Regarding Humidifiers

Hi Folks!

I was wondering if anyone uses Humidifiers inside the Case were you leave the flute, or inside the Flute while resting.

If so, which one would you recommend me to buy?

Thanks!
Diego.

it’s the hydrometer that’s tricky

I keep my wood flutes in bait boxes that I found at WalMart. I just cut the dividers down a bit to allow moisture to permeate through the whole thing and line the slots with some polartec fleece. I use a DampIt and sponges for the “moisturizing”. Maintains about 75% humidity according to the digital hygrometer I got from eBay. I should probably put the sponges in something, but they fit (cut down) into a couple of the bait compartments perfectly, so I don’t bother. They do seem to dry out quickly, though. When I was using the “film canister with holes” method, it only got the humidity to about 55% and I wanted 65% at least.

I don’t think many makers would recommend keeping a humidifier inside an assembled flute, but I would think almost all recommend humidifying instruments during winter and I suppose there are probably about as many ways of doing that as there are players. The way I chose to do it was to take a standard mandolin case, tear out the formed foam liner, and then replace it with 2 inch slats I got at Home Depot. The slats go lengthwise and are attached to shorter crosswise ones at the ends to keep from moving about. I disassemble my flutes and place them in this little rack. I keep two types of guitar humidifiers in the case. They sit on top of the rack. One is a spongy snake type, the other is like a sponge in a little box with a grill type top. These are less likely to leak any water than a sponge in a plastic bag and are probably more consistent. I have three hygrometers in the case because they tend to be fickle and sometimes will come up with quite different readings. One is for guitars, one from Radio Shack, and the other a cheapie from Home Depot that seems to work about as well as the other more expensive types.
I can keep about five keyed and unkeyed flutes in this case with no problem and keep the humidity pretty constant. But if I’m going out, then I wrap up the flute I’m taking in a towel and put in in a plastic container with a dampened, but not wet sponge. I don’t use plastic bins at home because the humidity in them can rise too high quite quickly and the humidity levels are just less stable than in a larger instrument case. I wouldn’t humidify a little form fitted flute case for the same reason. But I’m sure others have there own ways that work very well. As for me, I’ve never had an instrument crack.

I thought I read (somewhere) that 45% - 55% was a reasonable range. Isn’t 75% more than necessary?

maybe Pat doesn’t use an air conditioner in the summer…

Yeah, I’d like to know what the makers think about that 75%. I go for about 55% in winter. I would think 75% would pose some danger of rapid drying out once the flute is taken out of its case into a 30% or so room. Of course playing will introduce moisture to offset this, but its not that often that I play a flute from the time I pick it up until the time I put it away–particularly when playing with other instruments. I know guitar builders generally aim to build in a constant 50% humidity. Is 25% more really good for wooden flutes?

Hi! For whatever reason, my flute does not “behave” well if I humidify over 50 to 55 percent. At 75 percent, the keys sort of stick and the pads don’t seal as they should. I have to let it dry back out a bit for a couple of days to get it back up and running.

Hi folks- I haven’t been back here for a while. Busy working (and playing flute). I have a small dampit made for small violins, and I’ve been keeping it inside the second joint of my flute, inside its case. I don’t saturate it, and I rehydrate it every day or every other day in this cold winter while we’re heating with wood.

This flute is cocus, and has been cracked and restored in the headjoint, but the second joint is so thin that I’m afraid of a new crack. I am trying to be soooo careful, but I will be very very sad if something happens to this one. My first antique.

You could put a samich in that bag and have lunch.

I do not recommend tuna or baloney.

Spam might get you about 65% humidity.

why it’s almost 3…I’ve had 2nd lunch

almost time for first dinner!!!

Regarding analog hygrometers, they often require calibration to be accurate. I think most hygrometers can be calibrated, though I’ve read some are not designed to allow it. You can calibrate one at home with a zip lock bag and a bit of salt. Here’s a website describing how.

Best,

My digital hygrometer came with specific instructions NOT to do the “bag” thingee!

Jay, thanks for that link on how to calibrate a hygrometer. I’d been wondering about that!

75% RH is too high for flutes made in North America.

Flutes made in Ireland you can probably just dunk in Guiness when not in use.
