Bests & Worsts Reviews from Amazon

I don’t know if this product is authentic. The air purifier came with a filter, and it didn’t smell bad. This replacement filter smells terrible, an overwhelming chemical odor. I tried airing it out, I tried running it for a few days, and nothing has changed. It is overwhelming. I assume this is a knock off, although the box looked real. Unfortunately, I threw the box away and can’t return it.
