pro tec cleaning cartrige thank you- this is a tough product to find on the shelves. I have never understood why a company would sell a product (humidifier) but then NOT carry the components needed to make it run....more info

Great water treatment! Really works! I was very skeptical because I have tried many kinds of liquid water treatments and they work OK but not great.
I decided to try these cause they looked so easy and they really are!
I have been using them in 2 humidifiers for about 2 months and they have helped tremendously with the scale build up we get here from the water.

I highly recommend them!...more info

They work quite well I have only used these for my cool mist humidifiers so far (will try these in my warm mist ones during winter) and they do seem to significantly reduce mildew and odor from formining in the tank. Therefore, I do not have to clean humidifier daily - every 3 days is fine. However, there is a dark film that does form in parts of the humidifier that is tough to remove. It is not mold or mildew. Instead, it seems like hard water stains. Otherwise, the item does work fairly well. ...more info
