Bests & Worsts Reviews from Amazon

I wanted to love these. I really did. But the bottom line is: I don't feel any difference. I have had them on since I got them. Both in different rooms, one larger than the other. One of them I closed the door while my kid was at camp and the room smells, feels, exactly as it did before the purifier. Nothing has changed. I would say don't waste your money. september 2018 update Both machines are still on. I have never turned them off since I got them. One room is about 100 sq feet. the other a bit larger. I posted my previous review with 2 stars and started getting harassed by the seller. trying to convince me that it was my mistake while using the product. VERY IMPORTANT: they state the machine is good for up to 96 sq feet (?) I can't remember exactly. But a pretty small size. I went back to the description of the product and it clearly says for SMALL TO MEDIUM rooms. I don't believe 100sq feet is considered a large room. 10 feet by 10 feet is a standard small to medium size room. So I changed my review to 1 star because: misleading information on the description. Harassment by the company to, I believe, blame me and make me change my review and most importantly THE PRODUCT DOES NOT WORK. Like I said before. Don't waste your money.
