This article might be completely factually correct but its overall quality is pretty bad. It doesn't tell you whether these chemicals are found in the liquid, in the vapor, or in both. No exploration of what the vaporization process does to these chemicals or whether there are types of plug-in fresheners that don't contain hazardous chemicals. No attempt to quantify what is and isn't a dangerous concentration. If my brother keeps one in his closed bathroom do I need to wake him up to yank it out? If I only have one freshener and it's in the big living room is it safe? Are there any filtration or neutralization methods that let users keep most of the scent while being safer? Then the big question, are scented candles just as bad? This is a kernel of good info but damn it could've been so much better.
