Bests & Worsts Reviews from Amazon

Disgusting. I am sick to my stomach after running this filter for 10 minutes. I don't know what this chemical is that this filter is offgassing but it is VILE. The original filter was great, had no such issues. I came to write a review and discovered other reviews mentioning the same thing - this apparently is not a new problem and still hasn't been fixed! That is unacceptable. I specifically paid twice as much as the non branded filters to buy directly from Coway to avoid these kinds of issues. Please save your money. Buy a different air filter.
