The Martin Guitar Humidifier is built to protect your acoustic guitar in the simplest and safest way. It is made from high quality non vinyl and non allergenic resin that feels soft and gentle around the soundhole. This soft material prevents pressure on the wood and keeps your guitar safe while still being strong enough to avoid touching the delicate inner parts. Everything about this humidifier is made with careful attention so your guitar stays in great shape through dry seasons.
Inside the tube is a special water suction stem that absorbs ten times its weight in water. This powerful stem holds moisture deeply and releases it slowly through the small holes. Your guitar receives a steady and balanced amount of humidity. This helps stop cracking, shrinking, and other damage caused by dry air. The slow and even release makes it a dependable choice for long practice hours, travel, or storage.
Martin designed this humidifier to stay simple and easy to use. You just soak the stem, place it into the tube, and position it safely in the soundhole. The soft resin tube rests gently so it does not create stress on the wood. Once inside, it works quietly without any mess or dripping. This is great for guitar owners who want protection without constant checking or complicated steps.
Made from non-vinyl, non-allergenic resin, this durable humidifier stays safe for your guitar and players, avoids chemical smells, and provides reliable care year after year.
The humidifier’s stem is another reason it works so well. Because it absorbs so much water, you do not need to refill it too often. It keeps the inside of your guitar hydrated without flooding it. This careful moisture control helps keep your tone warm, rich, and balanced. Many guitar owners notice improvement in sound stability when using a proper humidifier like this.
Martin has also partnered with MusicNomad Equipment Care to bring thoughtful improvements to their guitar care products. Their updated designs show how serious Martin is about helping players maintain their instruments with simple, safe tools. Every detail in this humidifier reflects this commitment.
If you want your guitar to last longer, stay smooth, and sound full, this humidifier is a smart choice. It helps prevent costly repairs and keeps your guitar comfortable all year. For acoustic players who value protection and simple care, this is a dependable tool.
The best quality of this humidifier lies in its safe, soft resin that protects your guitar’s wood and its sturdy stem, which holds more water for long-lasting moisture release.
The MusicNomad Humitar Acoustic Guitar Humidifier (MN300) gives your guitar the steady moisture it needs to stay healthy all year. Acoustic guitars are made of wood, and dry air can cause the body to warp, shrink, or even crack. This humidifier makes humidity care simple, safe, and low-maintenance for every guitar owner. It hangs from the strings and sits in the soundhole, so the moisture goes exactly where your guitar needs it most.
This humidifier uses MusicNomad’s Humid-i-Bar sponge, which holds up to ten times its weight in water. Because it stores more water than basic sponges, you don’t have to check it every day. It releases moisture slowly and evenly, helping your guitar stay stable in dry seasons without any mess or dripping.
Checking the humidifier is quick and simple. The top flips open so you can touch the sponge to see if it’s wet or dry. If it feels dry, just remove the sponge, soak it in distilled water, and put it back in. It’s easy to rehydrate and ready to use again in seconds. This makes the MN300 a great choice for players who want strong protection with very little effort.
The Humitar protects your guitar’s body by maintaining optimal humidity in the soundhole, helping it stay in tune, sound richer, and last longer, whether on a stand or in a case.

If you want to monitor your guitar’s humidity and temperature, you can attach MusicNomad’s HONE hygrometer (sold separately). It clips into the Humitar in place of the regular lid. This gives you an all-in-one system that humidifies your guitar while letting you see the exact humidity levels.

Each Oasis OH-5 Plus+ comes with a stabilizer bar that helps you mount the humidifier safely in the soundhole. You also get a 10 cc syringe that controls how much distilled water you add.
