Here's a link to the PVA sponge block that I use:

If you're using water beads or some type of specially concocted process and you seldom need to add water then it may be a tip-off that it really isn't humidifying effectively.
Do you need to use distilled water with the PVA sponges?

Actually you should use distilled water with ALL of these humidification methods. "Need" is a strong term but you'll definitely WANT to (helps to avoids mold and other ickiness).

I use the D'Addario you have pictured, as well as clay humidifiers. I like both. The clay seems to last longer - Calgary is a very dry place, at times (though not today - snowfall warning in affect!)

Thanks for the ideas: I've been using the D'Addario basic ones and I keep my acoustics in their cases as the humidity level can drop to the low 20s here. However, as others have said, the sponges don't hold water all that well and I have to refill them at least once a week ... plus they are getting old. So I'm looking for something to replace the sponges or maybe something to add to the case. Because of space limitations I really can't keep my cases lying down so I don't want to use something like the water beads in a soap holder. I think I will buy one of those super absorbent sponges and cut the parts out to fit inside my plastic units.

Moreover I have three semi-hollow body electrics that I should also think about protecting. I have one of those Damp-Its but I've never used one and I've read that sometimes you have to use more than one. I do have space to keep the cases horizontal so I think I will try those water beads.

And yes, I'm the guy who had the top crack on my Alvarez AD710 a few years back when I left it out on its stand. So it does happen.

I've been able to use the clay humidifiers with my case upright. I sit them on the little "ledge" where the accessory "box" is.

THIS.

The PVA sponge material isn't any more likely to harbor mold than a conventional sponge, but using distilled water will help prevent that, regardless of the type of humidification you use. Water that's labeled as purified is also fine to use. It also has less chance of harboring mold spores.

The replacement PVA material is inexpensive, so if you notice any spots forming just cut a new piece and toss the old sponge.

Any type of humidifier that uses evaporation may result in calcium or mineral build up in the media, but with small guitar humidifiers it washes out and is not a problem. Mineral build-up is more of an issue in a room or whole house humidifier where the media has to be changed once in a while.

Some folks use the ultrasonic humidifiers, but "white dust" that forms on everything is often a by-product. Sometimes when looking for a solution you end up trading one problem for another.

I forgot this, as well. I always use distilled water. Always.

I use the sponge in a perforated baggie that is placed behind the heel. When it gets really cold I add the D’Addario soundhole sponge humidifier.

I use the Boveda system. Works great. I also use Sensorpush to monitor the humidity and temperature. Great combination.
