  1. Music Nomad MN300 Humitar Acoustic Guitar Humidifier

Music Nomad MN300 Humitar Acoustic Guitar Humidifier

Pros

  • Durable/Long Lasting
  • Anti-drip Material
  • Low Maintenance

Cons

  • Casing is Large
  • Not The Best For Travelling
  • Not The Strongest Humidifier

Overview

Music Nomad has been a trendy and quality brand in the past. Their products are usually not over-hyped and marketed. You get what you pay for, and this item is no exception.

At about $13, you’ll be able to keep your guitar at relatively consistent humidity. Some people complain that it isn’t that impactful on the humidity level, but it’s only about $15.

If you’re in a cold and wet area and don’t need that much humidity level inside your case, then this would be a smart purchase. The convenient flip-top lets you check if your humid-i-bar sponge is wet or dry.

The sponge does dry out relatively quickly, and the casing is a hard plastic that might stretch the strings a little more than you’d like.

Unique Features

It is defiantly a low maintenance humidifier. The sponge holds 10x its weight in water.

You don’t have to worry about water damage due to the anti-drip material in the casing. Most humidifiers at this price will die over a short period, but this guitar humidifier is an exception.

Most reviews say how long-lasting and durable it is.

Common Questions

Will this work in a gig bag?

The problem with a gig bag is that it wouldn’t hold the humidifier in place as a case would. It might slip out of the strings or slide around.

Can I use city water to soak the sponge?

Distilled house water is recommended and will help make the sponge last longer.

  1. D’Addario Two-Way Humidification System (Editor’s Choice)

D’Addario Two-Way Humidification System - Best Guitar Humidifier

Pros

  • Maintains 45-50% Humidity
  • No Manual Adjusting
  • Easy To Use

Cons

  • Won’t Last Long
  • Flimsy Mesh Holder
  • Doesn’t Work Well In Dry Environments

Overview

The two-way humidity control maintains a constant 45-50% relative humidity within your case.

You don’t have to worry about over or under humidifying. That can be a huge relief when you’re traveling or taking a break from playing for a while.

Sometimes, when the humidity fluctuates over a long time, the wood will become soft and easily mendable. With this product, there are barely any fluctuations.

The two-way system adds and even removes humidity. You won’t find that attribute elsewhere. Some reviews mention that the humid parks don’t last as long as their advertising.

However, one could say that it’s worth going through these packets. You don’t have to worry about maintenance, seasonal changes, and geological locations.

If you live in a hot environment, then the two-way system might not be what you need. Based on some reviews, they don’t work very well in dry regions.

Unique Features

The reason they call it a two-way system is because it can not only increase humidity within your guitar case but also decrease it. That is such a big help when you store away your guitar for a while or are traveling.

No worries about the drip; over humidifying and mold are all very lovely luxuries. No more manually adjusting based on countless factors like environment, season, etc. D’Addario guarantees no drip or mess.

Two packets go inside the pouch, which then hangs into the soundhole. Then, another packet goes under the headstock. After that, you don’t have to worry about anything.

One very negative unique feature has the guitar’s humidity up to a certain percent before using the packets. The product maintains humidity, but it can’t change the humidity from 20% to 50%.

Common Questions

Can you reuse the packets?

Yes, you can. If you leave the packets out in the sun, they’ll soften up, and you can reuse them.

D’Addario doesn’t recommend this, though. They do lose some of their effectiveness.

  1. Kyser Humidifier for Acoustic Guitars

Kyser Humidifier for Acoustic Guitars - one of the Best Guitar Humidifiers

Pros

  • Absorbs Excess Moisture
  • Provides Humidity Throughout Body
  • Very Good for Dry Environments

Cons

  • Hard to Set Up
  • It doesn’t Fit into All Sound holes.
  • Might Cause Water Damage

Overview

Ok, just because you saw the words “water damage,” don’t write this off just yet.

This product covers your entire sound hole to ensure consistent humidity is maintained. Unfortunately, it won’t fit all soundholes, so you have to be careful to buy it.

There are plenty of measurements online to tell you if it will fit or not. If you’re careful to make sure you don’t drip any water on the guitar, you probably won’t have a problem.

It’s just a problem if you’re careless and oversoak the sponge, resulting in minor spills. You can use it on both 6 and 12 string guitars.

Also, be careful if your guitar has a nitrocellulose finish. If you were to use this humidifier on, say, a Martin D-18 with a nitro cell finish, you could end up with discoloration around the soundhole.

Unique Features

This humidifier will cover your entire soundhole, which provides a seal for little to no fluctuations of humidity levels.

It provides free convection and distributed humidity throughout the body. If you live in a hot and dry environment, this would be a brilliant purchase.

Common Questions

What size will it fit on?

It’ll fit on any dreadnaught, any standard body, and jumbo size for most makers. It might not wholly seal on the jumbo sound holes, though.

What will “excess absorbing moisture” do?

Well, it won’t regulate the humidity like the D’Addario system, but it’ll help with any excess spills you may have caused.

