Case Humidifiers

November 22, 2016 at 04:25 PM · Hello,

For a few years, I've enjoyed using:


as my case humidifiers. The instructions with the humidifier instructs dipping the humidifier in bleach. Couple weeks ago, I decided to clean the humidifier for the first time, I left in the bleach for too long, and the filter entirely dissolved.

As a replacement, I ended up buying this:


It seems to do an excellent job maintaining 60%RH in the case, while its predecessor was finicky 40~70%RH.

Also, the new one seems always thirsty, as it is in its "dry" position every 3 days.

I'm wondering what some people can recommend for case humidifier that will act as (de)humidifier and will last over 1 week without refill(while being smaller than 15cm x 2cm x 2cm).

November 23, 2016 at 05:04 AM · Dave, I actually liked the original. I will probably buy another one at a given time.

However, it was a high maintenance humidifier. It wanted Distilled water, and required regular cleaning. I could literally see the salts building up on the filter.

On the ideal case, very good product, but less-than idea, not so good. Also, basically 1 month of use takes it out of ideal condition.

November 23, 2016 at 06:11 AM · Andrew, as a very inexperienced house-keeping student, I left the humidifier in a mason jar filled with industrial grade bleach and watched the filter going from black to white(black was due to salts), then fell asleep in between, and woke up to observe no filter.

Excellent humidifier for very cheap. I only need to wet the sponge every month or so and I live in a very dry climate.

November 25, 2016 at 04:15 PM · I have used the sponge method that Michael does for some years now. It works very well. Just make sure that you squeeze out the extra water before putting the sponge in the container.

November 25, 2016 at 05:43 PM · One of the larger advantages in the gel-humidifiers I like the most is that it is water absorbent, and will maintain RH inside the case. This is important to me because I found that in the summer, my case turns into steam box given that it has enough moisture in it.

November 25, 2016 at 09:14 PM · Most anything we put in a case will release or absorb moisture to some extent, including the fiddle.

I don't know of any particular advantages to "gels", except that they are less likely to release liquid water, perhaps reducing the hazards of in-case humidification a little bit.

What I've always recommended, and continue to recommend, is maintaining proper humidity in the room environment.

Excellent point about getting out extra water. I should have mentioned it.

November 25, 2016 at 10:59 PM · "What I've always recommended, and continue to recommend, is maintaining proper humidity in the room environment."

That's very well when your instrument stays at home, but the hours and hours in dry halls or teaching studios or airplanes or hotel rooms call for some kind of measure to keep it from drying out too much.

November 26, 2016 at 02:50 AM · An untested concern of mine right now, is to carry my violin in its case outdoors in Canadian winter. I have two thermo-hygrometers, one inside and one outside. I am working a device that can remotely observe both, and also control the temperature to a degree(2 biggest challenges are power supply and having uniform temperature gradient so that the whole case maintains temperature, not just locally around the neck , or bout). The outerone has so far reached -15 deg at 20RH, and inside at 5 deg at 50RH.

I'm concerned about potentially damaging the violin as the winter is just getting started. Not to mention that the temperature inside is creeping down to freezing temperature.

I do walk ~2km outdoors from and to my place of work.

The questions are that should I even be walking outdoors for 15~30mins with the violin in the winter? In previous years, I had a wooden case, and just did not walk with it in the winter because I was afraid of falling on the ice and breaking the violin.

November 26, 2016 at 04:53 AM · Maybe you should consider a CF violin?

November 26, 2016 at 02:14 PM · Insulated case bag?

November 27, 2016 at 12:43 AM · Extreme low temperatures and humidity such as experienced at -15C and less is a real challenge indeed. Not certain what I would do if my instrument was subjected to it for any significant period of time. There isn't a case on the planet I know of that will insulate the instrument for much very long at those temperatures. Think about leaving your violin in a deep freezer for two + hours (I've seen sustained -25C for weeks, not counting wind chill), want to try? The real challenge is to maintain the humidity level at sub-freezing temperatures. That isn't to mention the time required to slowly warm up the instrument while in its case to room temperature. I and my violin glad we don't have to deal with that. My violin likes a cozy 62RH! If I were in that position, I'd probably avoid it altogether, and use a warm car/cab to/from places.

November 28, 2016 at 05:14 PM · I've e-mailed the GEWA company regarding extreme temperatures and this is the response:

Hello Steven,

I forwarded your question to our product specialist for cases and bags. He said he recommends to use our rucksacks 300.850 or 300.851. The rucksack is padded and offers additional insulation that will come in handy in your somewhat extreme weather conditions. The Jaeger case itself is a good case for less extreme winters but in your case we recommend to use the backpack as well. Here is a link which you can show The Sound Post (and which they can show the Canadian distributor who buys with us).

The short end of it is that they are recommending an over-the-case insulated bag.

I think the bottom of

is the one they are recommending, I am going to confirm then order them.

November 28, 2016 at 10:23 PM · I wouldn't use a humidifier in the case. Also those dam pits that violinists use are terrible for instruments. They can sometimes cause internal damage to an instrument with moisture. So those are a definite no no. I am an advocate for getting a humidifier for your room where you store your instrument. I set mine to around 60%. It is important to give your instruments enough humidity in the winter time, especially if you have a fine old instrument like a Strad, Gagliano, Guadagnini, or Vuillaume.

November 28, 2016 at 10:36 PM · My apartment stays at overall 30~50%RH, depending on if I did the dishes, and had time to fill the humidifiers. I also have a dedicated humidifier next to where my case sits,that holds RH to 60% locally, also the internal humidifier in the case.

As mentioned a few times, my room is the least worrisome place to keep my violin in, but carrying the violin elsewhere kind of makes me feel worried.

November 30, 2016 at 06:51 PM · In addition to a room humidifier in my practice room, I am using the Precipitube from Lashof and I like it a lot. It maintains RH at 50% quite consistently when the case is closed.
