When to Use a Humidifier
Generally, when the relative humidity is below 45% it can be dangerous to any acoustic instrument. However, the weather reports will give you the information about the relative humidity outside, and this is not very useful unless you plan on keeping your ukulele outside.
Information that’s important for you is the humidity inside your house. Now, there are two main conditions that can cause a low humidity inside of your home.
It can happen if you live in a high mountain region or a desert which are naturally arid regions or it can happen if you live in a cold climate and your heating system sucks all the moisture out of the air in your apartment.
Since the weather reports are not very useful, the best solution is to get a hygrometer. A hygrometer is a small device that you can put in your gig bag or case and it will keep an eye on the relative humidity of your instrument.
When the hygrometer shows that the relative humidity is below 45% it’s time to start using a humidifier. These devices are relatively cheap and the batteries seem to last forever so you don’t have to worry about that.
Oasis OH-2 is one of the best hygrometers out there. It’s affordable, it’s easy to use, and it’s very accurate.
What is a Humidifier
A humidifier is basically a device that helps you maintain the optimal level of humidity so that the wood from which your instrument is made doesn’t wreck because of the weather changes.
Ukulele humidifiers might sound a bit alien, but it is a very important device (especially in dry climates) that will keep your uke in shape for a long time.
Why is Humidification Important
Well, it has been seen how devastating effects can changing climate have on acoustic instruments. Dry winters and extreme temperatures always mean a low humidity and lack of moisture in the air and that can create a serious impact on your ukulele.
If you don’t take proper steps on time, these conditions can seriously affect your ukes overall playability, sound, and performance.
Not only that the humidification increases the longevity and the performance of your instrument, but it also keeps the value of your instrument in case you want to sell it at some point in the future.
How Humidifiers Work
Best ukulele humidifiers balance the overall humidity and temperature in the air surrounding your instrument.
Most of the humidifiers are attached to a ukulele case or you insert them between your uke’s strings so they can keep the tonewood of your instrument well moistened.
The humidifiers usually made of plastic with a sponge inside. Before you attach them to your ukulele case or the instrument itself, you need to moisten the sponge with distilled water.
In combination with a hygrometer, humidifier helps you maintain the perfect humidity for your uke.
What to Consider Before Buying a Humidifier
Without a good humidifier, your instrument might lose its base easily and you will be left with a terrible tone. Since solid wood instruments are expensive you don’t want to leave it in such condition and waste your spent cash.
Here are some of the most important things to consider when buying a humidifier for your beloved ukulele.
- The optimal humidity for your instrument is between 45 and 55 percent. Make sure that the humidifier you are buying releases a proper humidity to keep it at an optimal level.
- Also, make sure that the humidifier doesn’t release too much of the humidity because over-humidification can also be dangerous for your ukulele.
- Consider the climate conditions of the area you are living in. if you live in dry areas you might need to use the humidifier for longer periods of time. However, if you live in a colder climate you probably won’t have to use it so often.
- Make sure that you check your humidifier from time to time because if you leave it for a long time it can cause mold growth on your instrument’s wooden parts.
Overall, what your uke need is a perfect balance of humidity. This will protect your instrument and extend its life. A good humidifier will prevent your instrument from damaging and keep it in proper condition.
Reviews of the Best Ukulele Humidifiers
This humidifier keeps the relative humidity in your ukulele case on an optimal 45-50%. It’s a mess and frustration-free because it’s not one of the refillable humidifiers. Instead, it uses soft mesh pouches that both remove and add moisture when needed, hence the name “two-way humidification system”.
It provides unique “two-way” control over humidity and it allows you to remove or increase the moisture in your ukulele case.
The mesh pouches will become firm after 2 to 6 months of use and that’s when you need to remove the pack and put in the new one. It’s really simple to use.
However, this might be a downside for some users because you need to buy replacement packs every few months. On the other hand, it is really worth the money, because you get the perfect control over humidity in your case for just a few bucks per pack.
This humidifier is perfect for ukulele players who dislike refillable humidifiers and would like a mess-free alternative. When it comes to price, it’s not very different than the other humidifiers except for the replaceable packs you need to buy every few months.
