Product review (1 stars): Opt for something safer
I was bit hesitant about using this product with all the warnings on the label. It is bad for your eyes, skin, and lungs?
So why would you want to put it in a humidifier? Well that said, I used it for two days and had minor chest pains and headaches.
I had burning sensations in both nostrils. I would not recommend this product and opt for something with less chemicals. Its pretty bad stuff.
