Question about Crane Penguin 1 Gallon Humidifier

Humidifier blows out dust

My BRAND NEW penguin humidifier by Crane seems to blow out a lot of dust. I've never had a humidifier that did this. Is there something in the water that turns to dust? When I breathe in the mist, it feels as though I'm only breathing in dust, not the regular fresh feeling you get when breathing in cool mist. It makes it difficult to breathe rather than easing the dryness. Is there something wrong with the humidifier, water, or house?

Thank you kindly.

As the previous poster said, it's probably a problem with your water.

Are you using tap water or bottled mineral water? If so, there are minerals which get nebulized along with the water, and leaves a white, dusty, residue. I fill my Crane Pig humidifier with DISTILLED water, which is pretty pure. Make sure that the water is DISTILLED ONLY, since some of the water companies distill the water and then add minerals back in (they almost got me here until I noticed the label that said "with minerals added"). The reason this is important is because during the distilling process, the water is boiled, evaporated, and then the vapor is condensed back to liquid. This removes any impurities or dissolved minerals from the water. You can see Wikipedia for more on this topic here.

Additionally, I use both the Crane Demineralization Filter Cartridge (which works for the penguin as well, and gets installed in place of the original water tank cap), and the ProTec PC-1 Humidifier Tank Cleaning Cartridge (which I plop into the water tank) to keep the water both de-mineralized and bacteria free. I got both products at

With these 3 things, so far I haven't had any white dust residue, and the mist feels fresh and clean.

On a side note, by using distilled water, you also prevent any mineralization from building up on the nebulizer or water level sensor, which can cause the humidifier to eventually stop producing mist...

The manual says that you may have hard water - so minerals in your water. This may be the "dust". Try filtered or purified water.
