ends, neck bow, sunken top, lifted bridge, lower string height, notes starting to buzz, cracking of the neck and/or body, or change in tone of the instrument.

Which Humidipak do I need?

If your instrument is not already too dry, Humidipak Maintain will maintain a constant relative humidity level inside your case. If your instrument is dry and needs to first be brought back to the proper relative humidity level, use Humidipak Restore

How often should I replace my Humidipak?

Humidipaks typically last between two to six months for an instrument that is already preconditioned to 45%-50% relative humidity. They should be replaced when the packets begin to feel hard or every six months maximum, whichever comes first

What temperature should I keep the room my instrument is stored in?

It's important to maintain a consistent temperature in the room where your instruments are stored. Anywhere in the range of 70-76 degrees Fahrenheit is ideal

Customers have mixed opinions about the value of the product. Some find it worth the money for a higher-end guitar, and affordable. They also say it's simple, effective, and cheap over the long run.

"...Other than that, highly recommended and well worth your money to protect your guitars." Read more

50 customers mention22 positive28 negative

Customers are mixed about the durability of the product. Some mention that it lasts 3-6 months, is very low maintenance, and is easy to maintain. However, others say that it is cumbersome, not long-lasting, and in of itself not reliable. Some say that the packs can wear out pretty quick, and the meter broke within a month.

"...I'd love to save a few bucks and reuse the pouches, but they rip every time...." Read more

"...$ outlay is higher than most, but once purchased, the product is easily maintained and rechargeable...." Read more

"...They lasted for approximately 6 months. As advertised.For the cost, I wish they lasted longer...." Read more

40 customers mention22 positive18 negative

Customers are mixed about the hydration of the product. Some mention it works very well and creates no mess or danger of water leakage. However, others say that the packs do dry out and run dry in just a couple weeks. They also say that they just don't pump out enough moisture.

"...The beauty of this product is its ability to absorb or emit moisture depending on ambient conditions...." Read more

"...Then we had an unusually cold winter and it started losing water and shrinking until I could start to feel the little hard granules forming...." Read more

"...BTW - There is no water added to the bags. They will absorb moisture when humidity is too high and release moisture when humidity is too low...." Read more

"...But if you are in a humid environment the pack can only absorb so much moisture...." Read more

26 customers mention4 positive22 negative

Customers are dissatisfied with the fit of the product. They mention that it doesn't fit in the sound hole, it doesn’t fit smaller guitars, and the pouches are too wide for proper fit. They also say the pouch is too tall and the packets barely fit into the canvas holders.

"...Not the perfect fit for my form-fitting solid body electric case, but plenty of room in the standard issue semi- and hollow body cases...." Read more

"...The hanging hard plastic piece of the pouch is very long and rests against the edge of the sound-hole on one side and the fretboard on the other...." Read more

"...Also, the plastic thing is too long, so if I close the case the plastic thing not only rubs on the fretboard, it rubs on the area between the sound..." Read more

"...Edit: The reason I say it doesn't fit the sound hole very well is because the pouch hangs too low and rests on the back of the guitar...." Read more

2-Way Humidity Control for Your Guitar

Reviewed in the United States on March 10, 2024

Size: KitStyle: MaintainVerified Purchase

No matter where you live, your guitar(s) need to be treated with respect. You shouldn’t leave them exposed to significant changes in temperature and humidity. Don’t leave your guitar in your car/truck/van unless you’re headed to a gig, jam session, or lesson! Don’t leave your guitar leaning against a wall or furniture when you’re not holding it - use a proper guitar stand for TEMPORARY breaks in the music. Storing your guitar in its case, when not practicing/performing, will help protect your beloved axe. (NOTE: Keep your guitar’s hard case closed all the time, except when removing the guitar or storing it after practice, etc.)

Controlling the environment in your guitar’s case is IMPORTANT, too! A hard case is best because it can also be easier to control the atmosphere your guitar lives in.

I use these humidity (restoration or maintenance) packs all the time in my guitar hard cases. I live in the subtropical Gulf Coast region of SE Texas.

You might ask, “Why do you put humidification products in your guitar cases when you live in a humid environment? That doesn’t make sense and it sounds like a waste of money.”

It DOES sound squirrelly, doesn’t it?

Well, this product works TWO (2) WAYS to maintain the correct humidity level for your guitar! It can release OR absorb moisture inside your guitar hard case, keeping the headstock, neck, fretboard, top, bottom, and sides at optimal humidification.

