Bests & Worsts Reviews from Amazon

For each of the 5 mornings after I turned this unit on, waking up was like clawing my way out of a drugged state. This is not normal for me, not even on my worst allergy/asthma days. I turned off the unit on day 5 and on morning 6 I was able to wake up with no difficulty. I also smelled ozone on occasion, despite the fact that this unit does not have an ionizer. I am very disappointed, this unit came up in the top 5 for each of my searches for an air purifier that addresses mold.
