The Humitar ONE Acoustic Guitar Humidifier & Hygrometer (MN311) | Humidifier & Hygrometer in One to Protect Your Acoustic Guitar

Works as advertised. In prefer the Humitar ONE over the D'addario and other brands as this unit comes with an accurate hygrometer and a sponge that holds more water and with less chance of leakage in my opinion. I have tried many of these guitar humidifiers and the Humitar ONE is my favorite. I have 7 Taylor acoustic guitars and one hollow body electric, they all have a Humitar ONE.

Nice product and works as expected and described. The hygrometer (humidity gage) pushes it up to a 5 star review. If you have a quality wood guitar, a humidifier such as this is a must. I wouldn't use anything less for my Martin.

I needed a humidifier for my new acoustic. This does the trick. I like the readout for humidity and temp. Very helpful. I thought it was a little expensive but what isn't in 2026.

It's easy to use and built very well. You put this on the strings 3 and 4 and it then applies to the body of the acoustic guitar. I don't like how it stretches the strings. I also don't like how high it protrudes vertically. My case is snug and it comes into contact with the device, causing it to push downward the strings already being stretched horizontally by the device thickness. Just doesn't seem like a good idea to me. But I could be wrong.

Works as expected

I really like that it shows the humidity and it's easily recharged with distilled water.

Fantastic humidifier and easy to use. Flip top makes refills go quick. Well built with long life battery. Seems to be an accurate readout.

Great product at a great price. Works exactly as described. Do to winter and a pellet stove my acoustic was at 25% humidity. After 5 days the sponge was dry but the case humidity was nearly 40% after another week case humidity was over 50%

This humidifier works awesome, I put it in my violin case and I noticed a big difference. My violin stayed more in tune!

他の商品と比較検討しましたが注水＆装着ともベストだと自信から確信に変わりました！

Easily fits in the sound hole & hangs between the A & D strings. The guitar can be stood up on end in its case & this unit doesn't touch it any of the guitar. It also gives temperature as well as humidity. The spongy insert seems to evaporate after only a couple of days, so I have to remember to refill it with distilled water. All in all very useful little gadgets for my 2 solid wood guitars

Ottimo, fa in maniera eccellente il suo lavoro. L'ho messo nella custodia della mia Martin e riesco a tenere sotto controllo l'umidità regolarmente

Lo que me gusto Es fácil de usar, practico, ya cuenta con pila, la pantalla tiene función para marcar a grados centigrados, la esponja de humificacion es de buen material, eso es lo que me gusto Lo que no me gusto Es que no se que tan preciso sea el hidrometro por eso siempre trato en revisar constantemente su grado de humedad, pero la revisión es normal, tanto como dice el fabricante como los especialistas que arreglan y humifican las guitarras Lo recomiendo si apenas estas empezando y quieres cuidar tu guitarra por un presupuesto no tan alto ☺️
