Product Description

OASIS OH-5 PLUS+ GUITAR HUMIDIFIER FOR ACOUSTIC GUITARS SOUNDHOLE While the original Blue Oasis provides sufficient humidity in many environments, it is not effective everywhere. The humidity demands of the desert, mountain states or frigid north exceed the humidification capacity of the OH-1. For this reason, we have developed the OH-5 Plus+ humidifier. The OH-5 Plus+ is the same size and shape as the original blue Oasis, but is has a different liner which provides 50% more humidity output. Because the OH-5 Plus+ is the same size as the original Blue Oasis and it has 50% greater humidity output, it will be necessary to refill the Oasis OH-5 Plus+ more frequently than the original Blue Oasis. Use the OH-5 when the environment outside the case has a relative humidity of 25% or less. Each OH-5 comes with a stabilizer bar for mounting the OH-5 humidifier and a 10 cc syringe for distilled water filling control. > Because tap and bottled water have dissolved minerals that can clog the liner, distilled water is recommended to extend the useful life of your humidifier

Excellent, but use them properly

Reviewed in the United States on October 15, 2018

Verified Purchase

I have used these for several years after my luthier recommended this brand. He had to repair my "fragile" Martin and suggested this brand to keep it properly hydrated during the winter. I had used "dampits" and homemade humidifiers previously, but these are all I use now. The positive difference was noticeable. Here are some tips for using them and avoiding the problems noted in some negative reviews.

1. Be sure never to let them dry out completely so that the fabric shrivels. Then the fabric may indeed crack like some of the negative reviews state. 2. Clean them out and rinse out the crystals completely when the indoor heating season is over and natural humidity takes over (I live in a humid region when it is not winter so I use them about 6 months before cleaning them out). To the negative reviewer who lives in Las Vegas, you may need to do more for humidity for your instruments given the extreme aridity there. 3. I use fresh crystals at the start of the next indoor heating season and keep them topped off with only distilled water. 4. I replace them after three years before any fabric deterioration occurs.

Are these worth the expense? Your instruments cost hundreds to thousands of dollars. Repair bills are expensive. Consider these a small insurance policy against the damage that can be caused by dehydration.

It feels well-made and lasts longer so far than the sponge ones I have. It stays around 15-20% humidity in my place during the winter, so I hope they keep up.

Does the job, but pricey

I have used these for years and am thankful for them. $20 bucks seems a bit high for it, but we're still trying to come out of the supply chain issues caused by Covid, a war, and the greed of people.
That said, they still work like a champ, and I have never "replaced the crystals" in the past. I use them until they start to look rough (I have a few over 6 yrs old still working fine.

Protect your wooden instruments from low humidity

Reviewed in the United States on January 30, 2024

Verified Purchase

I’m a performing guitarist living in the northeast. Indoor relative humidity levels can be lower than in the Sahara Desert. I have a modest collection of valuable guitars that normally stay in a humidity controlled display cabinet, but when I travel to perform I use Oasis humidifiers to keep my instruments safe. I also have an acoustic bass that’s too large to fit in the cabinet so I rely on Oasis to keep it at the right humidity level.

I did not know my guitar had buckeled just a bit until my guitar guy noticed it. I live in a low humidity, high heat area so I bought this little beauty. Very east to apply and remove. Only needed for the summer months of if humidity is less than 35%.

Thanks for an easy solution.

This is a great product that I've used in multiple instruments. This is the best product I have used (and I've tried several) and I have no qualms about using it with instruments that are irreplaceable. Not inexpensive, but you get a great product that will last years if you buy more crystals to replenish.

I have five high-end guitars and I use these to humidify them to perfect humidity.. about once every 6 months you have to switch out the beads that are inside of them or just replace the whole thing. But when you spend a couple thousand plus dollars on a guitar,it's an investment..great product..I refill them once every 4 days with distilled water

ギターをケースに入れておいて、こうした加湿器が入れないと、乾燥して割れてしまいます。

湿度20%も80%も大変危険です。割れます。特に接着した部分が。

石坂浩二さんがスペインでフラメンコギターを買い、日本に持ち帰って、割れてしまったと話してましたが、これは、メンテナンスを怠ったからではなく、乾燥状態で放置したためです。
割りたくないなら、湿度の調整をこまめにしなければなりません。だいたい30%あたりと言われていますが、これは誤りで、40%は必要です。日本の風土にはこれくらい必要なのです。

弾く時、乾燥している場合には、加湿器を使わない方が良いです。部屋用の加湿器は、カビやウイルスなどを撒き散らし、健康上問題があります。僕の場合、IHクッキングヒーターでお湯を沸かし、加湿しています。これだと、火災防止にも役立ちます。
皆さん、ご参考にして下さい。
