Same thing happens with me, I also get a sore throat using it. I was reading some articles and apparently these mosquito coils, vaporisers etc. contain a lot of chemicals potentially capable of causing lung cancer. And knowing this is India, the government is not going to give a shit about researching and regulating the use of these. I have searching for alternatives that contain less chemicals.Samuel said:If I have All out turned on where I am, my nose feels weird and I have to turn it off.It apparently tries to kill me.
