Guitar Humidipak Maintain

I've been using the maintain system for years and it works great. I use it in the case of my Breedlove and recommend it to make sure your guitar has no humidity issues/

I replaced my 'Maintain Humidipack' a couple of weeks ago. It has been with my guitar in a closed, solid, case. I have opened it briefly twice to check the humidity level and then closed the case immediately. My hygrometer in the case was reading 59 - 60%. I believe this should be 45-50%. I'm concerned that the humidipack is not regulating the humidity level correctly.

Sadly the Humidipak Maintain did nothing to bring humidity level down from 63 in my guitar case, so I bought Humidipak Absorb in the hope that it would do the job, but it too had zero effect. I am nevertheless expecting that the Humidipak Maintain will be better at boosting humidity in my guitar case when humidity is on the low side. For periods in which humidity is high, I think I am going to have to invest in a dehumidifier to reduce the humidity of the whole room.

Works great

Excellent product use them in all my guitar cases.
worry free protection.

It is a slick system. I'm using 4 paks suspended in 2 of your saddle holders in my D18.

Unfortunately the last shipment I ordered was stolen, but I've been using these for years. I live in the Mojave Desert and I own several high end acoustic guitars. It's critical that I keep them hydrated and these humidipaks do the trick. They're easy to use and effective. My only complaint is the bags that hold them wear out over time and sometimes they're difficult to get the packs into. Other than that I live them.

I reside in a desert environment so these packs are a necessity. They really do the job.

Great!!!

Fantastic system it's all I use over several guitars.

ALWAYS USE THESE AND SO DO THE HIGHEST QUALITY MUSIC SHOPS. SELF ADJUSTING FOR ALL CLIMATES. FOLLOW SIMPLE DIRECTIONS AND DON'T WORRY!!!

Great product.

Jury still out on this item, although things look promising! Humidity is now at 44% in both of my Taylor’s cases.

Price is right - Product works well for what it is designed for. Have been using for about 2 years in all my guitars - No negatives - only positives.

Great, they last a long time and have served me well.

Easy to keep and does his job the best.

Well worth the cost. If your using them in a hard case they have a long life. Depending on the conditions they last me often 5-6 months. I live were the humidity and winters are more moderate so it may be different if you’re living somewhere with more extreme humidity, dry air, etc. still would be worth the piece of mind.

Great product! I have used them for years and they always work great.

Worked as expected.

Guitar Humidipaks work great. Use them for my two Taylor's

Dear Sir/Madam:

Once again my order has been botched by D'Addario.

I just received a UPS email indicating that the package from D'Addario could not be delivered to the address shown. The address D'Addario placed on the shipping label was an address I EXPRESSLY asked in my email of July 20,2026 NOT TO USE. In that email I provided another address to use which was completely ignored.

So here I am nearly a month after I placed this order, and paid for it, with no product after TEN (10) emails sent and received regarding this order!! Secondarily, I am beyond belief that D'Addario has placed such a low priority to making certain I received my order, especially since I paid for this order on July 6th.

At this point I feel there are only two (2) options that I will be satisfied with due to the COMPLETE ABSENSE of even a morsal of good customer service:
1) Send a new order TODAY VIA UPS OR FEDERAL EXPRESS - Next Day Delivery to the address I included in my email of 7/20/2026.

2) Provide me a complete refund of this order IMMEDIATELY. Not tomorrow, not next week, but IMMEDIATELY.

Live in Denver & Summit county Co and wouldn't go anywhere without these super flexible humidity control devices..... I have them in all of our acoustic guitars along with a wifi monitor to keep track of each guitars humidity conditions.
I duy these in the 24 packs

Love the product. Have used them for quite awhile.
I was fortunate enough to be included in the Beta test for a new design. Hopefully the beta design will become the norm.

They are excellent.

Works as advertised.

Nice strings!

Great way to keep guitars like new.