How often you have to replace the packs depends upon the climate and weather your guitar lives/works in and how you store it. Taking care of all that wood (and don’t forget the electrical components if your axe has ‘em) by preventing or mitigating cracks, swelling, joints and glued parts separating, etc., will help extend the life of your guitar and keep the coveted sustain and resonance going.

Great product! I will continue using this company’s humidification products, for as long as I have guitars to take care of, so I can enjoy fingerpicking, strumming, and shredding.

Reviewed in the United States on February 13, 2024

I had a guitar tech tell me to buy these and put them in my Martin acoustic guitar to help the slight bowing of the face of the guitar. It worked. I've been using them for a few years now and they seem to do the job. I purchased a set for my mom's classical guitars as well. So easy to use. The only criticism I have is that the pouch that goes in the sound hole always rips. I'd love to save a few bucks and reuse the pouches, but they rip every time. I'm not rough with them, but pulling the piece out of the sound hole every day eventually rips the pockets that hold the humidifier bags. Other than that, highly recommended and well worth your money to protect your guitars.

A test shows this works

Reviewed in the United States on February 15, 2018

Size: KitStyle: MaintainVerified Purchase

This Humidification System is effective. However, I should give this NO stars for goofing around too much: this is the sixth revision of the Humipak, according to my luthier. The previous revision was total disaster. I bought one, and could not reinstall the bag of humidifying resin on the spine (like a report cover spine.) And I was not alone in this, even the luthier said he couldn't and he's a strong guy and I'm a senior citizen woman. So it wasn't just me. So IF YOU HAD the previous rev with the spine you slid (maybe, maybe not) across the bag, this is NOT like that anymore.

The new revision has saddlebags attached by a ribbon handle. You slip the humipak inside the bags, no closure and stuff it inside your soundhole. (It barely fits in mine, I have a classical guitar. (An acoustic steel guitar will fit it better, they tend to have larger soundholes.) There is a third bag for the headstock area of your guitar case.

Does it work? Yeah it works.I know it works because I ran a test to see if it works (once an engineer, always an engineer.) And it works better than the sponge-type containers that you moisten (daily) and put in the soundhole. Those do not diffuse the water evenly into the guitar body. I know this because my guitar got overly dry EVEN WITH constant use of that device. I ended up taking it in for repair and rehumidification and meanwhile, the second guitar at home was given this new humidifier (because you need a spare, you can see why: the one is at the shop and you're playing the other.)

I ran an experiment on the humidification. I purchased a D'Addario Humiditrak - Bluetooth Humidity and Temperature Sensor to track the rehumification and steamed up my office at home with a cool mist humidifier going 24/7. While the Humiditrak is not a super sensitive device, I'm told it's within 3% and it tracked an immediate increase in humidity. The sponge device stayed at a much lower level of humidification. The guitar got up to 45% humidity and then started to drop again when I turned off the humidifier in the room, so now I know:

1. Use the Humidipak
2. Humidify the room you keep the guitar in, and play in constantly. I use a cool mist humidifer. Distilled water will keep the white dust down, or use the kind that has a filter to remove salts in water.
3. keep case closed and keep guitar in case UNLESS playing it.
4. track humidity and temperature
5. check packs for "crunchiness." Crunchy means it's dehydrated. You need to buy Planet Waves Humidipak replacements. Not cheap (there is some lore about rehydrating in a wet sponge equipped sealed plasticware tub with the old packs on the side not touching the sponge, but I have not tried this. You can find this method here and there on the internet. A pro guitarist friend of mine does it. If I were to try it, I'd run my humidification level check again because even though it might feel soft again (swollen with water) the humidification might not be effective. Stay tuned.

One star off for bad designers who thought that last version was usable. Wow. Just wow. But this version is good and it is effective. I have proof.

It actually works, and works very well.

Reviewed in the United States on January 1, 2024

Size: KitStyle: MaintainVerified Purchase

I bought a new Martin acoustic, only to find out that you need to be mindful of low humidity, and here I live in Las Vegas. It's so dry that I have to run a humidifier in my bedroom every night.

I picked up this 4 pack of temp/humidity monitors and I keep on inside the case using this humidifier. (I verified that they all read the same). The other 3 are outside the case around the house. Every time I open the guitar case the monitor reads 45% humidity. Perfect.

One other thing, Martins also need a bit of care about temperature changes, so I make sure the room is not too cold or hot before opening the case, using the 4 monitors I bought. 70 degrees is easy to maintain inside and outside the case, day and night.