  1. Oasis OH06 Case Humidifier

Oasis OH06 Case Humidifier

Pros

  • Great For Storage/Travel
  • Can Raise Humidity Level By 10%
  • Refill Indicator

Cons

  • Dries Out Quickly
  • Reports Of Leaks
  • Frequent Refill

Overview

If you decide to store away your guitar for an extended period, this might be an investment for you.

You have to refill the container with water frequently, but if you keep a schedule and stick to it, it’s no problem. It’s effortless to refill/use, and you don’t even have to take it out of your case to refill it.

Another bonus is that it can change the humidity by a considerable percentage. Most humidifiers aren’t capable of changing humidity too much but instead maintaining them.

The Oasis does both. You can use this for any wooden instrument in a case.

Two magnets are within the humidifier and attach to the instrument case with a steel belt clip’s help. A syringe comes with your purchase to make refilling even easier.

Unique Features

All you have to worry about with this humidifier is when to refill it. Just open the case, and look to see if the water indicator tells you if the Oasis is full or not.

Most reviews note how impressive the humidity levels are inside the case. A consistent level is maintained, and most of the time won’t fluctuate.

There are some negative reviews of minor leaks. The leaks usually occur about six months in and don’t happen to everyone.

It depends on how often you refill it. If you don’t keep up on a schedule, it might dry up, and then the next time you fill it, there might be a minor condensation issue.

It’s nice that you don’t have to have the humidifier resting in the soundhole or on the strings. This way, there’s less likely a chance for water damage, and the whole case, inside and outside of the guitar, is evenly humidified.

Common Questions

How often do I add water?

You’ll probably have to refill it an average of once a week. It depends on how humid your environment already is.

Will this work on a soft case?

No, it won’t be able to clip on to any sides. It’s designed to be in a hard case.

  1. Dampit Guitar Humidifier

Dampit Guitar Humidifier

Pros

  • For Large Guitars
  • Durable
  • Easy To Use

Cons

  • Don’t OverFill!
  • Frequent Refills
  • Dries Out Quickly

Overview

Careful when you buy this item because many other humidifiers look the same but are not effective.

Dampits have been protecting wood instruments since 1966 and have been popular among the most famous guitarists. It can raise humidity by a much more significant percentage than most humidifiers.

You don’t have to worry about any damage to your strings because there is no clip or soundhole cover. All you have to do is fill it up and rest it in your soundhole.

Some negative reviews mention that you might have some leakage problems if you overfill it, which can cause water damage. As long as you are careful when you fill it, you won’t have that problem.

Unique Features

Out of the five humidifiers reviewed, this is probably the easiest to use. It’s also probably the most durable and long-lasting. Dampits have been selling high-quality and practical products/humidifiers for over 50 years.

The unique thing about this humidifier is that, well, it’s not that unique. It doesn’t have fancy clips or indicators, but it gets the job done. Whether you live in a hot environment or a cold one, this humidifier is simple and downright functional.

Common Questions

Wait, are there two different kinds of Dampits?

You can either buy the smaller Dampit or the larger version. The larger version includes a soundhole cover and a humidity indicator.

Should I get an indicator for the smaller version?

It’s your choice, but it’s always nice to have peace of mind that you’re not over humidifying.

How to Pick a Good Guitar Humidifier

Do I Need A Humidifier?

If you’re serious about playing your guitar and want to get the most out of the money you spent, you need to get a humidifier.

The best musicians use them. Sweet tones will be lost as the guitar warps and bends.

Some of these tones are brand signatures. You won’t find the tones that a Martin produces in any other car. To preserve those, you need a humidifier.

What You Should Look For In A Humidifier

  1. Sound Hole Humidifiers cover either the guitar’s soundhole or are placed in between the strings down to the soundhole. You’ll find most people use this kind because they don’t cost as much and are a simple design.
  2. Guitar Case Humidifiers sit inside your guitar case. That keeps the entire case in a humid environment. But you have to be careful not to over humidify. With guitar case humidifiers, you might need to buy a sealed case to ensure moisture doesn’t escape. You might also want to invest in a humidity regulator.
  3. Room Humidifiers do what their name says. These are used if your guitar (or guitars) are mounted on a wall. If you don’t have a case, you could get a room humidifier and leave the door closed.

Can I Over-Humidify?

Just like an extra dry guitar will warp and crack, a wet one will bend and lose its tone just as much. It’s important to regulate what humidity your guitar needs.

You’ll probably want to buy a regulator. Fortunately, some humidifiers come with built-in regulators. We’ll get into that later.

Be Aware of Your Environment

Keep in mind, where you live should affect your purchase/how often you use a humidifier.

If you live in a cool and wet environment, then you might not even need a humidifier. If you’re somewhere hot, you might need to keep your case at high humidity all the time.

Also, keep in mind the change of seasons. Too many people rush in a make a quick purchase, but there are so many different factors you have to pay attention to.

Although there are many factors, paying close attention to them will result in a healthy guitar that will last you several good years. It’ll keep its tone and signature sound. Now, onto the reviews!

The Best Guitar Humidifier: Our Verdict

It’s well worth the money and is defiantly the best guitar humidifier on the market.
